In this video, we’re going to discuss if one coat plastering is ever ok?
Is it ever ok to apply just one coat of plaster?
Most plastering companies demand that you apply two coats of plaster to a wall. This is especially true to the company British Gypsum who makes numerous plastering products like Multi Finish and BG Board Finish. Well, today we’re going to test the effects from applying just one coat of plaster.
This is a hugely controversial topic and one many plasterers argue and fight about. The people who only apply one coat of plaster are often referred to as “cowboys” but the problem is what if it’s ok?
What is you could save time with your plastering and actually get the same finish with the same strength in half the amount of effort?
That’s what we’re going to test in this video. We’re also going to show you some tips and tricks to improve your plastering. This video is aimed for all plasterers because this concerns all of us:
If we could save time and effort whilst getting the same results then why wouldn’t we do it?

Plastering For Beginners - Jak na to + styl
I've one coated for 22 years to a 2mm tolerance it's all about how skilled you are 😅
Ive used one coat on plasterboard and and all sympathetic backgrounds for the last 21 years and NEVER had a problem from any client. I use 2 coat with float and set only. My finish is always excellent due to my experience with the medium. Plasterboard was designed for plastering (the clue is in the title). Always bear in mind your main objective. Preparation for decoration. Its not to provide structural strength or fireproofing. These things are taken into account at the building design stage. If they were'nt tape and joint would be obsolete. 2 coat work is a hangover from days gone by when most backgrounds were sand and cement scratch coats and demanded 2 coat work. As in the above video as long as you apply the muck thick enough its not a problem and should be encouraged. Whenever I see a experienced spread doing 2 coat work on plasterboard I think WTF.. all these years plastering and you still have'nt figured out its a waste of time. Wake up and focus on the objective not the herd mentality..
Yes Gary you’re one I could learn from. Good mentality.
This makes complete sense - very well formulated argument. You've convinced me ha!
You are amazing and I love your videos. Tried the sponge but never worked for me. I do one thick coat for plasterboard and 2 coats for anything else as old walls are not levelled. The first thing I do is to fill the joints as it will be my thickness guide. This is how I have been taught. Thanks again for everything.
Just looked at this video and your comment which makes total sense. Question: What plaster should I use for small area of plasterboard cut in on existing ceiling? There are so many on the market - MultiFinish / Board Finish / Finishing PLaster and even one called 'One Coat'. Thanks
@Gary Wright.. could you give quick timings between toweling etc when one coat sponge process. Would be a great help for me.. thanks mate and thanks for the honest comment!!!!
Hi Blane, you got it spot on doing one coat as you are so skilled. I was shown this method when I first started years ago by an old school teacher as thats how they always used to do it, and only with the steel trowel. Two coats are definitely easier to work with and with the speed skim its a game changer. Thank you for your videos and "plastering blue print" which I bought into. It has changed my plastering ability to another level and I do land surveying as my job, completely unrelated. I'd recommend your course to anyone wanting to learn plastering but my wife says I am a very messy worker! Regards Dom
Hi pal! Thanks for watching - it sounds like you have a bit of experience in plastering and I really appreciate you getting the Blueprint. I hope you're enjoying it...we're all messy at the beginning by the way...me included haha! Thanks again mate. You're a legend.
Useful vid thanks very much for your time and effort, me and plenty others really appreciate it 👍🏻.
Also, as a spread 25 years plus I thought the ox plastic spats were a gimmick but after watching your vids I eventually thought why not, maybe worth a punt. I had the refina 550 steel with a pole for years which is great on ceilings but OMG ox 900 plastic and metal absolutely smash it, a total game changer for me mate! So much better for my poor elbows and shoulders, what a relief as I hate having the Cortizone injections! 😵💫😫.
So, you’ve changed the way I work, more efficient and a lot less wear and tear on the body I’m very grateful to you for that friend
I’ve subbed and you’ve got a viewer for life and I’ve recommended your channel to the lads who no doubt will sub too 👍🏻😁 💪🏻
Thank you so much!! I really appreciate this comment and I'm glad it's helped - especially with your joints! The Speedskim's are a game changer so I'm happy to hear it's helping you. Thanks again...you're a legend. Cheers
This is like watching art, I’d be happy with the finish you did with the plastic blade!
One coat plastering I was taught at college is the difference between’ plastering and skimming’. Rough backgrounds need 2 coats and flat backgrounds usually only need 1. If a flat wall has cracks and needs scrim, then I 2 coat the scrim and 1 coat the rest. If I’m 1 coating a flat wall, as soon as I reach the end of the wall, I immediately go back to the beginning and flatten off with my 30” plastic trowel.
Blaine, this guy i worked for truly made tightness into an art form.
That was the reason for one coat plastering, that & obviously time. i stuck with him for 11 years building loft conversions & we did every trade between us. Boarding them, doing every trade soaking up all that knowledge.
I really honestly thought that that was the proper way to plaster. He never used a sponge float.
The walls were pretty good, not the best i've seen but definitely good enough.
Its only through watching your video's i'm learning where i've been going wrong all these years.
I use both single and double skim and have not had an issue with either. For me it which one I go with entirely depends on the wall condition/wall situation/surface prep etc. Never used a sponge or spatula (may try one soon though). For either method I only use a regular stainless trowel, a superflex trowel and a sprayer and get the same good quality finish with both double and single.
Doing the single doesn't save me much on trowel work as I find myself working the wall more but it does save me doing an extra mix and washing out as many buckets etc (which for some reason I really hate doing)
I learned how to get the best from a single skim by starting out fully expecting to do a double and trying to get the first layer as good as I could, before long I was getting it so good (in certain situations) that I realised I didn't need a second.
Great video's btw. Keep up the good work!
You must be a good plasterer,a totally agree with you ,been doing this trade 17 years , and your comment on washing buckets out , true a hate having to do that ,but straight walls and plaster board only need one coat .
Let's be honest, the main reason one coat work is hated is because it lowers the barrier to entry into plastering. Anything that makes the job easier, faster, efficient will get pushback. If we stick to the 'science' of plastering, as long as the wall is flat, plumb and smooth, then it's good to go regardless of method or technique.
AJ It’s a bit like the ‘art’ of soldering and copper pipework. Ask an experienced plumber his thoughts on push fit and many would say “won’t use it”... I’m a general builder, i’ve been using the stuff for 15yrs, not one leak (touch wood).
@@gdfggggg yup, it's exactly like that. Great analogy.
I think you've hit the nail on the head AJ. That's a very good point mate and a very interesting view on the world off plastering at the moment!
Perfect answer. Nice one.
We only do it one time in Hong Kong. Of course, much fine in craftsmanship in the west
a good few years ago i was learning plastering in college. one coat was heavily frowned upon as it was considered a cheat and crude and not used so we learned bonding then skimming and only using 1 trowel for everything and a feather edge and it was considered bad luck if you got the smallest trowel handed to you by requisition. Only did 1 plastering job after college and basically bottled it and havent done plastering since. Saw your videos pop up while browsing CZcams the other day and now i really want to try plastering again. I just gotta remember how i did things then and hopefully find a small easy job to do first. Keep up the Good Work Blaine your a pro!!
That's crazy...I suppose things have changed a lot since then! It's never too late my friend. I would just start at friends and family and start for free. It's the best way to get experience...I'm sure you'll pick it up in no time pal!
Thanks for watching. I really appreciate and good luck with it all
I did plastering for 2 years I always learned two coats and tbh I e never paid anyone todo my homes but this last week I had a guy in doing a big room for me as my shoulder is actually ruined nowadays, He did one coat.. didn’t put it on thick enough and plastic troweled it he’s made a massive mess in my £1 mill pound home and it’s all cracked and egg shelled, proper pissed off he’s coming back to try fix it but now I’m thinking it’s going to be a skip and sds chisel job and start again… the wife’s paid him as well. If you want to make a video your welcome to come and see this nightmare job he’s leaving. Due too my shoulder I’ll have to try lvl 5 it to save the room.(living room too). Some people shouldn’t be allowed in the public.
Hi mate, a plasterer worked for me in London, he did 3 x 45 m2 ceilings in 5 hours, he worked on scaffolding but only had enough for one ceiling so had to move the scaffolding afer completing each ceiling he one coated all of em, he had 2 labourers the finish was spot on, he only used a trowel hes the fastest plasterer ive seen in my 22 years as a plastering contractor. I can one coat but prefer laying it down with the second coat. The trick is put it on thicker and dont leave it long between each stage and sponge float it, you were spot on in your video, great videos mate, keep it up 👍
Excellent job on a very controversial subject , tried it once before sponge floating became popular and it didn’t turn out well. It is definitely frowned upon, but if you think about when your laying on 2 coats the chemical reaction between the first and second coat becomes one taking into consideration that you put the second coat on at the right time and not left it too long . I think personally as long as your sure you have 3mm thickness and the end quality is as good then all should be ok . It’s not for me though , I would be too worried about not getting it flat enough . Good work matey
Hi mate! Great hearing from you again and thanks again for your constant support pal! I totally agree. If the thickness is the same then surely there can't really be many issues! I suppose it's just breaking the mould and trying something new isn't it!
Thanks for the video, I'm starting a plastering job tmro where its one coat only, I watched this video and feel much more at ease now. What a top video
Thanks for watching and good luck with it my friend. All the best to you
It actually went really well, proud my work after a long time out of the game, abit of revision and education really makes the difference. 😊 thank you.
Best explaining Plasterer on CZcams am a follow of you and I have learnt alot from you over the past year and made a good income from you doing jobs. I started off with short 5 day training course which was basic but then after watching lots of videos I come across yours and ever since I've been on jobs fully confident plastering. Without you I couldn't had done it god bless you brother thank will always continue watching you video's
Mate... What a lovely comment! Thanks a lot for this. It's great to hear that it's working out for you and well done for learning to such a high standard! It's great to hear comments like this so thank you! Keep up the good work my friend 👍
I also follow to better my skills, excellent guy with great help and tips... we’ll done mate and thanks for you vids and inspiration 👍🏻💪🏻🤙🏻
One coat is similar to rendering. Most renders nowadays are one coat, albeit with prep work. But if the prep is sound and the finish is good; then there no reason it’s not viable. Strength, in my opinion, isn’t a worry, as I’ve done second coats with what’s left in the bucket and mixed it up again with the new coat. Great vid and keep up the good work 😊
I'm old school mate...scratch coat.....let it set then top coat...same with skimming...two coats....!!!
Enjoyed your professionalism mate, good content. Did I once see you do a spray plastering video?
1 coat for site and fresh boards
2 coat for old walls
I love your videos . Very informative and I always learn something. Thank you .
Thank you so much. I really appreciate that!!
@@PlasteringForBeginners you are a douchbag
Looks great Blain, doing the dining room today! 😅
Yes Yes hope all are happy n well 👊🏾👳🏾♂️ awesome work 👌🏾
I'm probably gonna get shot for this but hey......... it works for me.
I actually apply two coats of plaster while laying on my first set. Upto a two bag mix dependant on size of the wall.
I lay on sideways from top left to right getting as close to the top & bottom as possible.
Once half way across the wall I then go back to the start then lay vertically from top left to waist height , then from the bottom up. Continue this till the mix is done.
Spray up the plaster with a nice haze. The more water you use , the longer it takes to go off which then gives you a chance to get the other 2 walls on & plenty of time tocover the little shitty bits.
The tools I use is a 15 year old 14"MT to lay on. 1200 speedskim plastic rule. 14" Nela gold.
Thank me later 👊🏾👳🏾♂️
I had my first go at plastering having watched every one of your videos. I boxed in a fireplace and skimmed it afterwards - turned out not half bad. Thanks for the videos!
David Lowe Nothing a smidge of ready mix filler with a light sand here and there won’t sort.
Thanks David I'm glad it's working out mate and you might have a point Slashley 😂
Nice to see all the comments for other people not been plastering for too long so I have always done two coats. Great video mate it's really good to see all the different actions 👍
Thank you Will. I appreciate the support my friend! Cheers 👍
Stick doing 2 coats. It gives a better finish . It's stronger. And less shrinking. It will last alot longer on the joints.
I asked you about one coat not being in your plaster types video a few days ago and now you have a video about it, neat :) I used some white one-coat plaster at my plastering course at college a few weeks ago, it is thick and sticky but i liked it a lot. I had way longer to get it smooth as you could just wet the wall a lot to get more fat to fill in any divets whereas plaster dries much faster so less time to collect fat to get it smooth.
Haha I do listen my friend! Oh ok... I'll have to give it a go. I've never used it to be fair but I'll definately try it! Cheers pal
White one coat plaster is a backing and finish in the same bag not to skim one coat its good for chases and patches you still two coat it
The steel blade Ox is a brilliant bit of kit! I use the ultraflex to finish the set, lovely trowel, I mostley 2 coat but my second coat is what's left of the first mix , watered down, it obviously goes off a lot quicker but if the experience is there, it will save you at least an hour and a half on each set. I've done quite a few one coats in my 35 years of plastering and I've never had an issue with them 👍👍keep up the good work pal.
Eric
Ps you're a very good plasterer 👍
Hi mate!! Great hearing from you pal! Yeah it's a great but of kit - definately makes the job a lot easier. Ok...I know a few plasterers who do it that way and it always looks good. I usually mix 2 seperate costs but it does waste time. I'll give you way a go. Great hearing from you and thanks for the comment. Hope you're well 👍
@@PlasteringForBeginners go for it! All good this end thanks mate, I think the plaster stock seems to be improving, but I wont count on it
I think since speed skims have made one coat much more doable...but your right when you say you need experience...very easy to dig into thicker work with your trowel...
I’ve often used thistle multi finish and done one coat, just mixed it up a bit thicker and slapped it on. Sometimes being traditional for the sake of it is a little counter productive.
That's a very good point mate!
I think you will all find that prior to to 90s and the influx of easier NVQs etc most spreads threw one coat of skim over everything. It would have been very rare to find anyone prior to that time going over their first coat of skim with another as they would have learned to load it up with accuracy and speed. Seems to me like the large amount of followers for the two coat skim method have arisen because they couldn't get it right with one coat. I mean, fair enough, if it looks a bit wobbly or is going on in excessive heat, another coat may be warranted, but if you know what you are doing, there really would not be a problem. Additionally, two coat plastering really refers to solid plastering internally as in backing coat then skimmed when three coat would be scratch, butter/floating and skimmed.
U don't slap it on has to be done at same level , for one coat yes you can do it, only on flat areas plaster board you have to go over the tapes to first .
My bros being a plasterer for 50 years and he never does 2 coat plastering and his work is first class
Another interesting point is when I’m plastering new build property’s, the architects working drawings state “3mm skim coat on boarded walls”. Good luck trying to get 2 lots of finish at 1.5mm depth on each coat.
Bag now states 2mm
One coating if you're new #1 lay in scrim tape #2 minimum 3mm Gage #3 Sponge float #4 Speed Skim.... Great video on plastering most controversial topic.👍👌👏
So far only reason I use 2nd coat is when I mess up 1st one :D. Sometimes when you on your own rushing large surfaces you may loose some quality, then second coat can safe a day. Otherwise single coat only!
You trowel work at the end was a mistake. Use long, as long as possible soft edge blade to finish your work... sponge + water + long soft blade... smaller trowel will only produce dents!
I havent seen many long soft edge blades in UK. You can get them form Europe (up to 2500mm!)... or make one yourself, thin stainless steel sheet attached to piece of wood will do amazing job!
To be honest I’ve done one coat plastering,like you i put the plaster on slightly thicker,it turned out fine,i think using the speed skim is the secret,
The reason i think one coat is scorned upon is because of sagging,but your system ie sponge float,and speed skim seems superb👌,by the way,I’m off to buy a steel blade speed skim.👍
2 coats for show , 1 coat for dough .
Haha brilliant!
😂👍👌
👌
Sound bout right for some.me I'd go with show obviously, just starting out but had the skill awhile back transition from p&d great vids cheers👌👍👊💪💪
We tape all joints with paper tape and first coat joints with setting joint compound. We prime all mudded areas prior to coating wall with colored plaster.
For me depends on the state of the wall your working on , but if I do , always sponge off , I too use ox speed skims , great for saving time
That's does seem to be the general rule of thumb from everyone who's commented actually! It does make sense and yes .. The Speedskim is a brilliant tool 👍
Been plastering for 1 year on my own and i always done one coat system. I learned it all by watching and laboring 2 years for a plasterer whom has done the coat system for 15 years. You said it all in you conclusion: Saves Time and effort, result is perfect when you master it... hence make more money, getting home earlier. To be honest I have not learned the two coats system, I have tried it for few month but i have gone back to one coat. The key is the timing for spraying water and sponging, the earlier after flattening the better. And also apply the right thickness on dips...as you say you only got one chance. So it's good to have a proper look at the wall flatness before... If you master these elements there is no issues.
whats your technique for one coat plastering
@@pauldolton9118 here is a step by step video from the guy who taught me. Let me know if you want more details of a step... The video is quite well explanatory. czcams.com/video/n3ttHRMf5uo/video.html
@@tomjw5027 thank you
2 Coats are stronger, like plywood is made if many different layers, it adds strength. On a new build the house has got to settle, The Chances are 1 coat will crack. 1 coats fine for plasterboard though as theres more flex in the stud wall.
@@jezlanejlI think thickness give the strength. I apply one coat thicker (5mm) from the start then I play with it. In the end I get the same thickness as a two coater who will a 3mm coat then a 2mm coat so same strength in the end. Plywood is strong because of the glue in between the coats of ply. Plaster is different as there's no glue to make it stronger between the two coats . In the end one coat Vs two coats is down to what you prefer. I prefer the one coat less time, less efforts.👍
Been using the spat/sponge system for a while now and was caught short on a job that ran over and banged one coat on a couple walls, exactly the same method as you’ve just used, minus the plaziflex, and was blown away by the result!
We’ve never looked back! The thinking behind it was “what’s the difference than doing wet on wet?” We just mix up a thicker mix, lay up thicker, and we’ve never had one come back, not even on lumpy old walls, in fact, quite the opposite!! We’ve had two massive refurbs off that one job through recommendations!
Obviously there’s intants we’re you have to apply two coats, but for the most part, this one coat system has given us amazing results, cheers for posting!
“Work smarter not harder” 🤙🏼
Thanks for the heads up and it's good to hear that you've never had any call backs! To be honest I've not heard any bad stories from anyone yet which is interesting! It just be a good sign 😂
Plastering For Beginners haha to be honest when we started one coating from that point we questioned ourselves as you are, “are we being cowboys?” 😂
but like I said “what’s the difference?” Fill the Skrim and the beads, let it pull in and bang it on 🤷🏽♂️
It’s the same thickness, flat as a pancake and a nice Matt finish, we’ve been banging out the best work we’ve ever done, for half the effort. If we ever get any come back we’ll be honest and rectify it, but for the last 6 months all has been good!
Love what your doing with the channel too! Keep it up mate 🤙🏼
But it is a short cut.
Plus the person you are doing the work for trusting that you do it the right way. One coating is basically for chancers
@@tapeslayersreviewsreviews9807 very dismal outlook !
One can't always used to be the way ! 2 coats for the lazy kids of the millennium because it's easier to get the finish one coat is fine if you do it right so you need to be skilled as the video proves ! And the trust shown in you by the client is not misplaced because they trusting you to do a good job period !!!! 👌 I know of plenty of 2 coat cowboys that abuse that trust I'm quit often going behind them to put it right !
Great video and an excellent topic the 2 biggest topics 1 coating and sponging and you put them in the same video ... are you insane lol as others have said in the right conditions as in board no problems one coating with sponge all other 2 coats ... well done mate 🖒
Ha thanks a lot Paul I really appreciate that mate - yeah I suppose it is quite contraversial but it's all fun and games mate 😂
I flattern with my second coat use about 2 handboards for a 2 bag gauge and trowel up with a steel refina speed skim
Great job!
Thank you mate!!!
I'm a plumber doing a bathroom did exactly the same thing yesterday , made my own speed skim and it's a great job ready to pva and tile
Good man! Great to hear mate 👍
Yeah right, PVA
I new...but im was thinking many times why i myst do 2cond...gonna crack or what lol....now i red all.here and finally UNDERSTAND 😊 i srarted plastering watch thus channel... thx
What people fail to understand is that if it’s British gypsum, knauf etc….each manafacturer has its own specs and must’s which you need to stick to
It seams so easy when you are doing it :). Still dont fully understand when to use the plastic or steel speedskim. And what would you recommend if I can only buy one?
Keep up the good work!
Hi mate, I've seen alot of new build sites hit in one coat on plaster boards and always looked a good job.
If you don't mind me asking, what size are your speed skims. Looking to invest in one
In my opinion there is one coat plastering with the speed skim tools and not using them. You’ll get a hell of a better job using the ox speed skim to flatten in thicker plaster as it covers more surface area than a trowel. Add the sponge float method and the jobs a gooden
Cool spatula, I had to invent my own tool about 18 years ago. It takes more skill to one coat. It's a bodge but on flat walls and when the cite manager is paying attention. New builds were fare game. But never did one coat on a normal domestic customer.
Germany early 80s I used a machine to spray apply, flatten off with aluminium straight edges and sponge floated, always only 1 coat and great results. Good days.
What sort of pressure are you applying when using the SF, say, in comparison to the ST or your flexi trowel?
My mate does one coat now and then I feel you can see it’s streaky but that just me I guess I’ve been taught the old school way what’s been tried and tested for years it works I won’t change. But each to there own informative video tho mate
I totally agree mate. I'm not a one coat plasterer but it was interesting to see how well the finish came up (which is the only reason I followed it up), but I agree... I'm still 2 coating. It feels right 👍
Thank you Blaine. I am new to this and helping our daughter, who is on a tight budget. Based on the manufacturer's recommendation, US Heritage Group, we are putting only one coat of NHL 3.5 on our new Comfort Block walls. Then we are applying two coats of their Shelter Coat. They said we should brush on the first coat and trowel the second coat of Shelter Coat. Will this last do you think? We will apply a bonding agent to the rough concrete wall before we start but they said we won't need the plastic mesh. I am getting nervous. They said we can always add the brown coat later when we have the funds.
I’ve done it for years on board only, it’s no difference to spreads who 2 coat with same mix as long as you know what your doing, don’t use spats and sponges just traditional and it comes up perfect every time but can understand spreads who not used to it saying it’s for cowboys cus it takes some getting used to even for experienced guys but I always go over skrim and corner beads first
Same here
All very good points here 👍
As for brushes I forgot mine one day and alls i had was a 14 inch decorators brush and it worked great
Spot on bro
Awesome #video as well mate 😎💪
Cheers pal!
Hi, when you put on your first coat, how long do you wait before you apply your second.
Thanks for what you.
I've just done my 1st wall doing 1 coat with the sponge and speed skim same finish as 2 coats. I've been plastering for years I got taught the old ways. but with the new trowels available made it easier to do. you couldn't do it with just a standard trowel that's why old school plasterers don't like it. Your a plasterer and you thought it was good. The problem is when your learning your trained a certain way it's hard to get out the habit it's like wiping your bum with your weak hand feels wrong but persistence is key. Learn new methods great channel
I don't know about other countries but here in UK I think there is the attitude that resists change. Perhaps it is not so bad these days as things change so fast, but years back tradesmen where usually very resistant to any 'advances' in methods and materials. If you look at the major changes that have occurred such as cavity walls replacing solid walls in the 1930's, copper pipe replaceing lead pipework in the 40's and 50's, double glazing plastic or aluminium windows replaceing wood framed glazing units. The list goes on. And now changes seem to happen more rapidly as new materials are devolped. Dot and dab pasterboard replaced the old method of a browning or bonding base coat. That met with some resistance initially as you were 'challenging' the old ways.....
Thanks for the tip I never thought I'd get used to wiping with my left, but now I'm really making inroads
@@manjichromagnon5480 I now use toilet paper! No sticky fingers!
Hi mate, I have been doing one coat plastering for some years plastering for around 14/15 years probs why I get away with it tbh. I do use pva in my skim mix, also I apply a quite tought thick double cream on the one coat I apply which means its usually 2-3 mm thick anyways which is how I get away with 1 coat plasterin but like you say I think for beginners this can be quite tough initially but those more experienced will find this better as theres less work involved. Also mixing one batch is more unified than two batches then appying it so againnfor me 1 coat always win must apply 2-3 mm thick perhaps more 3 mm thickish to begin with if you are going to sponge float the wall as the sponge floating will take about 1 mm out of the wall if you sponge float too early tbh. Theres a lot to think about but ultimately it does come to experience as well as the skill in applying the plaster tbh. We have skimmed walls over 5-6 years ago using one coat skim and it has no cracks so my opinion would be 1 coat not 2 but the layer you mox and use must be 2-3 mm thick and more 3 mm thick if you are going to sponge float. Its hard work paying on that thick and that smooth plus I add pva to my mix to stop it causing cracks on the wall for my customers but yes a lot of hard work tbh. Experience is key, I dont like putting newbies of as i like newboes to lear and try but those who are inexperienced may find 2 coats much easier to apply than one.
I dont mean to be off topic but does someone know a way to get back into an Instagram account?

@Edwin Daxton i really appreciate your reply. I got to the site on google and Im in the hacking process atm.
Seems to take quite some time so I will get back to you later with my results.
@Edwin Daxton it worked and I finally got access to my account again. I'm so happy:D
Thanks so much, you saved my account!
@Bronson Vance Glad I could help =)
The correct way to one coat is
No1 fill out the joints and doorfame
No2 lay on your coat about 3mm
No3 flatten in
No4 wet trowel
No5 wet trowel
Love your channel bud
Thank you so much for your insight! Me and the viewers appreciate it so thanks! Hope you're well pal.
Great viddy once again Blaine. I'm going to try this on my walk-in cupboard ;)
Thanks a lot mate!
On flat plaster board they why not 🤷🏻♂️ long as the scrim is covered as normal
I wouldn’t do it on domestic walls because the first coat has to do more filling for bumps etc plus doing an old domestic wall could have 5 different materials on it (different suctions) etc
Can’t trust it like you would with fresh plaster board
When I was a plasterer, after the first coat , I used to think it was spot on. Problem putting second coat on was, I could miss a tiny area as it was the same shade. Many a jobs I did one coat and it was a brilliant finish. No idea if it lasted though. Only every used a standard trowel and a larger trowel to flatten. Speed skims weren't invented. I was always told to do 2 coats and the second coat must be a fresh mix. SO many use the first mix. Always to NEVER use additives, but now we have some to make the mix last longer. Boy I could have done with that many a times. Its when you rush and panic when the job is stress instead of pleasure
I have always applied the first coat and second coat with the same mix...providing I mix enough ha. But the second coat is kind of my first smooth in, just using enough to give a thin coat and fill any holes or dips and even though the plaster is the same shade I find using the same mix it goes on a lot smoother than the first so is easy to see where has been second coated.
I dont use sponges ir spatulas very often either.
I did one coat plastering on my living room 10 years ago and it still looks fine.
I can't see a problem if you are tiling over it , keep making the videos and please do one about plasterer around sockets and light switches
Good suggestion!! Cheers mate 👍
and how to plaster in tght angles and between decorative coving
Depends on how much time you've pal. I 2 coat. I have one coated. Both good finishes. Obviously it depends on skill too.👍💪😉
Hi mate, great content, im a dryliner by trade but getting into doing the plastering side too, i know i need 2 different trowels, one for finishing, and one for basically getting it on, id go ox for the finishing, but whats the first trowel, is it the marshaltown gold stainless steel permashape 14"×5" finishing trowel? I know id eant something a little wider than the usual ox trowel
Thank you very much for getting me started on plastering. I did a hallway ceiling with a one coat plaster and it looks fairly good. The sponge was really a good advice.
How much time did this really save you? & which would you recommend...... The Rafina Plaziflex or the Superflex? AND What size?
Would u not recomend rounding off the edges of the steel speed skim?
Nice guy excellent video
Thanks Kind regards Mickaeel from Scotland
Thanks a lot mate. I really appreciate that 👍
My pleasure only the truth have a nice evening Mickaeel
Done some single coat recently the finish wasn’t to bad although I found it drying out real quick around the corner beads and pulling when I was trying to flatten in also some cracking appeared when it had dried out ( but that may be because the house was occupied and the heating was on ) apart from them two issues it went well didn’t use the sponge though
Hello mate just a quick question how would you define the difference between skimming/plastering ??
Always on board but 1 coat. Flatten .sponge .flatten steel trowel. Then 1 wet and 1 dry gob done😊
Hi mate thanx for getting back to me about the internal angles using scim stop bead but i will still try it with a scim stop both sides of the angle and butt them together, as for one coat ive never done it and never will do I am old school stuck in my ways cheers Kev keep on spreading, ps have you ever fabricated an arch yourself ?.
Sounds good! Let me know how you get on because I'm intrigued to hear how you do! We've rendered curved archways above Windows before by cutting curves in timber and using it as a template to form the render with. Other than that... No matey 👍
@@PlasteringForBeginners Yes that is how to do it but on an interior arch you must fix some old scrap bits of wood to the corners and fix plasterboard to it to create a base then shape your arch with some board both sides then using some left over bonding fill it in, next day just fill the sides, once dry coat the lot with finish using bead and flexi bead, I know there are arch laths but to me that's cheating with this you can create many shapes even Victorian or Georgian styles I hope this helps and please I don't mean to tell you your job just ideas and help, you do a great job so rock on buddy ill let you know how the angle goes. Kev
Is this using standard multi finish thick for one coat or is it one of the marketed one coat plasters?
I've just plastered my brothers home bar.. I'm a novice but I layed it on thick, only problem I had was I didn't have my refina flex trowel as it was on order and not delivered in time. The finish wasn't amazing but looked ok (personal thoughts 2nd needed)
What people fail to understand is that any system whether it be British gypsum, knauf…etc have their own specs and must’s that you must adhere to especially on site work
If the old plaster applied to brick was a total of roughly an inch thick, could I use two coats of One Coat, or two coats of Bonding, then one coat of multifinish? Would that work? Would I scratch in between?
As DIY'ey I did a single coat on a small area.... It worked out ok. I did go on a plastering course and so learnt some of the basics to get a smooth finish. I did notice somme hairline cracks once it dried but wasn't too bad. Cheers for the videos!
Thanks for your insights there and it's interesting to hear about the cracks! Very interesting! Thanks for the comment pal and thanks for watching!
Great job
Thanks mate!!
Hi mate I have a plastic Ox speed skim 1200mm which is amazing going to try a stainless blade when sponge finishing what size is yours please mate ??
Good job. Can you do the same on ceilings?
Depends what I'm going on.
Plasterboard, on coat all day long. No reason for the 2 coat for the afore mentioned reasons. However sponge is a must.
If it's a reskim, artex, bonding etc, then 2 coat all the way.
Nice video, enjoyed it, my technique for one cost is a little different, and I tend to reply on the plastic more, mainly because I want it to go off faster. 👍👍 go home quicker. Lol
This seems to be the case for a lot of people mate and I suppose it all depends on the background your working on. Very good point - great hearing from you! Cheers
I've just used one coat plaster for the first time. I'm not happy with it, can I PVA it and put another coat on. Many thanks.
Hi I've been watching your videos are very informative thank you. It's always been a burning question. Regards to one coat plastering. in fact I've done all my dry walls with bonding 1st. As nothing was straight.. I've just done my today with one coat of skim. Because I have use bonding first and one coat of multi skim. I wonder whether that would be enough for just that one coat as I would think it be strong or should I be doing a 2nd coat. As it looks ok! I would appreciate reply.thanks steve
Hi mate! To be honest, if you've already applied a coat of Bonding and the plaster looks good then I can't really see a problem with it. Others would probably say other wise but in this situation I think 1 coat is ok. Not perfect...but ok. Hope this helps pal 👍
Thanks for the reply. I put the 2 coats on anyway. As I have found it gives you a really nise soft smooth finish. Can I just ask? What's so special about the marshalltown. Say to an average laying on Trowel, I have brought the raveena gold flexi trowel. And raveena plastic straight edge trowel which is brilliant. it really isn't good for laying on. Because of the flex in it. I only have a cheap and laying on Trowell. But I had quite a couple of problems with it sticking to the plaster. As it sucks and sticks like a vacuum hoover and you end up pulling off plaster, lol and can be frustrating. When using the float flat against the wall. I managed to do it with perseverance. Don't have to be very mindful about it. Sticking. Is the marshalltown float as smooth as the raveena flex. As the one I have is just a carbon steel which just rust for fun.!!! I've nearly done my project.now which was plastering the entire kitchen including ceiling lantern roof. Ceiling. And I'm quietly happy with it it's not perfect but I can rectify marks with a bit of sandpaper. I have found that I've been doing work in really bad like because the electricians haven't finished the lights has that can't be done until the ceiling finished as there is spot lights going in. As it's winter the light goes really quickly. And as I am an advanced novice. The jobs taking very long time. It's only in the daylight when you notice it's not the perfect as you thought. Lol Kind regards Steve
Iv one coated for years, along as joints are filled out you should be fine, i put on with stiff trowel, speedskim as I go, one more trowel with stiff trowel then one wet trowel (crossed) then 2 dry finishing trowels (crossed). I never get tiger stripes and in 15 years iv never had my work pulled and I'm on site. I would never one coat re skims though.
Oh and make sure beads are filled out lol
I’m a carpenter and do a bit of plastering I’ve always struggled getting two coats on in time. Always seemed to be chasing my tail.
I always seemed to put it on a bit too thick anyway so gave the sponge a go.
Again I’m not a plasterer but Ifind this a much better way.
I must admit, it is easier! I just prefer 2 coats but if one looks good then what’s the problem?? Fair play pal
You have to be a master of 2 coats first and you must use the sponge float because you can get it as flat as you would with 2 coats before hand , im just still a believer that 2 coats is guaranteed spot on finish , but also use a sponge float if you want to speed things up ,especially blue grit and the pro finish plaster is fukin awesome for speeding things up , you just have to learn its timing 😀
Seriously lol, fill out your tapered edge board joints without leaving thick lips then just put a good coat on ,if u can't do that as a time served plasterer,well
Very interesting 🤔. What’s the wall look like now?
Hi. May I know how long the speed trowel ?
I am a complete novice and haven't got a clue. I want to plaster a wall but I was wondering is there a beading that can be used that would allow one to run the spatula across a section, plaster it, level it and then move on to the next section? So there would be a series of beads across the wall and each section would be plastered.
Also to add it is on new plaster boards. All scrim tape have been covered British gypsum bonding. As the the Joyce's are in level. So I had to work very hard to get it as level as as possible on ceiling. I dot and dab plaster boards to the wall. Again the walls were not straight which made the plasterboard harder to be level as well. So I put my scrim tape on. And again put British gypsum bonding on. So the walls and the walls are straight as can be. So there goes the question. Putting a decent one coat multi-finish skim should that be enough. ? thanks
3.50 a m2 on my site I’m never two coating get in and out , painters love my work 🤗
I think it’s low suction background we’re you need the second coat , on board 1 is enough
£3.50 ???
just got on site me self will be one coating we're on £3.25
blimey you can come and plaster my house for 3.50 a m2
being a self-taught plasterer I have always done one coat using multi finish plaster and I can happily say I have never had any problems. no cracks or anything out of the ordinary as long as the backing you going on too. is solid and not moving that much and have been doing this for about 11yrs now on my own properties and friends and families. I have always known this is not the right way to do it but because I have success every time I have been reluctant to make more work for myself by going over what I have already done.
Nice to here your thoughts on this 1 mate and how it works today with plastering my dad was a house repairer (builder) back in the day when he plastered it was always 1 heavy coat then floated up he was old school so interesting to think nowadays that would be a bad way to learn plastering? Been liking your videos a lot mate thanks for taking the time to do them 👍🏻👍🏻
It's interesting to hear how your dad did it - thanks for the insight there mate! It's a massive topic and I want to friend into it! Thanks for your support I really appreciate it. Cheers 👍
@@PlasteringForBeginners Absolutely love your videos, after searching many videos in order to learn plastering, yours are the ones that keep cropping up that are explained in a way that i understand.
Thanks Andy I really appreciate that pal! Glad to hear that's it's working out and good luck with your plastering 👍
@@PlasteringForBeginners I'll need it! Im a bricklayer by trade😅 im on my 5th room, every room i do gets better, the first two are not the best, the 3rd room was tricky with angled walls and a vaulted ceiling and the only bit that im not overly happy with is the curved vault, i decided to curve it because the truss line wasnt perfect which reflected in the plasterboard, the 4th and 5th room i am really happy with but i did manage to get some ripples one side of a window where i got cocky and took on too much at once, i cant wait to try the next room
Plastering For Beginners the big Q now is are you a 1 coat cowboy 👩🏼🌾 mate lol
Eight times out of ten, I tend to second coat with the same mix as I like to attack the walls while there still abit wet so I can control the set better and they pull in at the same time,I do tend to use a fresh mix if I have bigger hits to do but people say I 1 coat by laying in with the same mix I think it's 2 but it's all swings and roundabouts
Hi mate! I've often plastered the way you've said and it does work well because it pulls in at the same time. There's no division between the 2 coats is there! Totally agree. Cheers man!
Thats exactly how i plaster. Double back with the same mix, while laying in second, you are actually flattening in the first. I once had a subbie i was working for for months with no complaints, was plastering a ceiling and watched me double back with the same batch on the second coat, and accused me of cheating, well i said to him, you been paying me without complaining all this time so whats the problem? He believed in flattening in te first, mixing a second coat and then waiting. Like someone said earlier, the whole 2 coat system goes bacl to sand and cement and hessian scrim. 2 coats, but with the same mix. You can shave off up to 45 mins +. Nice videos. Do one on multi v board and 2 interal angles.
Stewie.spot on.2nd coat with same mix.thats the way forward& cuts set time down..
That’s the way to go, at least on small walls
I'm not a plasterer now but I still do bits and that's the way I was taught, my teacher never gets complaints and nor have I.
After nearly 30 years I’m still undecided .Bloke who taught me years ago showed me one coat on boards and hessian Skyrim cloth 😁he was good at it and I did for a time but saw a job when it dried and went to two coat and carried on doing it sponge seems essential for it but using a sponge seems unnatural to me like your ruining your wall so never tried,also seems to be a lot of trowelling going on as opposed to the old two coats and two /three trowels over and a polish with steel and get down pub .good vids though mate,interesting 👍
Hi mate! Great hearing from you. I think you're right and the sponge is definately essential if you're one coat plastering. I still think 2 coats is best (it has to be), but it was just an interesting test to run and I must admit I'll probably do it again but I'll be 2 coating for the majority. I haven't gone to the dark side yet lol! Great hearing from you and thank you for watching 👍
used to one coat on board in the 90s, mt
Back in the day one coat all the time.we used to add a big handful of carlite finish to hold it back.i was told put it on thin take it off thick
This is mad mate! Are you still plastering then? Great hearing from you mate, cheers!
@@PlasteringForBeginnersI build recording studios now so not picked my trowel up in anger for about 8 years. Done some big plastering jobs over the years including strangeways prison after the riots, (3 coats of sand and cement with hardener in ) this was spread over welded mesh on the ceilings and walls of the cells.great trade and good memorys
I'm a plaster of nearly thirty year's always one coat with lay in with same mix just trowels thinkg bout getting speed skim now
I think the reason for the two coats is more to do with the old hessian scrim which was impossible to cover with one coat. I would be interested to know your view on Multi finish versus Board Finish.
On another point the moisture resistant plasterboard is not made for plastering. BG say you should tile directly onto it and that introducing a layer of plaster in between the board and the tile adhesive negates the purpose. There are, of course, places where the tiles end and you need a skim coat but they say the board should be primed with a bonding agent such as Blue Grit before plastering. I hardly ever see this done but I have heard of cases where it has shelled off so I do it just to be safe.
I did not know that about moisture board. Thanks for that. Every day's a school day
Hi mate! Great hearing from you again. That's a very good point about the old Hessian scrim - it was thick stuff! I've always used Multi Finish to be honest mate so I don't really know anything other than that. However, I was very impressed the few times I did use Board Finish.
I didn't have a clue about this fact about plastering on moisture board! That's very interesting. Thanks for giving me the heads up on that because that's totally new to me! Great hearing from you and I hope your channel is going well pal! Cheers 👍
Oh and thanks for recommending viewers to my channel! I really appreciate it! Thank you 🍻
@@PlasteringForBeginners your the boy that's why!
Need a vid for the site lads comparing time saving techniques.
Also never used the plazzi for anything other than smoothing second coat when not using a spat find it skuffs to much? Do you buff the edges and round the corners or straight of box?
Moisture resistant boards don't need done, when tiled but when plastering ,blue grit is best , or a neat PVA apply twice ,a found that good on any boards ,on the sound proof boards , which are blue ,and the fire resistant , always bond with blue grit ,a found out the hard way ,it cracks a few weeks later if u don't. And board finish is good for standard plaster board , don't use on any other surfaces
Very nice
Cheers pal!
The board joint needs 2 coats. I have done it when you can get away with it. Think the idea is you can hit many walls as it hangs for alot longer
