I fired 2 "Professionals" and did the work myself (first time ever working with drywall), exactly the way you showed how to do this work correctly. My work was fantastic! Thank you so much for sharing your knowledge.
Probably professional bsers
Best advice from the "Drywall Doctor" is "walk away, let it dry...."
Drywall Doctor you the man and no arrogance. Keep teaching us weekend warriors. I got new tools and some scrap boards to practice on. Will let you know how it goes.
This man is truly a professional. Amazing. Deepest respect and thanks
did my whole house with regular green lid usg brand heavy mud 30 years ago, no cracks 30 years later
As a contractor I have to say that he is really good.
I know an old man who used a concrete trowel and he goes back and makes the half dry mud wet!
And skim coats it flat.
I still took sand paper across it lightly to bother him but it disnt need sanded at all.
I even checked it with an angled flashlight
I've only been doing this for 8 years or so, I enjoy watching people with greater experience do their thing, maybe there's something there that I can reflect on or learn from, 100 percent agree that there's not much I can't coat out with a 10" knife. Never been a fan of a 12" unless I am just pulling mud off the wall for a skim. It might just be me but I've never had much luck with taping a joint and immediately coating again right after, hot mud to tape and taping for first seems to work alright but I still let the tape dry prior to recoating, 2nd/3rd I let it dry enough that I can Scrape the ridges and coat again. I only sand after my finish coat which, like you, I pull tight, try to keep it clean just to minimize sanding.
Nice Video, thanks.
Try anything with an 8 im on fire
Old polish guy from NJ taught me this way, durabond 90, easy sand 90, joint compound, mud tight, mud tight, touch up with light sand. He did everything with a hawk, 6" knife, and 10" trowel, he never liked the big knives
This video is so inspirational. I knew it could be done like this but you confirmed it. This info is worth more than CZcams likes. Thank you my dude!
Drywall doctor, I would like to tell you, thanks for your help on the butt joint video.
everything you say helped me do a better flat joint. Thank you sir.
Great, easy to understand video! Thanks a lot for advices!!!!
Back when construction workers were respected professionals.
That was back in the 60’s.,.
Don't worry guys budding professional here there's plenty of us that still care about our customer and the Lord Jesus
as nobody wants to work or learn its coming around again!
Thank you so much amazing videos I just learning how to do this type of job in my house 🏡
Hey doc, here in eastern Canada we use 12-14 inch curved trowels to finish our seams, it's cool seeing how others use different methods!
stargateproductions Groovey Man, Far out!
I'm from Nova Scotia myself ! I cover my tape with a 10" Knife then double with a 14" bow trowel. Then I'll skim with my 12" flat trowel depending on what's needed !
Very good videos I learn a lot.thank you!
And I was going to cover my joints with molding. Nice Job!
Awesome video. Can you do one on installing expansion joints with a laser or level? Thanks
Great instruction. Thank you.
This was you at your finest instruction.
Man after my own heart. I'm retired now but I've been doing double 10 and double 12 on butt joints for 30 years. You young guys, pay attention.
I just started doing drywall this past year. I usually double 12 twice after I tape. You're telling me I can use a 10 first? Thank the lord I can set down the giant 12 for at least one coat lol.
Awesome video !!
Glad to finally see someone using sheetrock/durabond for the first coat. Premix mud has NO place in any first coat.
Less is more if you're new. Always pull your work tight.
Hardest part of taping for newbies is to know when to stop touching it and leave it alone/allow to dry.
harder to find now
What I love about this video he feat straight to it. No nonsense Justin what I like
Good thanks again doctor.
nice, i stopped using the 12 also lol dam near use a 10 for everything besides troweling and boxing bead that is,... again some really good pointers
hello. I hope you see this and reply, I would really appreciate it. when you wipe down the middle the last time will it be flat even if your knife isn't? is your knife flat? ive notice it doesn't take long and the 10 inch knife becomes convex or concave depending on which way you hold it. advice on how to deal with this please? I never learnt hawk and trowel and don't want to start now but trowel stays straight.
I almost always prefill w/plus 3 -- straight out of the box. Never have cracks, lol... Love the Doc though, always good to get a new perspective. You do however want the prefil to dry b4taping. So if ur in a cold/damp basement or garage...yeah i can see durabond there for sure, so you don't have problems
As you said do as the manufactor direction, I see that you nailed only a few nails on the green boards, especial the backerboard in the bathtub area nails space like 12" too ......
Gotta say it this old man knows how it has to be done so everything looks good when painted
I always get scratches in my durabond unless I soup it way up, it seems to take a bit more water to get the clumps out than any other mud. Hardest one to use lol need a machine to sand it if you don't get it right.
How do you do a butt joint on steel rounded corners ? I have a 26 ft. run for a half wall, aka. garden view basement. Thx.
Hey drywall doctor it's a pleasure to see your videos I love all of them... Mister Ray ,I have been doing what you do, and I have been doing it for years except I don't use Dura Bond because they don't sell Dura Bond here in the Rio Grande Valley Texas... At least I haven't been able to find it by I use easy sand USG brand to pre-fill before I tape but for a different reason ,because when you pre-fill you stop blisters, from happening in the tape when you have large gaps.... It's an extra step other type of floaters in my area don't do. But I have always done.... now will USG still recognize my method as good if I use easy sand 90 instead of durabond 90 to do a pre-fill?
Thank you it's just that here and they're Lower Rio Grande Valley they just slap the houses together I'm a damaged drywall repair specialist and what I do is I correct the mistakes all these guys are leaving behind.... Thank you for your channel I learned a lot of stuff from you....... You can find my videos in (DDR Express) DDR stands for damaged drywall repair.. my company has its own channel...
I am a younger handyman who does daily drywall repairs. I do not even own a 12-inch knife if that says anything about the utility of it. Also, good work here!
Wow looking good nice to some one who knows what they are doing
Thanks mister doctor?👍👏🏽
I would like to ask as someone with general building knowledge in the uk. this is what you call drywall, we use plasterboard here mostly and it is skimmed all over and finish flat with a plasterer trowel, and then painted or wallpapered, whichever the client requires. So does this mean that the plastering trade over there is just not required, because you do as a finish just skimming the joints etc,
@@THEDRYWALLDOCTOR1 Many thanks for your very swift reply cheers mate. have a very nice day, great video and very informative.
Hey Doc, ever mud a tapered edge to a butt edge? What do you recommend when a remediation company cuts 2' of drywall from the basement floor up the wall. I have about 223' of drywall that needs to be replaced and I want to save on waste by cutting the drywall in 1/2 long ways and using both top and bottom pieces.
If the company already boarded and put the factory up to the buttjoint, just prefill the factory so you are left with a flat surface. I.e. buttjoint. Once dry it's easy to tape again.
Hey doc, I noticed you pulled out an offset 12 inch, do you use for anything other than bead?
Danm u make this look easy.
I never put paper on with bond! It doesn’t shrink in enough and will bulge out and make a hard jump to float!
This is irrelevant to this video but I have a client who requested that I mud over the joints on vinyl coated gypsum board in a mobile home. Do you recommend oil base primer and then just treat as a regular butt joint or will the way the walls move just cause the joints to crack?
You are absolutely right use a vinyl strip over the seams that's all you can do mud will never hold up. If it's dirty just prime and paint
I agree , theres nothing in drywall finishing i cant do with a 6 a 10 and a pan period .
Can you sand-it to be flat Or is it better to have it flat with compound?
you can watch other videos then watch the Drywall Doctor do it right. I'm on a small renovation now and we are NOT doing it the right way and it's been tough.
Hello how can I smooth my painted Spanish textured wall? New home owner. I want smooth finish so I can paint over it. Thanks
Excellent
Wouldent u use a 12 if you were floating over a complete wall or ceiling?
You need a 1 inch a 2 inch a 6 inch a 10 inch and a 12 inch. I occasionally us a 16 inch. Each knife serves its purpose. Nice to have a knife for scooping too.
I am going to need to do this in a bathroom. So can you just use Durabond for the whole job or do I just use this for the initial taping and then use another type for finishing? Can durband be used to cover the screws as well?
I would use it for the initial taping sorry it took me so long I just saw this comment and yes you can fill in screws just make sure they're dented in cuz it's hard to scrape
I tape the same way,in NYwe do not use durabond with sheetrock,just compound and plaster (when- needed) Some times I mix some plaster In my compound for gabs and if I want to start doing my skim caoting the same day or when I some joints need a little extra care .and i want to start doing my finish coating on that day.I never use plaster when I put the paper on, always straight compound only. I have been hand taping for 25 years. I wished I would have had the bazooka and the other tools tools you use . They are really great tools . Even thoughI have done many houses about (4-5 rooms), by myself at a fast but efficient speed. I can usually do the paper coating in about a day.or sometimes it may take 2 days. But with the tools you use , it would have a better and more efficient way. Also putting less stress on my wrists and knees going up & down scaffolds and ladders. With the tools you have been using.for the last 40 years. If would have know you 25 years ago. I would have differently ask you to show me have to use these tools, I am always willing to learn how to do things more efficiently .You can always show an old dog more efficient tricks,, if they are willing to learn. them. That's what's wrong with some young adults today, they are not willing to learn different ways of doing things to be better at there professions. I do not mean yourself.
I can’t tape in corners with durabond in my part of the world, tape hardens up and splits over time, houses are all 100 plus years old, twenty percent of the homes I work on are plaster and latte walls, I’m constantly trying to tie old crooked plastered walls into new gyprock 2 feet around the bottom, it’s been a wild three years here lol
Nice work. As a novice I have a 12 or 14 inch bowed trowel. By bowed I mean it is not flat but has a slight arch to it. This allows me to spread the durabond out an leave a slight thickness over the joint and the tape which tapers to 0 on each side. I always thought that tape had to be wet with a slurry of durabond. I see that this is not done here so this pro does it this way. In any case I use fibreglass tape because it saves me time from putting on wet paper tape. The only drawback that I can see is the fibreglass is a bit thicker which can be problematic. Also it is more expensive. As an amateur without the high level of skill of this gentleman, fibreglass tape and bowed trowel is what I use for joints.
But wouldn't that give you a rounded area over the joint rather than flat. I only use a curved trowel over bevel joints.
Finally someone who knows they job
Can you show us a video on how you do your drywall? Drywall doctor?
Thanks
So wait you can pre fill, tape, 8 inch coat, 10 inch coat all right there? Or do you let each coat dry but you were showing for demonstration purposes?
You can tape and coat it but it has to set up before you can put a second coat on or a third
you're so good at it! I suck!
Excellento!
As a novice, after you tape with durabond 90 and let it dry, what type of mud do you come back with to float it out? I assume two coats of floating it out then last step sand?
Thx! Is there an alternative to durabond? Can't find a single store that carries it. They tell me EasySand works just the same to prefill and lay down the tape.
In Seattle, everywhere sells Silverset. It's made by USG, the same company that makes Durabond and the Beadex and Sheetrock brands. Even the specialty drywall houses out here don't stock the old school, brown bag Durabond.
In the middle of this at my place right now and have all but lost patience with it. Gunna call someone else to deal with that
What are your thoughts on prefilling an area that is already settled? Doing a basement in a 10 year old house. Do I need to prefill each crack like this or just the larger holes?
Good point, thanks
Doctor- how can primer NOT penetrate the mud / tape and not lock it in? You say it could pop the tape- how's is that even possible?
mike ray look at any house that a bad finisher has done you will see it's possible
Excellent advice. A 10 inch mud knife is easier to wield.
I’m having problems after doing a patch job
Getting the texture to match the rest of the wall
Another worse after painting you can see a patch job
do you have a video for that
You're probably not sanding properly if your repairs are showing, the secret to hiding multiple repairs is to sand them off properly, take a hawk or half pan of finishing mud, load up the area or the wall and scrape it back off, skimming it will even the texture out on the entire wall, light sand and prime and the texture will be even again, I only do that on extremely poor walls, most patch work i do blends just fine with the majority of walls I repaint. Sanding it properly is key. So is knowing how to patch dings and holes... could be a lot of things, but if you still see your patches after repainting, you didn't blend the height out and or didn't sand enough. Maybe they were minor blemishes and instead of smacking them into the wall with the bottom of you taping knife you decide to try to flare out the height of the blemish/damage.. it's easier to dig into a wall and coat it back to flat then it is to try and blend a high spot.
Natural light/higher paint sheens will show everything. This could also be why your repairs are showing.
Thanks for debunking the soap in mud myth.
I have a question doc please help I can I get a perfect cut with the bazooka in the upper angles. My tap keeps pulling so I have to go back an cut lil peace to fix the problem. Its it my mud consisted to running or not to running
I have hung thousands of rolls of tape with a bazooka and what you have to do is make it a little long as you go to move away from the corner with practice you'll get where you'll make them the right length. It also helps as soon as you leave the corner press really hard on the crease wheel.
Thank u I jus figure that out the last couple jobs but now I know I'm doing it right
The best way to cover butt cracks is to pull your pants up...
john633 🥁🥁🥁🥁🥁🥁🥁🥁
Unless you a chick with a whale tail, my God work stops and every dude is 10 yrs old again...lol
Why dont u use easy sand. Just curious
Just had a guy install sheetrock, tape and paint. Now I can see the seams between the sheetrock, I think these are called settlement cracks. Been killing myself trying to fix them. Any help would be greatly appreciated!
Make a video and post it to youtube, show us what's happening and you'll likely get a lot of answers
can you make a sample
Hes doin all the fill in one step cause durabond gets hard as concrete and doesent crack then all you have is your finish coat.instead of multiple coats of mud and chancing it cracking use this instead its old news for me just on deep fill joints cause if you for some reask build it up to high you will be tearing the rock you dont sand durarock
Man, you’re good. But why is your mud yellow? I’m new to your channel so you probably addressed it before, but I don’t know. Is it so it picks up better on video?
Tinted+3 have been using it for years
Yes sir 👍👍
I cut a 45 degree angle and only half way through on both sheets, butt the two sheets together (like welding two sheets of metal when welding a seamless joint) and that way you can sand flush, BUT do this with two application of compound, because compound will not set up inside if it is 3/8 thick or more with one spreading...
Timex that's got to be the dumbest idea I've ever heard....
I thought about doing this as well some years ago. I suppose it adds some more work because you have to bevel the edges manually.
I'm a mechanic but still saw the whole video
Does my butt joint look big in this?
I still don't know how a butt joint look they just showing me how fast and skillful they are damn
Durabond just doesn't shrink as much
Merci 🎉
on a small job can I tape and coat with durabond before the mud sets on the tape?
Yes but keep it tight you can not sand durabon
@@THEDRYWALLDOCTOR1 true, very hard to sand. I use a lighter weight top coating like plus 3.
what do you do when drywall mud the all purpose is drying up on you and making clumps I can't get it smooth when it starts drying?
The Drywall Doctor could it be old from the store it was new!!!
JBIRD575 Get your kids to start picking out all the lumps! (ha)
There could be a few reasons.
1) your not mixing the joint compound correctly to start with.
2) you keep playing with the mud after it has been applied.
3) your not cleaning the sides of your bucket after scooping some out/putting the lid back on thus get crusty's in your mud.
4) you haven't prepped the wall properly.
5) you've gotten a bad batch of mud or somewhere along the way it got to cold/hot thus causing a chemical change to the joint compund formula. (Not too likely but does happen)
Another reason could be that your applying the joint compound too thin/tight on the wall and the drywall has absorbed the water in the mud thus making it gum up if you go over it again.
I notice you only use blue steel knives, whats your thoughts on stainless? One of my finishers only uses blue, but I only use stainless. He cant finish with stainless and I cant finish with blue steel, they are to soft for me and stainless to stiff for him.
mobicube Why dont yinz switch?? Then you'll both be able to finish...lol
Blue steel and carbon steel will rust... if not cared for properly. I use both. In my experience, SS wears out faster, ie my corners round off sooner than carbon steel.
If you think the material your blade is made from makes you a better finisher than others, I’ll leave you to stand on your soap box.
Yup, it's whatever works for you, I use Stainless, the blue ones bend too easily for me, I assume it's because of how much force I put on the blade vs. The height of it, stainless is what 5-6" inches tall and blue is 4 inches maybe? The blue ones they sell around here are always plastic and flimsy where the ss are thich comfortable handles and taller blades so it resists warping more... my two cents on the matter. A 4inch tall blade that is 12" wide will bend easier than a 6 tall that's 10". But that's for me. Others make that shit work everytime. I just bend them, or they get warped in my drywall knives toolbag. Stainless for me. They all rust if you let em.
Try and get a taper to use durabond 90 first coat...
I do it on jobs that they want to he done asap first coat second coat it takes some skill to leave it smooth
@@abelpedraza299 I think he meant tapers who do piece work, wasting time cleaning your bucket every time you have to mix more is basically losing money
you should get some 12 footers no butt joints lol good job you should be a teacher best part you said walkaway let it dry a lot of people play with it till all of the mud is gone from wiping it to much. been in the drywall 42 years lol.
the guy at usg said to use mesh tape with durabond now i am really confused
He is also not repairing the drywall is he?
Dont use mesh tape. Only to fill large gaps in corners where the installer messed up.
As a novice I'm jealous how you make those nice even swipes when applying mud. Although I am comforted to see your hands are also covered in mud.
Mud while find you, and get on you like any crazy chic she will lay her mark on you... lol
Michael Block dirty hands, good clean money.
But there’s no glue it dura bond.
What did you use to transition between the Green board and cement board?
Thanks for the reply Drywall Doctor!
Actually another question if I may. In your experience do you find that green board holds up well in a bathroom environment when used for ceiling?
I see. I'm not convinced I was looking at the most up to date ANSI. I really appreciate the time and energy you put into creating this video. Quite selfless of you. Continued blessings and success in all that you put your hands and mind achieve.
This is pretty hard man I don’t get it after applying the tape
You just practice and you're probably pressing to hard the whole trick involves the angle of your knife and the pressure you apply play with those variables you'll be fine
It depends on how bad the butt joint is.
Ever fix the connection at the top of a sheet rock column where it meets the ceiling? My house has one and it cracks where it meets the ceiling as the ground rises and falls (yearly cycle in the midwest). No idea how to fix it.
Float the joint or use Magic Corner or X-Crack by Strait-Flex.
Is durabond 90 similar to Fastset 90 from Home Depot?
Similar, but synko/proroc 90 is sandable compared to durabond which is more on par with confill, basically a liquid cement, finish it nice or you'll be bald from pulling your hair out
Do u prefill every joint with 90 or just cause it’s in the bathroom
Everything everywhere
@@THEDRYWALLDOCTOR1 thank u.. love ur videos please keep them coming! Have a blessed night!
CZcams is watching me through my phone. I am doing this exact thing while listening to CZcams. Why would this be a suggested clip to watch? I haven’t searched anything about dry walling. Big Brother is watching.
Ryan Morrow
No doubt because CZcams is owned by google now
Make no mistake. Our phones are listening to us.
House is moved into every tape lifted.
Good explanation of why it happened.
Annoying having to replace every tape.
The house is about 40 years old in the UK
I just thought it was cowboys.
Means something different here my friend
You dont sand durabond its for fill coat
Hang on slooppy McCoys
Anytime I need a good laugh I watch his videos
you're missing some screws in the board...
And I was a professional supposed to do it
My butt joint is big and round. Is this correct?
No keep it flat 🤣😂
@@THEDRYWALLDOCTOR1 ok. Ill back off the hops.
My way of doing butts works at is best less sanding
Damn this guy is amazing, i dont know how he hides thats tape while its wet hehe i tried to do that and keeps exposing the tape heheh
