It might seem like a simple thing, how to mix thinset Mortar, just add some water to some powder and stir it a bit, wrong. Thinset mortar is composed of many things, and it needs to be blended and mixed with the appropriate amount of water, or other liquid, for the correct amount of time and then in many cases left to slake, and then mixed again. There is actually a lot of chemistry that goes into a bag of Mortar, and that chemistry needs to be activated the proper way to obtain all the properties it is designed to deliver. There is no guessing and no approximation possible to be sure to have the properties , workability, pot life open time and everything else that the thinset mortar is consistently every time. If you look at a bag of thinset mortar and read all the information on it, you will find a great deal of information, including the standards it is made to, the uses it is designed for and much more, including, how to mix the thinset mortar. Following the directions is important, in this video I detail exactly how to determine what the directions are and how to mix it to the proper consistency every time.

I was a helper for 2 years before becoming a full installer. 2 years of mixing thin set for the tile setters, I mastered it.
I Believe you. Keep up the good work!
Sal, your awesome and a legend.
As a fellow tile installer, with a lot of the same credentials and vision for the industry- your video's are a bible to anyone looking to learn
I appreciate his teaching immensely. Basically to follow the directions and donât think about experimenting with remixing to stretch your supply as it hardens. Thank you so much Sal!
Sal, one of the top tile contractors that is excellent instructing and explaining any aspect of the process! Great video!
Never done this type of work, but currently in the process of planning a DIY job of mosaic tile for my kitchen backsplash and you have already taught me a great deal on how to do it properly. Thanks for the upload and your expertise Sal.
Thanks Sal!!! With your help, my projects are coming out great. Thanks for the guidance and information!!!
Thanks for tip. I laid tile last night and I read the instructions first.
Smart move.
Thanks for all the professional advice Sal
You are absolutely right Sal, I recently realized this when I tried different mortar mixed the same way I usually mix my mortar, different products come out different thicknesses, whatever they say on the bag is a good starting point for sure, otherwise you end up mixing way too much mortar, I think a lot of the better quality thinset mortars are using water reducing agents, so the old mason's eye wont do you any favors because who knows how much of what each manufacturer puts in their different products.
I see you finally broke down and got this awesome drill.! I bought a Rubi 5 years ago and love it!
Thanks Sal. Been watching your videos for a long long time. I have learned through the years. Thank you Sir
Thanks for watchingđ
Best tiler I have seen on CZcams đđ»
Good video. Just what I needed to know.
Before starting all my diy projects. I watch several Sal vids in front of my prepped jobs before I start.Thanks a million.even if you hire a contractor you should watch to recognize rite from wrong during their work days.
Awesome! Thank you!
Very important information, great video Sal.
Great video. Just what I needed to hear. Thanks
Good video. Today I installed Strata Mat over plywood. I followed many of your helpful tips in the How to install Strata Mat vid, like using the grey thinset which made it much easier to see how much coverage I was getting. Great tip. Thank you. I mixed it only slightly soupier than usual for my first cut piece. Worked fine, but for the second piece, I mixed it a lot looser than I would usually, and it did seem to be easier to key in and spread, less toil. Even less air trapped, if any, and good coverage. I did not use a a roller, but a wooden float, and stepped all over it like Donnie D shows in his vid.
Great, best to do a little research for your first attempt so you don't get surprised.
Another informative video Sal! I admire your shop-vac attachment for getting rid of the thinset dust while mixing. Much better than holding your breath
Another brilliant video Sal.
Very well put! I have always said, when all else fails, let's read the instructions guys! The thinsets from most manufacturers will have specific times and like you said. I just had today used the large format & stone mix from same manufacturer and needed a 3 min mix then 5 min sleek then mix 1 more min then spread
Thanks for watching my video.
After 40 plus years, I still read all directions, whether it's wood floors, laminate floors, or tile floors.
Sal - Thanks for all your great information! I did a backsplash this weekend, my first attempt at tiling. My thinset mix and application was terrible. Mixed it a few times, added water, etc. EVERYTHING you said not to do. The next day I followed the thinset instructions to the T and the mixture was much more manageable and the result was a lot better ( and my wife and I are now talking to each other again). Thanks, again.
Maybe I should change the title to "Save your marriage: Mix mortar the correct way"đ
@@SalDiBlasi LOL
Another fantastic video Sal Thanks for all your effort.
I bought a digital fish scale I originally got for measuring fertilizer to put on my lawn. You just hang your bucket on the hook, tare it, then you can add your powder or whatever to make sure you have the right ratio. Useful tool.
Thank you for this tutorial Jay Leno!
No worries!
That vacuum attachment you used when mixing thinset looks to be very handy, specially if you are working inside costumers houses. đ
It also helps protect you from silica hazards
I use the wide head on my shopvac for dust control while mixing. Silicosis is an awful way to die.
Yes, ruining costumes could be very pricy in deed.
Love the vacuum attachment for the mixing bucket!
Me too!! amzn.to/3wNglNg
Thanks for the link. I'd already gone straight out to depot and and got a generic attachment I modified to sit on the bucket. Works great! Thanks again - you get a sub for that alone
My man said âfollow the instructions on the bagâ đ...big facts Sal. Iâm about to install some hexagon tile in my bathrooms (never laid tile before) so Iâm watching your videos
Thanks, take your time and get as much info as you can before starting.
@@SalDiBlasi is it fine to split the bag in half and add half the water?
I'm laying backer board in a small bathroom so I don't want to use a whole 50 lb bag
Man Sal, I wish I could work for you as an apprentice your knowledge is outstanding.
Great video. One addition.... inspect and weigh the bag before mixing. I have purchased bags that are up to 10# light in material from lowes. The bags were likely broken and re-sealed but many times you cant tell because they use so e kind of melting device to re-seal the bag. I couldnât figure out how occasionally i would mix a bag and it would be too loose. When I started weighing the bags before mixing it all became clear. The bags were occasionally short on mix.
Thank you sir!
Sal! Huge thank you for all of your videos. I have learned so much, and am currently putting in my own kitchen floor tile using Ditra. Happy New Year, and big high five!
You are so welcome!
thank you for another great video!
Thanks Sal, wish I had watched your video before I started a project, good information, follow the instructions on the package. ;)
Glad it was helpful!
Thanks Sal I learn all the right stuff from you buddy
Thanks for watching my video.
Ardex is what I use. Good stuff.
What's in the bag is alot of chemistry.never a truer word spoken.its not cement ,add water done.read the instructions on the back of the bag.cheers sal excellent video as usual
Get your tongue out of his ass weasel...
Hey man, New subscriber here. Just wanted to say thanks for making this video. Who would have thought to just read the directions. I did my first shower wall today and mixed my mortar the way you said in this video. Everything worked out nice with the help of a lot of your videos.
Good to hear đ
Sal how do you know what Paddle to use to mix up thinset - Does the mfg suggest a paddle type on the directions for the different types?
Great video!
Hey Sal, love the videos! What is that shopvac attachment you have that attaches to the top of the bucket to remove dust?
You can find it here amzn.to/2xjnerJ
HI Sal, How long is the thin set good for before it starts to harden after the slate process?
Very good information.
Thanks for watching my video.
Love the whale tail. Does work very well on the dust. And mixing mortar is more difficult than people think. The only other problem I have with mortar is taking in to account temp and humidity levels of the day using it on.
Yes good point, ambient conditions can be a big factor, thanks for the reminder.
I like the dust vacuum. Does the filter catch it. Mine just passes it through.
Thank you
Sal if your using polymers do you use the same amount as water.
Nice demo Sal .... thatâs what ur looking for ... consistency. Here is a thought based on my experience. A lot of times I donât need to mix a whole bag. This is what I do. Iâve found the using a ratio process. 1 to 3. I use a quart container and put in 1 cup / Qt. Of water to 3 cups / Qt of thin set. You can adjust the water if needed, but Iâve found this process works. Itâs easy to work out the ratio from the bag. Arden is just a different ratio Later
Many of the bags will have the ratio of liquid to powder printed on the bag, if not it he powder should be weighed and then the correct amount of water added. Seems simple, most manufacturers recommend mixing the whole bag because the contents can settle during shipping, they will recommend blending the powder if partial bags are to be used.
Like to share my experience as a first time thinset mixer. Yes, follow the recommended amount of water on the bag as Sal says. If you don't have a large electric mixer don't attempt to mix a 50lb bag. Nearly burnt my drill doing that. Buy a paddle suited to mixing thinset also. Paint paddles don't work so well. I suggest mixing a smaller batch at first. I found that 2 gallons of thinset to 2 quarts of water worked for me. You get about 3 batches per 50lb Versabond bag that way. Don't hurry if you use Versabond, it does not harden for hours in the bucket. I know Versabond is cheap thinset but it's what HD sells. You have to shop Lowes if you want the better Mapei product.
Took a tip from mixing pizza dough and added the dry to the water in two parts.
Having the correct tools is essential. however different types of dry set mortar require different amounts of water, by this I mean some require a higher ratio of powder to water than others, in some cases quite significant.
What happens if you use a 450rpm drill instead of the 300s? Does that compromise the product?
I notice a lot of guys use the 450s. The rigid and the dewalt. Idk why they dont add the ability to change rpm.
Whatâs the best thin set to use if you just need to make smaller batches?
Fantastic!
Great sal,this is one of your best,informative videos,who makes the vacuumed attachment, for dust,who makes the dog bone uncoupling membrane, interesting about ardex wanting you to use they're paddle, I'm not familiar with that one,I've been recessing,the slab, for preslope,foam to linear drains,keep em comin, your the best,mom and I are subscribed,and enjoy learning
Thanks Sal. Your videos set me straight. Unfortunately after ive already laid the floor but i think it will hold up for a few years atleast. Used way too small a notchđŹ.
Im about to lay the subway tile (3x6) on the walls and thanks to you they will be properly installed and last a really long time. Thanks again
Well now you will know for future projects, hope your floor lasts longer than just a few years.
Since I need to mix much smaller amounts of thinset to use at a time I convert the water to mortar ratio into a rate. For the Mapei lft it is something like 250-270 ml water per kg of mortar
Hi Sal, thanks for the video. Would you suggest premix buckets? I noticed they are two to three times more expensive but then no mixing...?
No absolutely not. I would not use that stuff if the paid me to use it.
@@SalDiBlasi Not the answer I was expecting. I will stick to the bags. Thanks!
how do you like that Rubi mixer? Looks sweet. Bet it sure beats my 3/8 drill. Can you select the speeds? what are the rpms of the different speeds?
Love it, here is a link to a video, m.czcams.com/video/pvS920usoFk/video.html
Man, if I wanted to read and follow the manufacturer's instructions, I wouldn't be watching how to videos on CZcams! HA! It always kills me how people who aren't engineers think they can engineer something better than the engineer who engineered it! Great video!
One thing that most people get wrong and then complain it doesn't work like it is supposed to is thinset, this is for those people that ref to read directions.
@@SalDiBlasi You had a bunch of other great tips in there, too, like don't add more water when it starts getting stiff.
What's the bucket attachment you have for the shopvac? That looks amazing!
amzn.to/3HfkvlC
Hi Sal, big question: does thinset GO BAD, get stale, or whatnot? My boss bought some of the basic grey CustomBlend from HD that comes in the paper bags. (I personally only buy Mapei because itâs sold in impermeable plastic bags.) Itâs been sitting in a garage for a few months, unopened.
So, I mix it soupy, and nevertheless the stuff immediately starts to get dry and brittle BEFORE Iâm even done buttering the tile.
Is it possible that humidity has seeped into the bags and messed with it chemically?
Thinset has a shelf life of about a year, it will go bad, especially if it is left in a damp space. There should be a manufacturing date stamped on the b bag, look for it and see when it was made. Best to dump it if it is firing off that quick.
Where can I get the curved vacuum attachment you use for the dust collection? Thanks
Here is a link amzn.to/2XMvtIs
A question I wrestle with when tiling is knowing if I need a particular Thinset for a job, or is Thinset Thinset as long as its mixed according to instruction? I am a DIYer that mainly does tile floor and bathroom shower/tub surround tiling. If I am doing vertical tiling (wall) is there a Thinset that holds tile better in place when gravity is fighting it?
czcams.com/video/S80GVg4Y4MU/video.html
I mixed my adhesive for not long enough, just with a fork (cue laugh...), and probably added not enough water (for some reason I thought it should be quite thick but seeing your videos, I think mine was way too thick!)... It's just a very very small area (fireplace hearth) that won't really be walked on, just decorative on the floor... the tiles are stuck solid, but should I be concerned? Will it fail over time do you think? I used NX flexible standard set adhesive from Wickes in the UK. Definitely a botch DIY job here... but I just wanted to know if you'd rip it up and start again or just leave it and grout now?
I would wait and see, especially if it only decorative.
Great video! Where did you get the attachment for the shop vac for the dust when you it the powder in ?
amzn.to/2YrNMUE
My mom just had some pavers replaced, and the people put Red Bull in the mix, then put the new pavers on (which by the way looked worse than the pavers before). So can someone please tell me if there is EVER a time when Red Bull is used in the process of setting thinset?
HI Sal,
Have enjoyed and furthered my education with many of your videos. Quick question............,
Occasionally I only need a partial batch of mortar. How do I get the right consistency if the directions are written for a full bag?
Nevermind............should've trusted you and watched the rest of the video first :)
Can you do a closeup on the way you butter tiles so that the thinset doesn't squeeze up between each tile.
Have you ever used the collomax mixers? If so whay do you think of them are they worth the money?
Sorry, I have not
Hey Sal, Its been asked a couple of times already, but what is the name of the dust extraction thingy on the bucket?
or is it home made?
Cheers Sal đđŠđș
How about a link amzn.to/2pF3IlN
Sal, love the videos. Can thinset go bad? I have had a full bag for a year and a half. Never wet, is it wise to use it?
Thinset has a self life of one year. If it is expired, then toss it. Does not make sense to risk an entire job for the cost of a bag of thinset.
Hi Sal the fibreglass Weni board with foam in the centre. How do I fix wood to this so I can start my first course of tile. Also what size notched trowel do I use to fix 250mm x 500 mm 8 mm tiles to fibreglass board? Cheers Dave
Screw through the board into a stud, then seal the hole when you remove the ledge board
Sal DiBlasi yes managed to do this. I placed my batten 2"X1" over the longest part of the wall then fixed into the stud work. As I'm new to all this I managed to get a slight variation going off 90 degrees to the next wall. I found my tile spacers were slightly out at the gap. I never knew tiling could be so tricky to do. I also learned that if you push slightly more on a tile than the previous, you start going into the wall and your levels starting going out. Also lightly scoring the tile on the machine helps with a cleaner cut too.
How many 55lb bags of mix do you make.? I'm doing a 36in neo angle shower pan
Sal I'm in your area. Where do you find Ardex x77?
Closeset to me is in Woburn www.google.com/search?q=belknap+white&oq=belknap+white&aqs=chrome..69i57j35i39j0l4.6231j0j7&sourceid=chrome&ie=UTF-8
Sal, the vacuum attachment is it available online? I have never seen one but now I know what to look for next. Thank you for sharing your knowledge
amzn.to/36NMRSW
I would be interesting to know your thoughts or the though process when you look at tiles and how best to plan for working with the or if you have Customer's who ask your advise on what to choose and what not to choose.
That's comes with lots of experience sal would be a great person to answer this
Hi Sal,
when you make spaghetti aglio olio e peperoncino
do you add first the garlic or hot pepper to the oil ?..
Let me ask my wife, she does the cooking.
Hi Sal- Thanks for sharing all of your knowledge. It's really helped me along the way. However, I made a mistake the other night. I mixed some Ardex-5 once, and only let it sit for 5 minutes before laying it down. I did not mix it a second time. Now, it's too late. It's hardened up, sitting in between Ditra and subfloor plywood. How concerned should I be? Thanks in advance!!
-Kex
You're in luck, X5 is one of those few thinsets that don't have to slake, mixit and go.
Sal you are a god sent thank you! So You mentioned even the paddle can affect the thin set and I see you are using the spiral type. I noticed that most of the thin set shows an egg beater on the package. What is the advantages/disadvantages of egg beater versus spiral?
The spiral is specifically designed for thinset, the egg beater is an all purpose mixer.
Sal, with Schluters All-set, they claim that you can install porcelain tile inside a shower on top of the Kerri. Was wondering if you had done this in the field yet. Even though schulter says you can do it, I have hesitated to do so. Can you shed any light
Yes many times, they make their thinset to work with their product, so you can use it with confidence to set your tile over Schluter products..
Which mixer speed do you use?thx in advance
I will usually use the lower speed.
Sal is it possible to over mix the mortar? Regards.
Not sure about that.
What's your thoughts on tubs of Mapei ready mixed tile adhesive? I have just tiled a small bathroom floor for the first time using mapei and I found that the adhesive squeezed up between the tiles. I was told to use a 4mm trowel and I thinly back buttered each tile. How can I avoid the adhesive between each tile? I aim for 100% coverage by collapsing the notch lines.
Stay away from the pre mixed stuff! If itâs a 12x12 tile, use 3/8 trowel. Any larger, use 1/2. Many installers scrape away about 1/2 of thinset against existing tiles before laying the next one to reduce oozing out. I use the non-pointed edge of a painterâs tool. You also might be pressing down too hard or the floor isnât perfectly level.
a margin trowel trowel also works well. swipe with the trowel against the side of the tile next to the one you're installing. Also, make sure your thinset is the right consistency. Too soupy and it will tend to ooze up and out.
Thinset in a bucket is just mastic with sand, I stay away from it even when it might be an occasion that it would work, which is very rare. Directional troweling correct trowel size, proper thinset mix and technique will help with reducing the amount of thinset coming up the grout lines. the comments before mine make some good points as well.
@@SalDiBlasi Sal, you messed up a prime opportunity to say, again, "put down the bucket." Haha
Hi Sal, would you consider doing a video on how you decide upon which thinset mortar and trowel to use for a particular job? In particular, LFT verses regular thinset, and flexbond thinset. I've read the manufacturers guidance, but some of their guidance is confusing, like when Mapei says Ultraflex LFT is good for any size tile. So why do they make other kinds?
This might help czcams.com/video/BJoPHGtukqo/video.html
I am an old lady, mixer tool is too heavy for me. Can I mix 1/4 bag each time with my steel rod manually? I will control the water ratio very well, just no strength to mix big bucket of material per time. Please help
Latecrete for life!!!
Is that an uncoupling membrane you're setting on? If so what brand is that?
Good info Sal...details...details
Here are all the details czcams.com/video/s9lpR6_TRB4/video.html
Hi Sal, I mixed my thinset the same way you described here, but after 48 hours some of the tiles were coming off and the thinset was still a bit moist. Do you think I should have given it more time to cure considering it was in the basement room where the temperatures are around 67 degrees? Thanks!
Can't really say what might have happened without actually seeing it.
@@SalDiBlasi So you would not have any idea why the mortar was still moist after 48 hours, and what the actual cause of it was. Maybe I put the trowel lines the wrong way for poor air flow. I put them running from wall to wall instead of towards the entrance and exit of the room? The air conditioner has been running overtime in our home, but I only set it at 70 degrees, but suspect in the basement it is a bit cooler.
@@SalDiBlasi I did use 1/4 inch trowel to do the small job. Maybe what I did wrong is that I mixed flexbond mortar with a polymer modified one step mortar that I bought from another hardware store. I was running short, and sprinkled half a cup of flexbond into the mix, and the flexbond was an older mortar that I left in my furnace room for the last 7 years. Maybe that is the problem because the first half of the room was done only with the polymer and they seem to be okay? What do you think
Very handy vacuum attachment. I always do the same when mixing indoors.
You can find it here amzn.to/2xjnerJ
How long will it take for that bucket to set up on me though? Iâm always worried about that and Iâve definitely never mixed a whole bag at once
Keep a damp rag on top of your bucket helps alot
Awesome video! But Iâve a question. How about if you going to use half of the bag or less, how do we should measure the water etc? Thanks
Mix the correct ratio of water to powder.
All set recommends to mix at 300rpmâs... do most mixers have rpm settings? Does this matter?
That is why I use a mixer designed for thinset
Hi, can anyone suggest the a adhesive material to have a perfect bond between two cement boards
Use urethane adhesive for wood floors, use a vnotch 1/4 x3/16 trowel, bostick
Mud
I have some 317 laticrete that has been in my house for 3 years it appears to be in really good shape but I believe it has a two year expiration date would it be okay to use if it's in good shape and has been in a climate-controlled area or should I throw it away and buy a new bag
Throw it out, do you really want to risk an entire floor to save a few bucks.
@@SalDiBlasi thank you
0:28 we gonna mix this according to directions. Roll credits
What's the ratio of water to powder? I don't want to mix the whole bag.
Can someone tell me what speed on a six speed mortar mixer tends to be best for mixing at 300 RPMs under load? Thank you
The speed will be printed on the bag of thinset.
@@SalDiBlasi thanks Sal. I understand itâs supposed to be 300rpm, but I canât find anywhere on the bag where it says what speed a typical 6 speed mixer should be on. Itâs Schluter all set. I would imagine you have a favorite speed for mixing at approximately 300rpm. Iâm sure itâs not speed one, but I would guess itâs not six either. Thank you.
I was mixing All set - schluter and my drill started heating up on lowest rpm..and battery died. Thinset came out peanut butter ..but not as creamy. So, have your tools and standby tools ready.
Also, sal, what is your opinion on the premixed mortars?
Premix is Mastic, mastic is junk.
@@SalDiBlasi Thanks. I just bought this Mapei Ultraflex-1 thinset for my porcelain tile over ditra mat. Will this work? It looks like its a modified thinset.
Your clean in the way you use a vacuum, I use the same attachment , but always finger wipe the paddle. Just banging it off and spinning in the bucket creates a very nasty bucket at the end of the day. Now getting rid of that nasty slurry water is a problem and most guys just chuck it on the grass. I at least like that you take it out of the water bucket, because that's an accident waiting to happen. I dont use your particular drill and paddle , but after I mix , I then first release the paddle from drill , tap the mud off in the bucket, then finger all the mud from paddle before putting just the paddle in the water bucket. At the end of the day my paddle bucket has no nasty mud in the bottom....I know it's a small thing and most would think I'm nuts, but I cant stand a nasty water bucket at the end of the day that can ruin a lawn or that you have to scrape out.....love the direction video however, definitely should be flollowed
What's the best way to keep tiles level? First time tiling. Any tools or tricks to use? Also, how do I keep an even layer of thinset mortar when installing?
Get leveling clips.
Sal how about feeding the thin set slowly while you're fixing it??
I find the thin set gets mixed better that way..
Glad to see you clean your paddle when your done, ardex school said basically what you're saying asked if I can fan dry ardex they about had a heart attack the answer is never
Ardex academy in Pittsburgh, was there a couple of years ago, very informative, you will always learn something any time you go to a training event, be it NTCA, Ardex, Mapei, Laticrete, Schluter, you name it
@@SalDiBlasi thank you for all your hard work and info
