I'm in the process of doing over my shower but don't know how to put the tiles in the shower
How do I put tiles on an uneven concrete floor ?
@@user-ux2yz2ch2y With great skills and magic. I offer a phone consult service should you need help. See above.
Very informative, direct and to the point, ......less hype ,more basic down to earth advice, delivered by an experienced builder.....
Thanks for the video between helping a friend last week do my shower and your
video I felt confident enough to do my basement bath floor tile.
Things went well , got the whole family involved ,and after my next step of adding
a 4 inch kick plate and grouting I think it'll look sharp.
I watch a lot of your video's as I try to learn to do it myself, thanks,
That is a good tip, especially for tile that has a matte finish on the underside. Thanks for sharing.
Great question! Because my old one is in Cincinnati, OH at my other house. I need it there for a project that starts in two months.
Thanks for the wet-floor-first tip. I laid 33 tiles, replacing tiles laid by a professional, which had not adhered.
Moistening the concrete, and the back of each tile, as recommended in a posted comment, really paid off. Every one of the tiles adhered. Every one.
Thanks, again.
cant you just vacuum the floor?
Try it. Then wipe the spot you just vacuumed with a damp paper towel. Tell me what color the paper towel is.
Great question to ask the Thinset manufacturers!
Absolutely brilliant video. Thank you Sir.
You're most welcome. Be sure to sign up for my FREE Newsletter there. Also, be sure to Subscribe to this channel. MANY new videos are coming out soon. Finally, be sure you use the cement paint when you do the overlay. PRACTICE first. Do a small section to get the feel of how to work with the overlay. Spread the word about Ask the Builder!
Using a knee-pad is a great idea! I have exactly the type of knee pad you are using. The hand-holds allow you to get up more easily. It becomes a seat if you turn it over, with the hand-holds becoming the legs of the stool. It was given to me by someone who had no use for it. Seeing you use it, I'm so glad to have received this "vintage" item to do my tile-setting project.
it is good but don't use it anywhere that you can slip, it's just metal....no rubber or anything. i want to say there are suppose to be rubber feet for it but his nor mine have those.
i slipped trying to get up with just water on concrete, it was horrible. put down anything, a old towel or something to give the legs some grip.
Awesome video! You did a great job at demonstrating
Thanks !
Great video.. although my tip would be to lay your thinset with the strokes going in the SAME direction. It is proven that when the tile is pressed down, the thinset will cover the most surface area on the tile. In end, making the tile less likely to crack or break. I hope I could help ;)
The issue with the direction of the thinset lines is complex. It depends on the pattern on the underside of the tile. It's best to defer to the tile manufacturer should they have written instructions for exactly how to spread the thinset for a given tile.
Doesn’t matter with the uncoupling thinset he’s using.
There os no complexity - the point is that the lines have to be in the same direction, as per this video, which every tiler should watch:
m.ruclips.net/video/Way5bMh-eYg/видео.html#bottom-sheet
Good starting point. Like he said many more details for a good installation. Always back butter the tile for the best adhesion. The correct trowel notch for the particular size tile you are using is important for the correct bond to the floor. The bigger the tile the greater the amount of thinset under it there needs to be... to keep it simple.

Water is a great idea! I have used it in between layers of stucco on a wall, and it makes a big difference in how the stucco adhears and dries, and minimizes cracking. I hadn't thought of it for tiling, but it's the same principle.

Great demonstration!
wonderful. you explain with passion. Thank you so much.
You are a great guy
just invested in some snickers duratwill work trousers with built in kneepads and would highly recommend if you spend much time on yer knees good vid thanks Tim
its needfull and usefull, thanks for you and for your support team if you have.
Yes. Make sure the floor is clean. You better go to my AsktheBuilder website and read ALL my past columns about installing tile.
i love your videos! and for some reason i also love when you finished applying the thinset and it made that cool pattern hahaha
Thinset is not supposed to have cool pattern for best coverage. It needs to be straight rows.
Tim,
I made a suggestion previously. Here is another. The more parallel your lines of thin set are, the more air that can escape. The way you are doing that, there will be areas where air will not be able to escape. Try this. Take a 1 foot square of clear plastic should be sort of thick. Make your lines completely parallel and drop the tile on it. Then slide it with the lines, then against the lines. You will notice there is no air under... Try both ways and see what ya get...
thanks Tim 👍🏻
Thanks, Tim!
Thanks Tim.
I had difficulty how to spread the thin-set you made sound easy . of course I need hand skill and practice plus natural dexterity. I am putting in 18 inch , filling back of tile. Took me a while to learn how to fill the tile back fast and clean.
Still can not do it clean.
I think i got it from your instruction : how to spread the thin set.
thanks millions.

hey thanks for this video. i'm about to do my entire kitchen today in ceramic tile
How did it go?
I saw another video they put morter on the tile too. I started this technique and it's crazy labor intensive. Wish I had seen this 1st.
It's a complete waste of time to back butter. The old tile masters didn't do it. There are millions of square feet of tile installed that are not backbuttered. It doesn't solve the ROOT CAUSE of failure and cracking!!!
The ROOT CAUSE is a substrate - the slab - that is NOT IN THE SAME PLANE. The old tile masters rodded their mud base. They didn't pour directly on top of concrete slabs. The mud base was in the same plane with no humps or dips. Thus, when the thinset was evenly applied to the mud, the tile BY DEFAULT would have 100 percent contact with the thinset with no voids.
I'm trying to do my best to destroy this insane myth about back buttering. You said it well - it's crazy labor intensive.
Another great video!
USG makes a self-leveling underlayment compound for this exact purpose.
Great tip on damping the concrete before the thinset. This same rule applies putting the 2nd or 3rd coat of drywall mud over freshly sanded joint compound. The fine dust will prevent the new layer from sticking well and could chip off.

Thanks for the video!
Yes that's correct. Just follow the written instructions that come with the membranes. Usually sold at tile stores, NOT home centers.
Good advise...
Wow Tim you really get excited spreading thin-set... Good for you :D
hahahahahahahaha
Lol Yeahhhhh
I feel it! I did my first floor tile job a few months ago and sold the house, can’t wait to buy another and do some more tiling. It’s hard ass work, but there’s nothing more rewarding than tiling a floor
Thanks for that tip!
I recommend that you either read all my ceramic tile columns at my AsktheBuilder website, the dot com one, or you schedule a 500-Second phone call with me. At my website, look at the top. See the Shop icon? Click it. Look for the Consult Tim category. Good luck!
Thank you Tim for the reply..and you are absolutely right about defective tiles.
I had not thought about them not being the proper size..And i like the grid line idea.
Best wishes
Great work sir.
Many thanks. Speaking of that, click the *THANKS* text link and see what happens.
This is exactly what I'm doing. Clean concrete (no bumps, no previous floor paint and filled carpet tack holes) and applied thinset then ceramic tile. Looking at all these videos confuses me. Some are saying to primer floor before tile yadada. I'm keeping it simple like this video so I hope I don't regret my work.

Yessir. ive been a suscriber for some time now. i enjoy the vids. if you have a video on Topical Vapor Barriers where there are vapor issues. i would love to know. thanks again!
@echtconservative I've done it both ways for years. In this case, I chalked lines every three or four rows to ensure I was running straight. It's best to use a combination of spacers and chalk lines in my opinion.
thank you good information
If you want a crack isolation without any added thickness, use redgard roll on membrane, although not as good as a uncoupling May, it will help with crack isolation and will allow for some flex if the concrete cracks.
I have to disagree. If you roll on red guard to 25 mms,it is as good if not better than any other product. For the simple fact that it's more rubberized. Still great knowledge on your comment. I just didn't agree with the not as good part. Lol have a good one

Thank you, this was helpful.
Happy to help. Join my Discord: discord.gg/u89GyDjBdr
Tim, one thing i would sugest is that i would also wet the back of the tile also. is there an adhesive that also seals the concrete so moisture and mustyness cant infiltrate the room? . thanks, jeff
Go to my AsktheBuilder website when you have questions. The dot com one. I have columns there about concrete overlays. READ each of the columns. You do NOT have to rip out the concrete.
Very Sound opening in advice concerning knee protections
Yes, I should have done more over the years to protect my knees. Way back when, we didn't have the fancy kneepads one can currently get. Look at some. They're amazing: amzn.to/3CMd85u
I have some great columns at my AsktheBuilder website about vapor barriers. You want one that meets the ASTM standard I mention. Just use the search engine at my website. MORE videos are being uploaded very soon.
Great video! I've seen a lot of people putting down a board first and not direct to the concrete, when is that needed? I am doing a kitchen and dining area soon and would like to do it how you've done here, great method!
You should also wipe the bottom of the tile to make it damp before you place it on the thinset in the same way and for the same reason you wipe the floor it makes a stronger bond.
I dip mine in water sometimes
Do NOT do this with porcelain tile. It will not adhere to thin set if the tile is wet at all.
Great video. I'm currently working on a basement project in which i've decided to take on the task of tiling it myself. My friend recommended that i lay down some self leveling concrete over it before I tile. The floor is pretty level and i thought the thinset would take care of any small divots. What do you recommend?
Thanks! Please help spread the word about them.
your so wonderful thank you

@speezguy Could be hot tar. It's not easy to remove. Chip it away with a sharp chisel.
thanks!
@akmrmike How about it? You've got two choices: Get some and test it doing a video of the process. Or, you go to my AsktheBuilder website, the dot com one, and click Shop. Once there, you find the 15-Minute consult and I share with you my skills and magic.
Thanx for the video. It was recommended to me to put plywood down underneath the ceramic tile to make the floor level. What do you think? Personally your way is a lot easier
Another great Video Tim, keep up the good work!! Does ThisOldHouse know you stole their theme music? lol
thanks for the video. i like to know if this technique appliess on smooth concrete. i am about to start tilling my basement floor and i wonder the smooth slab is going to be a problem. if this is a problem, what you recomment?
The Man the Myth the Legend 🤙🏼
In my best Elvis voice, "Thank you...thank you very much."
Hi Tim,
i am getting ready to lay some tile on a concrete bathroom floor and my question is..when to i install the little plastic spacers? do you do it as you lay each individual tile?.
This is going to be my first time doing this so i am watching your videos to gain experience.
Thank you, very informative videos.
Does crack isolation membrane offer any warmth? My brother is concerned with the concrete slab/ceramic tiles being too cold during winter. Thank you
Mr. Carter,
What if i have a problem with water vapor/moisture in slab? i think my house was built without vapor barrier underneath the slab. sorry if i missed that in your video. thanks!
Go to my AsktheBuilder website and read my columns about epoxy crack repair for concrete slabs. Then read my columns about self-leveling floor compounds.

If you wet the concrete floor that way, you also do not need to buy modified thinnest in some cases. The modified stuff cost three times more money. All it does is have a latex polymer added to it to prevent premature drying after it is applied. In the case of concrete. If the concrete is dry and you apply unmodified thinset it will absorb the water in the thinnest before it cures. So, what I do is hydrate the concrete well enough so it has no way of absorbing the water from the the thinnest. I save hundreds of dollars this way. With no issues.
That's exactly why I sponged the floor. To remove dust and to slow down the suction. You might want to read all about the hydration chemical reaction of cement on my www.AsktheBuilder.com website.
Uh, yeah.... :->>>> I show in the video applying it to a concrete floor. On your monitor does it look like wood? I'm asking as I thought it was very obvious that the substrate was concrete.
Good stuff.

Very good video. My only quibble is that you need to get as much of the thinset out from between the tiles as you can before you grout, or the grout may not be deep enough to hold properly. It may crack or otherwise come loose. May not be as important for fresh tiling an entire floor but might be an issue where you a replacing a broken tile and can't get all of the old grout off an existing tile without damaging it..

Rarely. Usually out of the box they are squeaky clean.
Five Stars!!
I have removed ceramic tile floor and I am having a very difficult time getting the thin set off the concrete. A scraper was not nearly able to remove it and then I tried a hammer and concrete chisel. This was nearly impossible too. Any suggestions?
Thanks,
Jim
I recommend we talk on the phone. Too much to type. Go to my AsktheBuilder website, the dot com one. Click the SHOP icon at the top. Once there, find the 500 Second Consult.
I install them vertically and remove them just before I grout. Frequently I'll not install them just chalking a grid of lines. If the tiles are cheap and not the exact same size, the lines will NOT be straight with the plastic spacers. They only produce straight lines if the tile is perfect.

ALWAYS back butter the tiles with thin set. That will make sure it is a 100% bond. Its especially important with porcelain and stone.
Hi, what exactly is back butter? and thank you ...
@@favour8194 adding an extremely thin layer of thin set directly on the tile before placing it down.
Thanks for that demonstration, Tim. If you allow some expansion room on your edges, do you have to be very concerned about expansion joints in doorways if you're tiling about 300 square feet? I don't have any expansion joints in my concrete slab and I don't have cracks in my slab. Also, I want to tile and then put in a small kitchen cabinet over the tile. Is that okay to do it that way?

Great video.. thank you. I am preparing to tile my smal bathroom in my basement. I noticed you did not back butter the tiles...I have seen others swear by this. What are your thoughts? Thanks ---
It's not necessary. Recall your high school physics class about tension and compression. What happens to tile that is under tension? READ THIS: www.askthebuilder.com/ceramic-tile-crack-prevention/
Buttering can be a huge mistake. Any void spaces under the tile lead to tension when loaded with weight. Too much weight and you get cracks. Had you installed a self-leveling compound so the entire floor was in the same plane before you started, you could have spread the thinset as I show in my videos. Spread evenly the tile floor would have been perfect as the tile would then be parallel with the leveling compound.
Can I use the same method on cement floor?
If back of tile is not flat you can flat trowel thin set to fill indentations on tile. Very good .

OK, there's no problem with the tiles, they aree clean (if new) but what about the mastic residue left on the floor after pulling up linoleum? Is it a problem if I don't get it completely off?
I watched this video to see if I was doing anything wrong especially since what I bought is thinset pre mixed. Great tip to moisten the slab, I'll start doing that, as I've already finished a third of the project. One thing you did not mention though is to butter the back of the tile with thinset too. Otherwise great video , thanks.
Thanks. I'm afraid you've been victimized by the Back Butter Gang. Can you explain the science behind their method? Do you know about tension forces? Does back buttering solve the tension issue? If so, explain in great detail how it does that. The old master tile setters NEVER back buttered. I know as I had the luxury of interviewing one about 50 years ago. He was setting tile before World War 1. Your question should be: Why did the old master tile setters NOT back butter???????
@@askthebuilder I have no clue, I'm a rookie. I figure there might be the possibility of less than 100% coverage, so back buttering ensures that in my perception. I know when I misplace the tile, lifting it back up is difficult so I think the tension is there good. I'm a err on the side of caution guy, so thats the way I favor. I will though take your advice and wet with sponge as I had noticed even after sweeping and blower that there was still dust present.
hows does this thin set compare to Versa Bond??
superb
YW as we say in Morse.
You could put a crack membrane down. I don't know what you use, but put a coat of Mapelastic HPG on the cement and you would never notice it in the height difference. Second if your going to put directly on concrete it's best to score that concrete with a crisscross pattern using a grinder with a diamond blade at least. Just some ideas
I hate to tell you this, but thinset is rated for wood floors. You're correct about wood being hygroscopic. Just follow the guidelines set out by the Tile Council of America. They approve tile over wood if you do it the way they say.
Great video Tim! Just subscribed and gave you a thumbs up!
Getting ready to tile over some epoxy with acrylic flakes in my shop that's being converted to a casita. How do I prep for thin set over epoxy?
Thanks so much!
Aaron Smith You make sure the epoxy is bonded. If you're going over a slab, you may want to use an isolation material. Let's see if this link to it works: amzn.to/1ULmlwB
