    A friend of mine who is a Tilesetter, did my home 20 years ago. He used the hardy backer board and just screwed the boards into to the plywood floor. Then installed the ceramic tile. About 1 month later..immensely loud noises occurred around 3am. I woke up and thought someone was firing a gun outside ( Yes it was that loud). I look around the kitchen and the whole floor was cracked along the grout lines and whole tiles. I told him what happened and he said " That never happened before and has done 100's of jobs with no problems. So now I know he installed it wrong and thus, ends the mystery. You have more knowledge of this business than anyone I met or saw on UA-cam. Thanks for another great video and hope your doing well- Blessings.

    New Construction.. Saw a guy staple down Ditra. That’s it. I service their hvac so I need to do a “bathroom break” sometime and check how it’s holding up.
    Doing my addition with durock by following the manufacturer instructions. Boy you are right about the labor. But the savings was worth it to me. Hope I don’t have any regrets.
    Thanks for the tips, hoping for a good finished product.

    Being said, would never use any of that on a bathroom floor.
    I think when talking about deflection we forget most bathroom floors are 5 x 10 or less. I make sure to glue/screw down 3/4 ply & then bond the backer board.
    I use either of the liquid membranes available at the big box stores & waterproof the entire bathroom floor.
    I don’t care if an elephant stepped on that floor- it ain’t deflecting

    Great video, Sal, thank you! I'm a young tile contractor in Colorado and have learned how to do basic tile installation from my dad, who is a custom home builder. Everything more complex, such as pouring a shower, installing Ditra Heat, etc. I have learned from you. I'm always open to trying new methods to get the best results. I just installed my first heated floor this week and while I must say that it's relatively labor-intensive, it's a great product that I plan to use more often.

    Sal, that was PhD caliber knowledge from a guy in blue jeans. I appreciate it! One burning question I have is what is the practical outcome in the tile flooring when shifting/settling occurs in the structure after using backer board? Grout failure? Cracked tile? Tile separation from backer board?

    My favorite way is to prime the floor with red guard, staple lathe with a wide crown staple overlapping them. Then use a cement mixer and pour self level as thin as possible. I've went back to jobs that are 15 years old where I put on an addition with big 12x24 tiles and absolutely 0 cracks anywhere.

    Sal, thank you for another helpful video. I had a tile contractor look at my bathroom floor to give a quote. I told him I wanted Ditra uncoupling membrane used over the subfloor. He saw that I had Advantech flooring which the floor has no flex whatsoever. Rock Solid. He proceeded to tell me that Ditra over Advantech subfloor is a big mistake because if you ever go to remove the floor, the floor would peel right up like nothing. He said Ditra will not stick to Advantech flooring and that if I wanted Ditra I should have put down a plywood floor because Ditra will stick or bond to plywood. Is this guy all wet?? Ive had other tile contactors look at my job and recommend Ditra. What Gives??? Thank You Sir

    • @SalDiBlasi

      I guess all those hundreds of job that I have installed Ditra on Advantec will all fail. This guy probably wants to sell you cement board and is using it as an excuse to scare you. Just be sure to use AllSett which is Schluters high polymer content Mortar which meets ANSI A118.15 and also use Either AllSet or Set, their unmodified mortar, to install the tile, and you can get a Schluter Lifetime warranty. Here is one I did over Advantech some years ago, Allset was not on the Market so I used a different A118.15 mortar. ua-cam.com/video/GXqjLGTwbnM/v-deo.html

    The beauty of the ditra is in the inverse egg carton design . The thinset is in the 'nests' , never attaching to the Ditra by surface contact but by a 'Velcro' like attachment . Think of LEGOS that snap INTO the adjoining surface . The thinset is surface attached to the tile back but the Ditra can move horizontally , not forcing the tile to move with it . Hardy back , cement board , dense shield are ONLY for a better base than drywall (including the green junk) ON WALLs only .

    Still feel more comfortable with fibrerock board with LFT mortar and screwed every 4 inches with screws every 2 inches on the seems. I don't like reinventing the wheel if it's never been broken . Never had a problem with either, but personally, installed correctly my tear outs I've done over the years (older jobs from others) the tile was insanely stuck with fibrerock. I live in northern ontario and it gets cold here , alot of movement every year and I've seen more fails with ditra. Just based on experience and time telling the tale. Maybe because some don't know the proper way to install ditra , but with what I've just described , why reinvent the wheel and throw everyone off.

      I just don't like the use of plastic materials if it's not necessary. I love levelling clips and use them on very large format tiles , even then, such a large amount of waste is formed by them. I have the same coffee can of spacers from Last year still going strong ,and use the same ardex rover mixing system to self level my floors for the last 7 years since I bought it. No waste . No plastic on my local landfill . I also build mosaic coffee tables on the small amount of spare time I get with most of my tile waste.

    In NZ we have Hardies 6 millimetre thick tile and slate underlay which is a fibre cement sheet .the installation instructions are to use cartridge adhesive like nail bond and flathead galvanised nails at 4 inch centres nailed over the whole sheet. I have laid hundreds of sheets over the years,in theory the nail bond acts as an uncoupling I guess and the tile and cement sheet become one.

    I did a little bit of research on Hardie products, and I was shocked at how hard they fight customers to deny warranty claims. Their argument appeared to be that their product was flawed by design, but was not defective in materials and workmanship so the terms of the warranty should not apply. From what I saw, the courts side with Hardie basically every time. Don’t buy a Hardie product for the warranty unless you have an army of lawyers.

    My only concern with using an uncoupling membrane over concrete in a normally dry basement, is even if any amount of water were to find its way into the dimples of the uncoupling membrane through the side or perimeter edges, it would never be able to dry out.

  • @nekomancey4149
    @nekomancey4149 5 років тому +1

    Question Sal as I get different opinions on this and haven't located the answer in the TCNA handbook (I'm sure its there I just haven.t found it). Installing tile over perfectly level concrete slab foundation subfloor. Do you waterproof/seal/vapor barrier the concrete slab before installing the tile? Obviously an uncoupling membrane is optimal in every situation, but if the customer doesn't want to spend the money on ditra or the like, do you go directly over the bare slab or prime/seal it first? On the one hand you want the thinset to permeate into the concrete slab and back of the tile to promote a strong bond, on the other hand I can see situations where you would want a vapor barrier. Thanks as always!

    • @SalDiBlasi
      @SalDiBlasi  5 років тому +2

      If you want to go directly over concrete, then that is fine, however you want to be sure that the concrete has no sealers or bond inhibitors on it. as long as there is no standing water, most times the concrete can still be tiled. Do a water drop test on the concrete, if the water absorbs into the concrete quickly, more than likely the pores are open and suitable for thinset to bond to it, if the water beads or takes a long time to absorb into the concrete, it will need to be scarified in some way to open the pores. If the concrete is below grade and has some amount of moisture coming through, I would think very carefully about just tiling directly to it, not because the tile will not bond, but because the moisture needs to be managed in some way to mitigate all the possible issues that can arise from the moisture in the slab coming through.

      No. Imagine a super thin wall mini ice cube tray in a roll. That's what Ditra is. It's an Uncoupling membrane. It does just that. You spread Thinset/Allset on the floor in a wet soupy consistency that integrates into the mesh fiber on the bottom of the ditra. Then you mortar that ditra ice cube tray full then scratch lines with your Thinset/Allset mixed normal and lay tile all while wet. It separates the movement in the subfloor from your Ditra and thinset.

    The issue i see here is, yes this membrane may be flexible, but tile and thinset/mortar are not meant to flex. So what's the point of a flexible subfloor if your main floor isn't flexible? Also, at the end of the day you're tiling over plastic... I could pull off a tile from this membrane even after 30 days of cure. I don't know how we've come to the point of thinking tiling over a plastic sheet is a job well done.

      You misunderstood how the system works. There is no 'flexing'. If the floor flexes it can't handle tile period. No, you could not just pull a tile off ditra. It's not easy to pull up the tile or the ditra once put down properly and cured.

  • @dona9380

    Doesn't the mortar you apply under and above membrane get hard after installation, making the uncoupling membrane absolite? Seems like the only benefits of this membrane is the ease of carrying, and cutting into the area your installing tile.. I did hear him say something about indentations in the membrane but we go back to both sides of the membrane being completely solid after applying mortar? Thoughts?

    Hey Sal, very good information, thanks. QUESTION- - - - I see the these non-coupling membranes suggest only 2" or larger tile. I need to put down a marble mosaic that consists of 1-1/6" hexagon pcs of marble, comes in 12x12 sheets. Is using a smaller mosaic for the floor ok? If not, what do you suggest?
    Here is my floor prep: I have a 5/8" subfloor, and I'm adding 15/32" BC underlayment on top. I'm also beefing up floor joists that are 16 OC and "sistering" some 2x6 SYP onto my 2x10 (9-1/4) Floor joists to help with deflection. This will also help reduce my OC dimension and help with a slight leveling problem. (I'm Using 2x6 so they pass over the top of my wiring and plumbing running through the joists). I'll probably add some cross blocking too, especially at all new subfloor joints. Using deck screws for subfloor. I'll thinset the membrane to BC underlayment like you suggest, then tile the mosaic as usual.

    • @SalDiBlasi
      @SalDiBlasi  4 роки тому

      Call your rep, in a residential tile job they will usually give you the OK for the smaller tile, and will give you a warranty, but you need to call and follow their instructions, which will usually mean prefilling the ditra before setting the mosaic tile.

    I have a subfloor that is needs some kind of board (like cement backer or plywood) because it’s a series of 2x8 planks. There are half inch gaps between these planks and some height differences. Can i put down a 1/4” cement board and then apply Ditra on top of it? This would level my floorboard and then provide the decoupling. I guess I’m really trying to avoid floating.

    Again, thank you very much for sharing your experience and knowledge.
    I plan to replace kitchen tiles(14 years old)- some of them cracked, sitting on metallic/cement "bed".
    And I planned to use cement boards to add rigidity to the kitchen floor, especially that tiles cracking shows some movement.
    After watching this video, I m not so sure what would be the best approach.
    May be to install Ditra instead of cement boards?
    What would you recommend and why?
    By the way your recommendations about Kerabound T worked perfectly- it was perfect to put tiles on ceiling, no problems at all.
    Thank you

Just because something works, doesn't mean it can't be improved upon. There were plenty of problems with Water in water out shower systems, cement board on a floor is not an ideal product to work with, it is heavy, dusty and has dangerous silicates, it is difficult to work with, and the list goes on. So just because something works it doesn't mean it is the best possible solution to a problem.
