Schluter ditra and ditra xl are specifically designed for ceramic and stone tile installations ditra and ditra xl provide uncoupling to prevent cracked tile and grout.
Ditra floor tile.
Ditra it goes down on top of wood or concrete subfloors.
And that isn t just the common bs everyone accuses failures on.
Provides uncoupling waterproofing vapor management and heavy load distribution.
I laid ditra into a layer of thin set then a layer of thin set on top of the ditra and back buttered my tiles as i laid them.
Ditra in my opinion is the best membrane for most floor tile installations.
Been installed a couple years now with no problem.
I used ditra for 12 quot.
Made of polyethylene ditra and ditra xl serve as a waterproofing layer that protects moisture sensitive substrates such as plywood osb.
So far so good.
Ditra is 1 8 in thick and is designed for ceramic and stone tile.
Ditra membrane is available in two thicknesses 1 8 and 5 16.
For my floor i had 3 4 1x10 on a diagnal and 1 2 exterior grade plywood screwed down every 4 square inches into the 1x10 s beneath it only.
Ditra matting and tile help the unmodified thin set retain more of its moisture as it cures and this creates a stronger bond than modified thin set can achieve.
For commercial and residential applications.
The only time i ve seen it fail is due to incorrect installation.
Your tile then goes on the ditra.
A word about ditra thickness.
Thus ditra effectively manages moisture beneath the tile covering.
Install ditra on a wood subfloor stop cracked tiles.
The distinguishing feature of ditra is the existence of free space created by the configured channels on the underside of the matting.
The free space provides an escape route for excess moisture and vapor that could otherwise cause damage to the tile layer above.
There was an alternative product mentioned in the forum thread called protegga which looks to be a slightly less expensive copy of the ditra you can read john bridge s comments about ditra knockoffs on his tile forum.
I ripped these 4 tiles up without much problem like ripping up glued down carpet it separated from both the floor and the ditra but excellent adhesion of the mortar to the tile.
Ceramic tiles that went down on 3 4 t g plywood underlayment.
1x10 s i screwed down.
Install over a wide range of substrates including plywood osb concrete gypsum heated floors etc.
Tile floors are beautiful durable and a fairly diy friendly option but for tile s good looks to really last it s vital to start with what you can t see the ideal underlayment.
But if it prevents your floor from failing after a few years then it s probably worth it.
