DITRA is specifically designed to allow the installation of ceramic and stone tile over any even and load-bearing substrate. The integration of DITRA’s uncoupling, waterproofing, load-distribution, and vapor management functions makes consistent results viable.
Is DITRA better than cement board?
Schulter Ditra or Cement Board (Hardibacker, Durock, Wonderboard, etc.) is typically used as a tile substrate because it is durable, water resistant, and does not expand, contract, or warp when exposed to moisture. Schluter Ditra is superior to cement board in all categories except price and durability.
What goes under DITRA membrane?
For example, to set DITRA over plywood or OSB, a modified thin-set mortar meeting the requirements of ANSI A118. 11 is used. To set DITRA over concrete or gypsum, Schluter-Systems recommends an unmodified thin-set mortar meeting the requirements of ANSI A118.
How long after laying DITRA can I tile?
How long do I have to wait before I can install tile on the Schluter®-DITRA membrane? Once DITRA has been installed on the substrate, tile can be installed right away. No need to wait for the mortar to cure.
Is DITRA mat waterproof?
Waterproofing – DITRA Matting creates a waterproofing assembly with the tile layer, as long as the joints, floor to wall transitions and connections to building fixtures are properly installed.
Can DITRA be used with porcelain tile?
Therefore, extended cure times would be required before grouting if using modified thin-set mortars between DITRA and ceramic tile, including porcelain tile. If extended cure times were not observed, the results could be unpredictable.
Can I tile directly onto plywood?
Tile can be laid on plywood. But do not install tile directly on the plywood subfloor itself. Use an intervening layer of a sheet of thinner plywood.
What is CBU Backerboard?
Cement backer board, also called a cementitious backer unit or CBU, is commonly used to form a base for ceramic tile. Because cement backer board is porous, thin-set, grout, and mortar adhere well to it. Backer boards can be nailed or screwed into studs or cinderblock, brick mortar, or concrete.
How thick should subfloor be for DITRA?
DITRA allows for ceramic tile application over single-layer plywood or OSB subfloors on joists spaced up to 19.2″ (488 mm) o.c. DITRA-XL is 5/16″ (7 mm) thick, which permits even transitions between tile and 3/4″-thick hardwood flooring.
Can you walk on DITRA after install?
Pro-Tip: DITRA can be walked on immediately after; there’s no need to wait for the mortar to cure.
Can you put DITRA on subfloor?
DITRA is way easier to install than cement board. First, it’s light. Second, it stops tile and grout from cracking. Third, it can waterproof the wood subfloor.
Should plywood be primed before tiling?
If tiling on fibre-reinforced cement sheets, or plywood/chipboard, then we would always recommend priming the reverse side and edges with BAL Bond SBR. This helps protect the plywood from moisture penetration which could cause the board to swell.
