Do you need underlayment with DITRA?
In order to protect the integrity of the tile assembly, an underlayment that performs multiple functions is required. Schluter®-DITRA is specifically designed to allow the installation of ceramic and stone tile over any even and load-bearing substrate.
Which is better cement board or DITRA?
Ditra is waterproof, while cement board lets water through but won’t be damaged by it. This may make Ditra a better choice if moisture from below is a concern, such as with some outdoor applications or installations over concrete.
Is DITRA necessary on plywood?
Ditra should be installed on plywood subfloors using modified thinset mortar, not unmodified. The difference between the two is that the unmodified is a mixture of Portland cement, sand and water retention agents. Modified thinset mortar adds latex polymers to increase its adhesion and strength.
Can you tile directly to subfloor?
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 the proper subfloor for tile?
Exterior-Grade Plywood Exterior plywood is an acceptable underlayment for tile and is preferred to interior-grade plywoods because the bonding adhesives used are waterproof. If water seeps through the tile installation to the underlayment, it will not cause the wood to swell, as happens with interior-grade plywood.
Can you tile directly to plywood subfloor?
Can I tile directly over plywood?
What do I put between plywood and tile?
Thinset is the wet base that you first trowel on the plywood to make the tile stick. Higher latex content is essential for bonding to plywood. A quality unmodified thinset should be used and mixed with a latex additive.
What is Ditra used for in grouting?
DITRA and DITRA-XL provide uncoupling to prevent cracked tile and grout. Made of polyethylene, DITRA and DITRA-XL serve as a waterproofing layer that protects moisture-sensitive substrates, such as plywood/OSB.
Why do I need to use Ditra underlayment?
In order to protect the integrity of the tile assembly, an underlayment that performs multiple functions is required. DITRA is specifically designed to allow the installation of ceramic and stone tile over any even and load-bearing substrate.
How do you install Ditra?
DITRA is installed in thin-bed tile adhesive that is suitable for the substrate, using a notched trowel (recommended size: 3 x 3 mm or 4 x 4 mm). The anchoring fleece on the underside of DITRA is fully embedded and the fabric bonds with the adhesive. The curing time of the adhesive must be observed.
What is the thickness of Ditra?
DITRA is 1/8″ (3 mm) thick, which minimizes tile assembly thickness and reduces transitions to lower surface coverings (e.g., carpet, engineered wood, and vinyl). DITRA allows for ceramic tile application over single-layer plywood or OSB subfloors on joists spaced up to 19.2″ (488 mm) o.c. Uncoupling.
