Ditra Mat On Concrete Slab

Ditra is good for new concrete.

Ditra mat on concrete slab. The combination of these four essential functions allows for the successful installation of tile over a wide range of substrates including plywood osb concrete gypsum heated floors etc. Un modified under and over the ditra. Ditra is essentially a molded plastic sheet with fleece backing. We recommend using schluter ditra heat duo uncoupling membrane.

The schluter ditra uncoupling membrane is specifically designed to allow the installation of ceramic and stone tile over any even and load bearing substrate. Ditra heat tb has additional insulation for going over concrete floors. Again i think this is a bad idea. 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.

This will reduce heat loss to the concrete substrate and improve the floor warming response time. Don t install tile the same day over the ditra heat mat schluter says this is ok. Its primary function is to help neutralize stresses in movement between the substrate in my case the subfloor but it can also work with osb or plywood and the tile.
