Ditra Membrane Over Concrete

Please consult the schluter ditra installation handbook before beginning your tile project to confirm the proper materials selection.

Ditra membrane over concrete.

Uncoupling membranes are primarily designed for use over concrete slabs and subfloors especially ones with defects such as depressions or high moisture levels. Schluter ditra is specifically designed to allow the installation of ceramic and stone tile over any even and load bearing substrate. For example to set ditra over plywood or osb a modified thin set mortar meeting the requirements of ansi a118 11 is used. In addition they provide a stable substrate for tile installation on oily asphalt or extremely smooth surfaces for which adhesion is a problem.

The integration of ditra s uncoupling waterproofing load distribution and vapor management functions makes consistent results viable. The best part is that it solved my issue of heat loss through the cold concrete floor. 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. To set ditra over concrete or gypsum schluter systems recommends an unmodified thin set mortar meeting the requirements of ansi a118 1.

The schluter ditra heat duo membrane is 5 16 8 mm thick compared to ditra heat at 1 4 5 5 mm thick and has 4 benefits. Legend essential significant helpful uncoupling. 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. If it s newer and has cracks i wouldn t use ditra.

Ditra over concrete floors. The ditra heat duo has fleece liner that results in a 70 faster floor warming response time. Schluter ditra and redgard uncoupling mat are two popular brands of tiling membranes that lessen the chance of concrete events becoming tile events. The type of thin set mortar used to install ditra depends on the substrate material.

Depends on the condition of the slab and if it has any issues.
