Which thinset to use with Ditra?
To set DITRA over concrete or gypsum, Schluter-Systems recommends an unmodified thin-set mortar meeting the requirements of ANSI A118.
What happens if you use modified thinset on Ditra?
Since DITRA is impervious, it does not deprive the mortar of its moisture. This allows the cement to properly hydrate, resulting in a strong, dense bond coat. In general, we don’t recommend the use of modified thin-set mortar to set tile over the membranes because these mortars must air dry to cure properly.
Can I use premixed thinset with Ditra?
No. Schluter-Systems does not recommend the use of premixed thin-set mortars (mastics/adhesives) in any DITRA installation.
Does Thinset stick to Ditra?
While the membrane’s fleece IS bonded to the substrate, thinset does NOT stick to Ditra, and there are voids between the pillars that hold the tile up which means that if a lateral stress is applied, the whole tile and thinset layer can move totally independently of the subfloor or slab only restricted by the …
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.
What is the difference between modified and unmodified thinset?
Unmodified thinset has been around forever. Unlike unmodified mortar, which consists only of a blend of Portland cement, sand, and water retention agents, modified thinset includes additional retention products, such as latex polymers, which can increase its performance and strength.
Can you use tile adhesive on Ditra?
Gypsum based screeds Schlüter®-DITRA 25 can be applied using thin-bed tile adhesives that are suitable for the substrate. Schlüter®-DITRA 25 protects the screed against moisture penetration from the surface.
Is Versabond a modified thinset?
High bond strength, all-purpose, polymer-modified mortar adheres to most surfaces. For interior and exterior floors and walls.
