Schluter-Systems requires the use of Schluter SET™ , ALL-SET™ , FAST-SET™, or an unmodified thin-set mortar meeting the requirements of ANSI A118. 1 to install ceramic. (including porcelain) and stone tile over DITRA and DITRA-XL.
Is Schluter Thinset worth it?
Expensive compared to similar products, however works well with Schluter/Kerdi products, and given the total cost of a remodel project the additional cost was worth the knowledge that it works and is guaranteed with the other products. Also, the ease of use is much better than standard unmodified thinset. Works great!
Can I use modified thinset with Schluter?
Formulated to be fully compatible with Schluter® products
The products are Schluter SET® unmodified thin-set mortar, Schluter ALL-SET® modified thin-set mortar, and Schluter FAST-SET® rapid-setting modified thin-set mortar. These products have been specifically formulated for Schluter® membranes and boards.
What happens if you use modified thinset on KERDI?
Modified thinset mortars aren’t recommended for use with Kerdi because they must dry out to gain strength, whereas the membrane inhibits drying, which can lead to unpredictable results. For example, if a shower is used before the mortar has cured properly, leaks and polymer leaching can occur.
Do you have to use unmodified thinset with Kerdi?
Schluter SET™, ALL-SET™, FAST-SET™ or an unmodified thin-set mortar must be used to construct all KERDI seams to ensure watertightperformance of the system.
What is difference between modified and unmodified thinset?
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.
How long does Schluter thinset take to dry?
Wait 24 hours after the membrane installation is complete to allow for the final set of the mortar and to ensure waterproof performance of the assembly at seams and connections before water testing.
Can you put Schluter over drywall?
Yes. Once you install KERDI over the drywall panels, they will be completely protected from the water and vapor in your tiled shower.
Can I use Schluter all set on cement board?
Schluter ALL-SET™ is a mixture of cement, sand, polymer and additives that sets and gains strength through cement hydration and polymer film formation when mixed with water. It is engineered for use with Schluter membranes and boards, including tile installation.

How long should Kerdi dry before tiling?
Wait 24 hours after the membrane (i.e., Schluter®-KERDI-BAND and Schluter®-KERDI) installation is complete to allow for the final set of the mortar and to ensure waterproof performance of the assembly at seams and connections before water testing.
How do you mix Schluter thinset?
For installing Schluter membranes, use 7.5 – 8.5 qts (7.1 – 8.0 L) of water to 50 lbs (22.7 kg) of mortar. For installation of tile, use 5.5 – 6.5 qts (5.2 – 6.2 L) of water to 50 lbs (22.7 kg) of mortar. 2. Mix at a slow speed (
Is Ditra set modified or unmodified?
Bostik Ditra-set
