## Questions & Answers

**Q: Can this be installed/adhered with liquid applied membrane instead of thinset mortar? Thnks**
A: No, not at all. Do not use liquid membrane at all. If you are looking for a product besides Schluter's thinset you can use Mapei uncoupling membrane thinset. Alternatively, you can use any thinset that is A118.1; that number is a standard that companies must meet as the minimum strength requirement for adhesion for things like shear strength between bonded component(s) and substrate.

**Q: Will this flex to accommodate a slightly larger angle? My bench has a 93 degree slope for drainage.**
A: I don't thing the 3 degrees over 90 would make a difference.

**Q: Are there 2 corner pieces in this or only one?**
A: The package I have says it contains 2 corner pieces.

**Q: Why does the product description say these are pink?  the kerdi fabric i have is orange.  i don't want to order something that is not kerdi.**
A: looks like someone inserted the color "pink" because on the screen it looks "pink". So I assure you that it is Schluter "orange".
