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". ## Customer Reviews ### ⭐⭐⭐⭐⭐ Corner seal *by R***S on June 8, 2025* Good but expensive. ### ⭐⭐⭐⭐⭐ Fast Delivery *by A***N on August 14, 2021* Works like a charm ### ⭐⭐⭐⭐⭐ The Shluter corners were so easy to install and I am confident in the system ... *by M***Y on June 1, 2018* The Shluter corners were so easy to install and I am confident in the system keeping the walls from getting water damage.
