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 ### ⭐⭐⭐⭐⭐ Review *by M***O on 4 July 2022* ### ⭐⭐⭐⭐⭐ Review *by R***S on 8 June 2025* ### ⭐⭐⭐⭐⭐ Review *by A***R on 30 September 2017* ## Frequently Bought Together - Schluter Systems Kereck/FI 2 Kerdi Inside Waterproofing Corner - 4 Mil Thickness - Seamless Corners for KERDI, KERDI-Board, and DITRA Assemblies - 2-Pack - KERECK/FI2 - Schluter Kerdi-Kereck Preformed Waterproofing Outside Corner - Seamless for Shower System Integration, Leak and Water Damage Protection - 90-Degree, 2-Pack - KERECK/FA2 - Schluter Kerdi Band Waterproofing Strip - Ideal for Sealing Butt Joints and Floor/Wall Connections - 33' Length, 5" Width, 4 mil Thickness - KEBA100/125/10M --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/280942735-schluter-systems-kereck-fi-2-kerdi-inside-waterproofing-corner-4](https://www.desertcart.us/products/280942735-schluter-systems-kereck-fi-2-kerdi-inside-waterproofing-corner-4) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-08*
