Our indoor waterproofing systems, despite being eco-friendly products, are a highly efficient way to protect your shower from water leaks, floor and wall damage, moisture damage such as mold, and even flooding. 

Selecting the Right Mortar:

Selecting the appropriate thin-set mortar is crucial for the successful installation of the Schluter®-KERDI waterproofing membrane, as it ensures proper adhesion and performance. The choice of mortar depends on the type of substrate:
Gypsum Board, Cement Backerboard, or Similar Substrates: Use Schluter SET®, ALL-SET®, or FAST-SET® mortars, which are specifically designed to bond KERDI to these surfaces. These mortars effectively penetrate and engage the membrane's fleece, ensuring a strong bond.
Particularly Dry and Porous Substrates: When installing KERDI over especially dry or porous surfaces, it's recommended to dampen the substrate before applying the mortar. This practice helps prevent premature drying or skinning of the thin-set mortar, ensuring a strong bond.
For constructing all KERDI seams, Schluter-Systems requires the use of Schluter SET®, ALL-SET®, or FAST-SET® mortars to ensure the watertight performance of the system.
By selecting the correct thin-set mortar based on your substrate, you ensure a durable and long-lasting tile installation that maximizes the waterproofing properties of the KERDI membrane.

Comprehensive Shower Installation Accessories for Seamless Waterproofing:

Enhance your shower installation with a wide range of additional products designed for optimal waterproofing and functionality. Choose from waterproofing membranes, shower niches, benches, and shampoo shelves for added convenience and style. Complement your setup with curbs, shower trays, and advanced drain waterproofing systems, including ABS or PVC flanges, durable metal grates (covers), and strainers. Complete the waterproofing process with essential accessories such as sealing strips (bands), Kerdi-Fix sealant, inside and outside corners, and pipe and valve seals. These components work together seamlessly to create a fully waterproof, durable, and visually appealing shower system, ensuring long-lasting performance in both residential and commercial settings.
