Tiled showers and bathtub surrounds require proper moisture management to ensure successful long-term performance. While cement backerboards are moisture-resistant, they are not waterproof. Thus, additional measures must be taken to protect wall cavities from water and vapor penetration.
In addition to being lightweight and easy to cut with a utility knife, Schluter-KERDI-BOARD is inherently waterproof and vapor-retardant. When used in conjunction with the Schluter-Shower System, KERDI-BOARD provides an integrated tile backing and moisture management system for tiled showers and bathtub surrounds.
Schluter-KERDI-BOARD is suitable for use in bonded waterproofing assemblies. For this purpose, the corners and joints must be sealed with Schluter-KERDI-BAND, using unmodified thin-set mortar. Fastener penetrations can be sealed with KERDI-BAND using unmodified thin-set mortar. Other protrusions through the KERDI-BOARD (e.g., showerhead, tub spout, etc.) must be treated with Schluter-KERDI-SEAL-PS seals or Schluter-KERDI-FIX.
Select the panel thickness depending on the installation methods and expected stresses of the project.
