Installing tiles using the thin-set method requires substrates to be clean and even. Masonry walls and existing/mixed substrates are often unsuitable for direct application of tile because they can be uneven or difficult to bond to.
Schluter-KERDI-BOARD is ideal for installation on:
Depending on the condition of the existing wall areas, Schluter-KERDI-BOARD can be either fully embedded in thin-set mortar or spot-bonded. Spot-bonding the panels with thin-set mortar allows for adjustment to achieve plumb wall surfaces.
Schluter-KERDI-BOARD can be installed vertically as well as horizontally. Where wall surfaces will not accept a bond to thin-set mortar, Schluter-KERDI-BOARD can be further attached with the help of the special anchors included in our hardware assortment.
Tiles can be installed over KERDI-BOARD with thin-set mortar immediately; no additional prep is required.
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.
If the substrate is sufficiently even to allow for fully embedding the panels in thin-set mortar, panel thicknesses from 3/16" (5 mm) can be selected. If the panels are to be spot-bonded, thicknesses of 3/8" (9 mm) or more are required, depending on specific project requirements.
