Installation Guide

Prefabricated substrates are made of expanded polystyrene foam, for use in conjunction
with the KERDI waterproofing membrane. KERDI-BOARD prefabricated substrates are
made of KERDI-BOARD, and are waterproof and ready for tile. A pre-cut section of
KERDI matching the dimensions of the tray is included with the KERDI-SHOWER-
ST for convenience. Prefabricated substrates provide an alternative to shower bases
constructed of mortar and other shower elements constructed of framing and solid
backing. KERDI-BOARD-SB prefabricated triangular benches include KERDI-KERECK
and KERDI-KERS-B preformed waterproofing corners. KERDI-BOARD-SB rectangular
benches include KERDI-KERECK preformed waterproofing corners.
