Kerdi-Board Kit Simplifies Shopping and Installation for Tile Projects
Tiled shower walls are luxurious, hygienic, and easy to maintain. Whether the setting is a tub surround or a standalone shower, the walls must be waterproof before the tiles are installed. Schluter Systems’ new Schluter®–KERDI-BOARD KIT includes everything needed to build waterproof walls for a standard tub surround or an acrylic shower base, all in a package that can easily fit into most vehicles.
The kit creates a completely waterproof environment and prevents damaging leaks and mold growth due to moisture penetration. The kit includes 8 pieces of ½”-thick Kerdi-Board waterproof building panels that can be screwed directly onto wall studs to build a waterproof tub surround or shower area. These building panels are the first step in getting the walls ready for tile installation. The panels are 48” x 38” so they are a very manageable size and can easily be cut with a utility knife to fit any wall space up to 101 sq. ft.
The Kerdi-Board panels are lightweight, don’t generate dust when cut and completely eliminate the need for gypsum or cement board on the shower walls. The panels are installed with screws and washers that are included in the kit. Once the panels are up only the seams between panels and the screw penetrations need to be waterproofed to complete the walls. The kit includes a 5” wide strip of Kerdi-Band waterproof membrane that can be cut and then installed using thin-set mortar to seal these areas. Tiles are then set directly onto the KERDI-BOARD with thin-set mortar. This system is not only waterproof but vapor tight so it won’t leak or promote mold growth.
The kit also includes two tubes of KERDI-FIX sealing and bonding compound to create a waterproof seal around the flange of the tub or shower base. This is a particularly vulnerable area for moisture penetration so obtaining a proper waterproof seal where the tiles meet these elements is critical. Other components in the kit are a 4-1/2” mixing valve seal, a ¾” pipe seal and a ½” pipe seal to ensure that no moisture can enter the wall cavity where the plumbing fixtures protrude into the shower area.
