Tile Shower - Installation Instructions using Prefabricated Tray
Schluter Materials Required for this Installation:
KERDI-DRAIN, KERDI waterproofing membrane, KERDI-BAND waterproofing strip, KERDI-SHOWER-ST prefabricated tray, and KERDI-SHOWER-SC prefabricated curb. (See picture 1)
Note: The type of bonding mortar used to apply KERDI must be suitable for the substrate. Generally, an unmodified thin-set mortar is used. Unmodified thin-set mortar must be used to construct all KERDI seams and to apply tile over the KERDI membrane.
Note: The KERDI-SHOWER-ST tray can be cut to size to fit various applications. Ideally, the tray should be cut by equal amounts on all four sides to ensure a consistent height of the first course of wall tile. The shower base can also be extended past the perimeter of the shower tray using dry pack mortar.
Note: Schluter-Systems recommends installing the KERDI-SHOWER-ST tray prior to setting KERDI-DRAIN whenever possible. This allows greater control over the final position of the drain and makes it easier to obtain full support under the bonding flange.
Note: When KERDI-DRAIN must be set by the plumber prior to the Schluter-KERDI-SHOWER-ST tray (or when there is no access to the plumbing from below), install the KERDI DRAIN to the appropriate height using the detachable center section (see figure 12-1) of the tray or the foam spacers (figure 12-2) included with the drain. Before installing the KERDI-SHOWER-ST tray, apply thin-set mortar to the substrate and to the top and bottom of the detached center section. Slide the cetner section into place below the drain to ensure solid and uniform support of the bonding flange.
