Waterproong Accessories Installation Guide

SUBFLOOR PREP

The substrate must be clean, even, and load bearing. The thin-set mortar used for bonding the Waterproof Membrane must be appropriate for the

substrate and it must penetrate and engage the Membrane’s eece. We recommend using a modied thin-set mortar to install the Membrane to

a vertical substrate. Cut the Membrane to size prior to application.

STEP 1

Apply thin-set mortar to the substrate using a 1/4” x 3/16” (6 x 5 mm) V-notch trowel.

Press the Membrane fully into the bond coat. Work the Membrane into the mortar by

applying pressure to the Membrane with the at side of the trowel (held at an angle)

in smooth, diagonal sweeps. All air bubbles must be removed.

STEP 2

Seams can be constructed by overlapping the edges of the Membrane 2” (5 cm) using unmodied or modied thin-set

mortar, or by abutting the edges and covering the joint with Seam Tape using an unmodied or modied thin-set mortar.

STEP 3

For inside and outside corners, adhere pre-formed Waterproof Inside and Outside Corners. For oor/wall connections, use Seam Tape. Install

Pipe Collars at shower head, body sprays, etc. and Mixing Valve Collar at the mixing valve. As an alternative to the Pipe Collars and Mixing Valve

Collars, other suitable sealants can be used to seal pipe protrusions and protect moisture sensitive solid backing panels at the mixing valve.

STEP 4

Once the entire membrane - with seams, corners, and connections - has been completely bonded, and therefore

waterproofed, the tile/stone may be applied. Note: Water testing of the assembly

Prior to setting tile, wait 24 hours to allow for nal set of the mortar before testing to ensure waterproof perfor-

mance of the assembly at seams and connections.

Note: For tile installations using the thin-bed method, apply unmodied or modied thin-set mortar directly to the

exposed Membrane surface and install the tiles, ensuring full coverage. For acid-resistant coverings, use an epoxy

adhesive to set and grout the tile.
