Installation Requirements

Basic Installation

SUBSTRATE BOND COATING

Install COMPOSEAL WHITE GOLD membrane using any Latex-Portland Cement (modified thin-set) Mortar complying with ANSIA118.4-2010 according to manufacturers directions.

For faster installation and with any substrate suspicious of water migration a rapid setting Latex-Portland Cement Mortar complying with ANSI A118.4-2010 should be used. Rapid setting mortar installation has the advantage of allowing same-day setting of tile above the membrane. Verify bonding mortar as to manufacturer’s compatibility with membrane.

TILE BED SETTINGS

Tile is bonded directly to COMPOSEAL WHITE GOLD using the thin-set method in accordance with ANSI A108.5-2010 and using ANSI A118.4-2010 Latex-Portland Cement Mortar.  A thick-setting wire reinforced mud bed in accordance with ANSI A108.1-2010 may also be used. Accessory Installation Material

Accessory Installation Material

Acoustical Sealant is required at the perimeter of the floor, and at any penetration of the floor inside the perimeters. There should be a 3/8” wide joint at these locations, that continues through tile work. Neither tile nor setting mortar should touch the walls or protruding pipes, etc. However, in waterproofing installations, the COMPOSEAL WHITE GOLD membrane should be extended 6” min. up the wall.

SEAM WELDING

COMPOSEAL WHITE GOLD is welded with the Composeal Flexible PVC Solvent Cement applied generously through the fleece of both pieces to be welded. Once cement has become tacky the layers are ready to be placed together with a 2” overlap. Verify complete adhesion through membrane layers.

CORNERS

Pre-formed COMPOSEAL GOLD inside and outside corners are available for waterproofing jobs.

FLASHINGS & SEALANTS

COMPOSEAL WHITE GOLD is bonded to metal flashings, drains, protrusions etc. with Compotite Elastiseal or a 100% mold/mildew resistant silicone.
