Composeal Grey Gold 50 mil PVC membrane controls sound transmission in high quality thin-set tile installations protects from substrate cracks & moisture mitigation. Made of 50% recycled material.
Substrate Bond Coat
Install COMPOSEAL GREY GOLD membrane using any Latex-Portland Cement (modified thin-set) Mortar complying with ANSI A118.4 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 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 Setting Bed
Tile is bonded directly to COMPOSEAL GREY GOLD using the thin-set method in accordance with ANSI A108.5 and using ANSI A118.4 Latex- Portland Cement Mortar. A thick-setting wire reinforced mud bed in accordance with ANSI A108.1 may also be used.
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 GREY GOLD membrane should be extended 6” min. up the wall.
Seam Welding:
COMPOSEAL GREY 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. Flashing and Sealants: COMPOSEAL GREY GOLD is bonded to metal flashings, drains, protrusions etc. with Compotite Elastiseal or a 100% mold/mildew resistant silicone.
