Makers of COMPOSEAL GOLD anti-fracture Waterproof Membrane and COMPOSEAL Blue Vinyl Shower Pan, supplying the ceramic tile industry since 1938.

PP Product Presentation

COMPOSEAL WHITE GOLD is a 50 mil version of COMPOSEAL GOLD 40 mil, thickened to provide extra sound control for above grade thin-set ceramic tile or marble installations. COMPOSEAL WHITE GOLD is manufactured in 60" width packaged in 100 ft. and 40 ft. rolls.

Sound Control Capability

COMPOSEAL WHITE GOLD provides a sound rating of IIC 59 and STC 60 in above grade ceramic tile installations over 6" concrete slab floors above a California light weight suspended ceiling. Crack Suppression, Bonding Direct and Waterproof Capabilities are all equal or better than the superior performance record of COMPOSEAL GOLD 40 mil Crack Isolation Waterproof membrane.

UA Uses, Applications

COMPOSEAL WHITE GOLD is used as a concealed sound control and/or crack isolation and waterproof membrane under thin-set installations of ceramic tile and marble in new construction, renovation or repair in residential and commercial projects.

Negligible shrinkage at extreme temperatures combined with low water vapor permeability makes COMPOSEAL WHITE GOLD especially ideal for sound control on radiant heated flooring and steam cleaned floors.

Limitations

When COMPOSEAL WHITE GOLD is used for sound control and waterproofing, such as in showers, or on bathroom and kitchen floors, it cannot be bonded direct to any material adversely affected by water: plywood substrates must be covered with 1-1/4" wire reinforced mortar bed or cementitious backer units before bonding the WHITE GOLD.

COMPOSEAL WHITE GOLD cannot be used with asphalt or bituminous based products.

OP Overall Product In Place

The powerful sound control and crack protection provided by COMPOSEAL WHITE GOLD in above grade tile installations adds less than 1/8" to 1/4" to the overall thickness of the thin-set installation, and less than 1/3 lb. per sq. ft. to the overall weight.

CS Coatings, Surfaces

Substrate Bond Coat

Install COMPOSEAL GOLD sheets using a latex modified thin-set mortar complying with ANSI A118.4. The use of a rapid setting latex mortar to bond COMPOSEAL WHITE GOLD to the substrate allows same day setting of tile above the membrane.

Tile Setting Bed

Tile is bonded direct to COMPOSEAL WHITE GOLD using the thin-set method (ANSI A108.5) in accordance with TCA Handbook recommendations and using ANSI A118.4 latex Portland cement mortar.

MF Materials, Finishes

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 membrane may be extended 6" min. up the wall.

CC Code Acceptability, Certification

COMPOSEAL WHITE GOLD has been tested for Sound Transmission Loss as specified by ASTM E90-97 and ASTM E413-87 resulting in a Sound Transmission Class (STC) rating of 60. COMPOSEAL WHITE GOLD was also tested for Impact Sound Transmission as specified by ASTM E492-90 and ASTM E989-89, and given an Impact Isolation Class (IIC) rating of 59.
