GacoFlex S42

The high adhesion alternative to replacing your weathered roof.

GacoFlex S42 Series is a 100% silicone roof coating solution for renewing your weathered roof. This high adhesion coating can be installed over virtually any existing roof substrate* creating a durable, seamless membrane that helps protect the roof from permanent ponding water, ultraviolet light and severe weather.

GacoFlex S42 Series covers more surface area with less material than many other competitive silicones, exhibits outstanding peak hide coverage on granulated surfaces, and with its strong adhesion to multiple types of surfaces, it eliminates the need for an epoxy primer in many cases, allowing for faster installation.

Benefits

IMPROVED ADHESION. Eliminates the need for primer on most substrates*, compared to previous generation GacoFlex silicone coatings.

EXCELLENT COVERAGE. Covers more surface area with less material than GacoFlex S20 series of silicone coatings, and that of many other competitors (1.25 gal/sq vs 1.5 gal/sq).

OUTSTANDING PEAK HIDE. Requires less coating to cover peaks on an uneven surface.

100% SILICONE. A single component elastomeric coating ideal for renewing your weathered and leaking roof.

CAN WITHSTAND PERMANENT PONDING WATER. GacoFlex S42 silicone coatings can help prevent roof softening, bubbling or degrading under permanent ponding water.

EXTEND THE LIFE OF YOUR ROOF by recoating your weathered roof with GacoFlex S42 silicone coatings.

*Always perform an adhesion test to ensure compatibility.
