GacoFlex S20

Solvent-Free 100% Silicone Coating

Whether your roof is large or small, flat or sloped, GacoFlex S20 Series Solvent-Free 100% Silicone Roof Coatings provide a proven, guaranteed solution for renewing your weathered and leaking roof. They can be applied to virtually any existing roof to create a durable, glossy, seamless membrane that seals and protects against permanent ponding water, ultraviolet light and severe weather.

GacoFlex S20 is certified to NSF P151, an independent testing protocol for rainwater catchment systems, and found not to impart contaminants that exceed the U.S. Environmental Protection Agency’s drinking water regulations or advisories.

Benefits

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

HIGH SOLIDS. GacoFlex solvent-free silicone coatings are made almost entirely of solids. 95% of what is in the can stays on the roof!

WORKABILITY. GacoFlex S20 Series can be applied to virtually any existing roof to create a seamless membrane in one coat on smooth surfaces. The coating can also be rained on within 2 hours.

FM APPROVED. S20 does not change the FM rating for fire, wind and hail. GacoFlex S20 Series is the only roofing coating in the industry with this certification.

DECADES OF PROVEN PERFORMANCE. All GacoFlex Silicone Roof Coatings carry a 50 Year Limited Material Warranty. In addition, a Labor & Material Warranty is available to Gaco Western Qualified Applicators when GacoFlex S20 Series coating is applied over E5320 2-Part Epoxy Primer/Filler and according to Gaco Western specifications.

ADHERES TO A VARIETY OF SUBSTRATES. GacoFlex S20 Series are ideal for use as a maintenance coating system over pre-existing elastomeric roof coatings, metal roofs, built-up roofing, mineral cap sheet and weathered single ply membranes (EPDM, Hypalon and TPO/CPA), sprayed polyurethane foam roofing systems and many other coatings.

RAINWATER CATCHMENT SYSTEM APPROVED. Certified to NSF P151.

WITHSTANDS PERMANENT PONDING WATER. This innovative coating is an excellent choice for flat roofs. Extremely durable, S20 will not soften, bubble or degrade under permanent ponding water.

PREVENTS COSTLY TEAR OFFS. By recoating your weathered roof with S20 silicone coatings, you not only extend the life of your roof, you avoid the need for a time-consuming and costly tear off.
