GacoFlex S2100

Cleanable Solvent-Free Silicone Coating

GacoFlex S2100 is the only cleanable solvent-free 100% silicone coating in the industry to resist dirt pick-up even after years of exposure, thereby maintaining significantly higher whiteness and solar reflectivity than other silicones. S2100 offers the same benefits as other GacoFlex silicones, now with the added advantage of reduced dirt accumulation and improved clean-ability.

S2100 does not contain crystalline silica and contains 37% recycled content – the highest in the industry. In addition, the use of S2100 on a job may contribute to LEED points.

Gaco offers a 5-Year Energy Star Warranty on our GacoFlex S2100 Cleanable Silicone Coating. When properly applied, we guarantee S2100 will maintain an aged Energy Star rating for a minimum of 5 years – even over asphalt roofs.

IMPROVED CLEAN-ABILITY. S2100 showed 40% less dirt accumulation, 2x the whiteness retention and maintained a higher solar reflectance and thermal emittance than competitive silicone coatings.

WHITENESS RETENTION. GacoFlex S2100 develops water sheeting action that allows roofs to dry more quickly, thus reducing dust and dirt interactions with the coating to keep the roof looking whiter, for longer.

5-YEAR BRIGHTNESS WARRANTY. Our 5-Year Brightness Warranty guarantees that when properly applied, S2100 will maintain its brightness and color uniformity for a period of 5 years – even over asphalt roofs.

LEED POINTS CONTRIBUTION. GacoFlex S2100 contains 37% recycled content and does not contain crystalline silica. Municipalities and companies encourage the use of products that reduce the amount of impact on our environment and S2100 has the highest recycled content in the industry. In addition, the use of S2100 on a job may contribute to LEED points.

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!

EXCELLENT FILM BUILD. Improved rheology provides better film build on high spots and over granulated or uneven surfaces.

ADHERES TO A VARIETY OF SUBSTRATES. GacoFlex S2100 is 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.

WITHSTANDS PERMANENT PONDING WATER. This innovative coating is an excellent choice for flat roofs. Extremely durable, GacoFlex S2100 will not soften, bubble or degrade under permanent ponding water.
