Gaco S20 Commercial Roof Silicone Coatings:

Silicone is the smart choice when compared against any acrylic Commercial Roof Coatings. A silicone restoration membrane delivers superior UV resistance, adhesion, and reflectivity.

UV Resistance:

Unlike acrylic roof coatings that chalk, discolor, crack and haze when exposed to ultra-violet rays, silicone restoration membranes provide an in-organic, high solids elastomeric roof coating that will not degrade, chalk or crack under even the most extreme UV attack.

Stays Strong in Ponding Water 

Traditional elastomeric/acrylic roof coatings are water-based and cure when water evaporates. When ponding water is present on roof surfaces for a period of 48 hours or more, acrylic roof coatings can begin to re-emulsify to their liquid state and lose adhesion. In contrast, silicone coatings cure and cross-link by reaction with moisture in the air. Silicone cannot re-emulsify due to exposure to standing water. Gaco S20 is a non-water based, high-solids silicone roof coating. As such, when ponding water is present, S20’s adhesion to the roof substrate is not affected.

Reflectivity Saves Energy –

Using white silicone roof coating on a roof saves building energy use by as much as 15% to 35%

Engineered To Last – 

GacoSil S-20 is a single-component, moisture-curing silicone rubber roof coating designed for use on sprayed-in-place polyurethane foam, metal, concrete, wood, built-up roofing and most single-ply roofs.

Flame Resistant – 

GacoSil S-20 has passed the ASTM E108 flame spread test and obtained the Underwriters Laboratories Class A fire rating – the highest level of fire protection available. Other ASTM testing provided ratings for tensile strength, tear resistance, hardness, water immersion, permeability, reflectance, emittance and flash point. This is Paramount in any Commercial Roof Coating Application.

Benefits of Silicone Roof Coatings

Besides the fact that weather is not as big a factor when installing a silicone based roofing system, there are many other benefits:

  • Cost reduction from lower labor costs.
  • Contractor friendly with the lowest VOC on the market.
  • Environmentally friendly, as it reduces the need for roof tear-off.
  • Solvent and petroleum free
  • Can Contribute uo to 7 LEED points; Rated by Cool Roof Rating COuncil (CRRC)
  • No Ponding Water Issues
  • Less Dirt Pickup than conventional silicones
  • Durable, color stable, chalk and chemical resistant
