Reference # 18

 

5-gallon pail of Silicone High Build Coating used for commercial flat roofs

DESCRIPTION

Silicone High Build Coating is a premium-grade, high-solids roof coating engineered for extreme durability, waterproofing, and energy efficiency. This 100% silicone formula is solvent-free and moisture-cured, forming a seamless, flexible membrane that resists ponding water and harsh weather conditions. Its low viscosity makes application fast and clean, while its brilliant white finish reflects solar heat to lower rooftop temperatures and reduce energy costs. Approved for a wide range of roofing systems, this coating is the go-to solution for contractors seeking long-term protection and reduced maintenance needs.

  • Creates a seamless waterproof barrier that resists ponding water

  • Bright white, UV-reflective surface reduces energy loads

  • Bonds to metal, TPO, EPDM, PVC, spray foam & more — even unprimed

  • Flexible and crack-resistant across temperature extremes

  • Solvent-free and compliant with environmental standards

Cure Time: Tack-free in 2–4 hours depending on conditions.
Note: Not intended for use on asphalt shingle roofs.
Quantity and Color: Sold in 5-gallon pails. Cures white.
