SILICONE HIGH BUILD COATING™
Silicone High Build Coating™ – 100% Seamless Protection
Reference # 18
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.
