Products / WeatherBond X-Tenda Coat XTRA Silicone Roof Coating

A 100% silicone, solvent-free, one-component, moisture-curing roof coating at 93% solids by volume for smooth asphaltic BUR, smooth or granulated cap sheets, single-ply, well-adhered acrylic coatings, metal and concrete, which the bulletin says can be applied above 50 mils in one coat. A typical rate of 1.0 to 1.5 gallons per 100 square feet yields about 15 dry mils; it ships in 5 and 55 gallon containers. The bulletin lists ASTM E108/UL 790 Class A, an ASTM D7281 water leakage pass at 22 dry mils or more, FM approval, NSF rainwater- catchment listing, and an initial SRI of 110 (106 aged).
