UNIFLEX® Silicone22™ Rubberized Silicone White Roof Coating is a low-solids silicone rubber roof ideal for ponding water. RECOMMENDED USES: Metal, single ply, smooth BUR, APP, SBS, modified bitumen, polyurethane foam, cured concrete, existing asphaltic and elastomeric roof coatings and other approved surfaces. NOT for use on roof shingles. EPDM rubber roofs must be primed with bonding primer designed for EPDM roofs. Other roof substrates including metal, asphalt or concrete may require primer before application. An adhesion peel test should be performed to determine if a primer is needed. Asphalt-bleed blocking primer is recommended over asphalt substrates to limit staining and discoloration.
