Overview
SMARTCOAT 450 High Solids Silicone Coating is a 100% silicone-based, solvent-free, single-part roof coating. Unmatched direct-bond adhesion, SMARTCOAT 450 is an ideal coating for low-sloped or flat roofing systems, vertical walls, masonry, granulated BUR/mod-Bit, granulated APP, concrete, metal, single-ply membranes, and spray polyurethane foam (SPF) systems. 450 creates a membrane that is vapor permeable, adaptive to temperature extremes, UV resistant, watertight, and weatherproof. This product exhibits outstanding ponding water resistance. #450 may be used to re-coat existing silicone roof coatings and existing acrylic roof coatings.
