Silicone Roof Waterproofing System
SL450 is a fluid-applied, white, tough, and flexible silicone roof waterproofing membrane, formulated with 100% solvent-free polymers. As part of our advanced silicone coatings line, SL450 creates a thick, rubber-like protective layer that expands and contracts with roofs, ensuring long-lasting durability. It effectively waterproofs flat roofs, pitched roofs, parapet walls, concrete roofs, metal roof decks, terraces, and more, providing a seamless membrane that remains watertight longer than conventional seamed roofs. Unlike traditional materials, SL450’s silicone coatings resist cracking, crumbling, or peeling, even under severe weather conditions and total joint movement.
