Tremco Vulkem 350/351
A composite waterproofing system comprised of toughcuring liquid polyurethane that is used as a Pedestrian Coating System
Vulkem 350/351 is a composite waterproofing system comprised of tough- curing liquid polyurethane. It cures to form a rubber membrane surface that provides a lasting and easy-to-clean coating. Textured surfaces for pedestrian traffic will use an aggregate-laden top membrane to aid in wear and slip resistance. Vulkem 350/351 may be used to apply a seamless, monolithic waterproof membrane to concrete and primed metal surfaces.
Vulkem 350 Base Coat is a single-component urethane membrane that bonds firmly to clean, dry concrete and metal. It retains its integrity even if substrate movement causes hair-line cracks of up to 1/16″” (1.5 mm). If cut or damaged, Vulkem 350 will prevent water migration between itself and the substrate. Vulkem 350 is available in roller (R) and in self-leveling (SL) grade for vertical and horizontal application.
Vulkem 351 Top Coat is an aliphatic, single-component polyurethane, which when used in conjunction with the recommended aggregate, creates a tough, aesthetically appealing, skid resistant, wearing surface that forms a strong interlaminate bond to the Vulkem 350 basecoat.”
