Vulkem 350NF 351 Outdoor Pedestrian system

Vulkem 171/350NF/351 is an attractive composite waterproofing system comprised of tough-curing liquid polyurethane. It cures to form a rubber membrane surface that provides a lasting eye-appealing and easy-to-clean coating. Textured surfaces for pedestrian traffic features use of an aggregate-laden top membrane to aid in wear and slip resistance. Vulkem 171/350NF/351 may be used to apply a seamless, monolithic waterproof membrane to concrete.

Vulkem 350NF is a one part, low odor, low VOC urethane membrane that bonds firmly to clean, dry concrete. It retains its integrity even if substrate movement causes hairline cracks of up to 1/16” (1.6mm). Vulkem 350NF is available in an R (roller) and an SL (self- leveling) grade for vertical or horizontal use.

Vulkem 351 is applied after the Vulkem 350NF base coat has cured. The finished top layer affords excellent abrasion resistance and outstanding elongation and recovery to expand and contract with substrates. Interlaminary adhesion to Vulkem 350NF is exceedingly strong.
