Vulkem® 350NF/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 350NF/351 may be used to apply a seamless, monolithic waterproof membrane to concrete and primed metal surfaces.
Vulkem 350NF/351 is ideal for plazas, recreation decks, balconies, mechanical rooms, stadiums, athletic surfaces, and similar applications requiring an elastomeric waterproofing system.

Vulkem Deck Coatings should be applied to dry, frost-free substrates having a temperature of 40°F (5°C) and rising. For specific project recommendations, please contact Technical Services or your local sales representative.
Concrete should be water-cured and in place a minimum of 14 days, and rubber mat tested, thermal imaged or otherwise evaluated for maximum allowable moisture prior to the application of Vulkem deck coatings. Contact Technical Services for preferred or approved gauges and evaluation methods.
Vulkem Coatings should not be applied to concrete that has had curing agents, sealers or water repellants applied. All concrete surfaces must be clean, sound and free of all contamination. Chemical and/or mechanical surface preparation may be required. Contact Tremco Technical Services or your local sales representative for project specific requirements.
Wood must be a minimum 5/8” (16mm) thickness exterior grade plywood laid with the "A" side up and securely fastened to meet local uplift and other building code requirements. A consistent 1/16" joint should be provided between adjacent panels. See Tremco details for appropriate detailing of joints prior to application of coating. Reference system specific product data sheets for priming requirements and other application guidelines. Metal substrates must be restored to a clean, bright finish free of oxidation, previously applied coatings and other residue or contaminants. Metal substrates should be primed with the Tremco TREMprime Nonporous Primer. For priming coverage rates and application techniques, please call Technical Service.
It is the intent of this web-based color guide to provide a basic representation of these colors. Colors viewed on a computer screen or printed will vary from one computer to another due to differences in monitor calibrations and printer configurations. They will never be an exact representation of actual colors. Prior to starting any project, an on-site color mockup is recommended using the same color, texture and application techniques proposed by the contractor.
