Vulkem® 360NF/951NF 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 360NF/951NF may be used to apply a seamless, monolithic waterproof membrane to concrete, well-anchored AC plywood, and primed metal surfaces.
Vulkem 360NF/951NF is ideal for plazas, recreation decks, balconies, mechanical rooms, stadiums, athletic surfaces, and similar applications requiring an elastomeric waterproofing system.

Prior to proceeding, existing moisture should be removed and the surface should be wiped with a compliant, non-alcohol based solvent or other approved cleaner. Contact Technical Services for recommendations. Allow the solvent to flash dry. Prime using either Vulkem 191, Vulkem 191 Low VOC, or TREMprime Multi-Surface Urethane Primer. Primer selection is driven by local compliance and regulations and secondarily by contractor preference. Apply primer at recommended coverage rates found on the primer selection guide on the website. Dry times will vary by primer and will also be affected by temperature and humidity conditions. Vulkem 191 and Vulkem 191 Low VOC primers should dry to a "tack" and Tremco Multi-Surface Urethane Primer should be allowed to fully dry prior to proceeding with application of the subsequent Vulkem coating. Please consult Tremco Technical Service.
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.
