Vulkem® 360NF/950NF/950NF

Vehicular Coating System - Elastomeric, Waterproof Indoor

Vulkem® 360NF/950NF/950NF is a modified polyurethane traffic deck coating system composed of a base coat (360NF), heavy duty intermediate coat (950NF) and a top coat (950NF). This unique waterproofing system is designed to have tenacious adhesion, extreme impact and abrasion resistance along with remarkable chemical stability. The elastomeric properties of the system’s components enable the complete assembly to give and work with the concrete slab, bridging the shrinkage cracks.

Basic Uses
  • Vulkem 360NF/950NF/950NF is a cold-applied traffic deck coating system designed for waterproofing concrete slabs and protecting occupied areas underneath from water damage.
  • Additionally, the system will protect the concrete from the damaging effects of water, deicing salts, chemicals, gasoline, oils and anti-freeze.

Product Details, Safety, and Installation
  • How long must Vulkem coating systems be allowed to cure prior to exposure to pedestrian/ vehicular traffic?

    Minimum recommended cure times are as follows: Vulkem 350 with 950NF or 951NF Pedestrian Deck Coating is 12 hours. Vulkem 350/351 Pedestrian Deck Coating and the Vulkem 350/950NF/951NF Vehicular Traffic System are 24 hours. The Vulkem 350/346/346 Vehicular Traffic System is 72 hours. Please note that these are minimum recommended cure times and site specific conditions, weather and temperature all impact cure rate and interlaminary adhesion development. Contact your local sales representative for project specific recommendations.

  • I am in the process of applying one of Tremco's multi-coat Vulkem Traffic Coating Systems and it has rained. What do I need to do prior to proceeding?

    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 Primer 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 Primer 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’s Technical Services team.

  • What is the minimum application and curing temperature for Vulkem Traffic Coating Systems?

    Vulkem Traffic 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.

  • What general recommendations should be followed when applying Vulkem Traffic Coatings to plywood or metal substrates?

    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 Tremco’s TREMprime Non-Porous Primer.  For priming coverage rates and application techniques, please call Technical Service.

  • How long should concrete be allowed to cure prior to the application of Vulkem Traffic Coatings?

    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 Traffic Coatings. Contact Technical Services for preferred or approved gauges and evaluation methods.

  • Can I apply Vulkem Traffic Coatings over concrete that has curing agents, sealers or water repellants applied to the surface?

    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.

  • What is the service temperature range for traffic coatings?

    The service temperature range for traffic coatings is -40°F to 185°F (-40°C to 85°C).
