Tremco Vulkem® 950NF & 951NF: Durable Protection for Traffic Decks

When it comes to protecting parking decks, ramps, and other concrete surfaces from heavy wear and harsh conditions, the Tremco Vulkem® Traffic Deck Coating System stands out as one of the most trusted solutions. Two of its most important components—Vulkem 950NF Wear Coat and Vulkem 951NF Top Coat—provide the strength, durability, and chemical resistance needed for long-lasting performance.

In this blog, we’ll break down what these products do, how they work together, and why they’re an excellent choice for commercial and industrial projects.

What is Vulkem 950NF?

The Vulkem 950NF Wear Coat is a two-part, aromatic polyurethane coating that delivers a tough, chemical-resistant wearing surface.

• Purpose: Serves as the intermediate wear layer in the traffic deck system.
• Application: Applied over the Vulkem 350 base coat at approximately 15 wet mils thickness, either rolled or squeegeed onto the surface
• Performance Features:
  • Provides abrasion resistance against heavy vehicular and pedestrian traffic.
  • Protects against chemicals, gasoline, oils, and de-icing salts.
  • Accepts broadcast aggregate (silica sand) to improve slip resistance and durability.

Usage Options: Can be applied in medium-duty or heavy-duty systems, with additional coats recommended for ramps, driving lanes, and other high-stress areas.

In short, Vulkem 950NF is the workhorse of the system, giving decks the resilience they need under real-world conditions.

What is Vulkem 951NF?

The Vulkem 951NF Top Coat is a two-part, aliphatic polyurethane coating applied after the 950NF layer has cured

• Purpose: Serves as the final protective layer of the system.
• Application: Applied at about 15 wet mils thickness using a roller.
• Performance Features:
  • Provides UV resistance, ensuring color stability and long-term durability even in sun-exposed areas.
  • Adds another level of abrasion resistance to withstand constant traffic.
  • Seals the system for enhanced chemical and weather resistance.
  • Available in multiple standard and special colors to suit design requirements

This top coat ensures the system not only performs under tough conditions but also maintains a clean, professional finish.

How Vulkem 950NF and 951NF Work Together

Think of Vulkem 950NF as the shield that takes the brunt of impact and abrasion, while Vulkem 951NF acts as the finishing armor that protects against UV, chemicals, and weathering.

Together, they:

• Create a seamless, waterproof, and slip-resistant surface.
• Extend the service life of concrete decks by protecting against cracking, spalling, and moisture intrusion.
• Support faster project turnaround, as the system can be open to vehicular traffic in as little as 24 hours after cure.

Key Benefits at a Glance

• Durability: Withstands heavy vehicle traffic and harsh chemicals.
• Safety: Aggregate loading in the 950NF layer provides slip resistance.
• UV & Weather Resistance: 951NF maintains performance and appearance under sunlight and environmental exposure.
• Fast Cure: The system cures quickly, minimizing downtime.
• Versatility: Suitable for parking garages, stadiums, loading docks, and more.

For contractors, facility managers, and property owners seeking a reliable traffic deck solution, Tremco Vulkem 950NF and 951NF deliver proven protection. By combining abrasion resistance, chemical stability, and UV durability, these coatings work hand-in-hand to safeguard concrete surfaces for years of dependable service.
