Tremco Vulkem 951NF Top Coat

Tremco Vulkem® 951NF Top Coat

Aliphatic, Two-Component Polyurethane Traffic Deck Top Coat | Brand: Tremco

Tremco Vulkem 951NF is an aliphatic, two-component polyurethane top coat for vehicular and pedestrian traffic deck systems. Applied over compatible Vulkem base coats as part of an approved Tremco system, it is formulated for UV stability and wear resistance on parkades, podium decks, and exposed pedestrian areas. Confirm suitability, system compatibility, coverage, and cure requirements against the current Tremco TDS, SDS, and project specification before use.

Product Description

Vulkem 951NF is an aliphatic polyurethane formulated for UV stability and colour retention under prolonged sun exposure. As the final layer in a Tremco traffic deck system, it is designed to provide a wearing surface that protects the underlying waterproofing membrane from abrasion, chemicals, and weathering; confirm performance properties against the current TDS and project specification. Its two-component formulation requires accurate mixing at the specified ratio; confirm pot life, application temperature, and cure requirements against the TDS before use.

The NF designation indicates a non-flammable, low-VOC formula; confirm ventilation requirements against the SDS. Available in multiple colours to meet project aesthetic and safety-marking requirements; confirm colour availability with Canopus Supply before specifying.

Key Characteristics

• UV-stable, aliphatic chemistry — formulated to resist colour fade and chalking on exposed, sunlit deck surfaces; confirm UV performance against the TDS.
• Two-component system — requires accurate mixing at the specified ratio; confirm mixing requirements and pot life against the TDS.
• Non-flammable, low VOC — formulated for use in enclosed parkades and occupied-building work areas with appropriate ventilation; confirm ventilation requirements against the SDS.
• Abrasion and chemical resistance properties — formulated to resist vehicular traffic, tire scuff, de-icing salts, and fuel spills; confirm chemical compatibility and traffic suitability against the TDS and project specification.
• Seamless wearing surface — liquid-applied to form a continuous top coat over the waterproofing system; final performance depends on substrate condition, system design, and application method.
• Multiple colours available — confirm current colour availability and lead times with Canopus Supply before specifying.
• System-compatible — designed for use over Vulkem 350NF, 360NF, and other approved Tremco base coats; confirm system compatibility against the current Tremco specification.

Typical Applications

• Parkade and parking structure traffic deck top coat
• Podium and plaza deck wearing course
• Exposed pedestrian walkways and ramps
• Vehicular and pedestrian traffic areas over waterproofing membranes
• Colour and safety-marking coats on traffic deck systems

Performance Highlights

Surface Preparation & Application

Apply only over a fully cured, approved Tremco base coat. The base coat surface must be clean, dry, and free of contamination. Mix components thoroughly at the ratio specified in the current TDS using a low-speed mixer. Apply by roller or squeegee at the specified film thickness. Allow adequate cure before opening to traffic. Refer to the current Tremco TDS and system specification for mixing ratios, coverage rates, recoat windows, and cure times.

Limitations

• Must be applied over a compatible, approved Tremco base coat — not for direct application to concrete.
• Do not apply to damp, contaminated, or incompletely cured base coat surfaces.
• Do not apply outside recommended temperature and humidity ranges per the TDS.
• Colour availability subject to stock — confirm with Canopus Supply before specifying.

Storage & Shelf Life

Store in original, unopened containers in a cool, dry, ventilated area away from direct sunlight and heat. Confirm shelf life and storage conditions against the product label and current SDS.

Health & Safety

Read the current Safety Data Sheet (SDS) before use. Contains isocyanate components — wear appropriate gloves, eye protection, and respiratory protection. Ensure adequate ventilation during application and cure. Refer to the SDS for full hazard classification and first-aid measures.

Frequently Asked Questions

What base coat is Vulkem 951NF compatible with?

Vulkem 951NF is designed for use over Tremco Vulkem 350NF, 360NF, and other approved Tremco base coats as part of a complete traffic deck system. Always confirm the full system specification with the current Tremco TDS or Canopus Supply before application.

Can Vulkem 951NF be used on exposed outdoor decks?

Its aliphatic polyurethane chemistry is formulated for UV stability on exposed, sunlit surfaces such as podium decks, ramps, and open-air parkade levels. Confirm suitability for your specific exposure conditions against the current TDS.

Is it suitable for vehicular traffic?

When applied as part of an approved Tremco traffic deck system over a compatible base coat, Vulkem 951NF is designed for vehicular traffic applications. Confirm traffic load ratings and system requirements against the current TDS and project specification.

What colours are available?

Multiple colours are available to support traffic marking and architectural requirements. Contact Canopus Supply to confirm current colour availability and lead times before specifying.
