Description

Vulkem® 351NF is a low-VOC, two-component, aliphatic polyurethane top coat designed for use over Vulkem 350NF in pedestrian waterproofing systems. When combined with the recommended aggregate, it creates a durable, UV-resistant, and skid-resistant surface ideal for foot traffic and exposed environments. It forms a strong interlaminate bond with Vulkem 350NF to complete a seamless, elastomeric waterproofing system.

Features & Benefits

  • UV Resistant & Durable: Withstands exposure to sunlight and harsh weather
  • Low VOC Formula: Safe for occupied buildings and odor-sensitive projects
  • Aesthetic Finish: Available in a variety of colors for architectural appeal
  • Slip Resistance: Skid-resistant surface achievable when applied with aggregate
  • Strong Intercoat Bonding: Excellent adhesion to cured Vulkem 350NF base coat
  • Recoatable & Compatible: Integrates with Tremco’s full waterproofing system
