Description

Vulkem® 350NF is a single-component, low-VOC, low-odor polyurethane waterproofing base coat designed for odor-sensitive environments. It cures to form a seamless, rubberized membrane that adheres to concrete, well-anchored AC plywood, and primed metal surfaces. Ideal for use in pedestrian areas, Vulkem 350NF delivers high-performance waterproofing while minimizing disruption to surrounding spaces.

Features & Benefits

  • Low VOC & Low Odor: Ideal for use in occupied or enclosed environments.
  • Durable & Flexible: Maintains performance despite substrate movement and bridges hairline cracks up to 1/16” (1.5 mm).
  • Water Migration Prevention: Maintains adhesion even if damaged or cut.
  • Fast Cure Time: Tack-free in 6–8 hours; walkable in 4–6 hours.
  • Versatile Application: Available in roller-applied (R) and self-leveling (SL) versions for vertical or horizontal surfaces.
  • Recoatable & Compatible: Works with Vulkem topcoats and Tremco waterproofing systems.
