Tremco Vulkem® 350NF | Single-Component Urethane Waterproofing Base Coat
Single-Component Low-Odor Low-VOC Urethane Waterproofing Membrane — Roller & Self-Leveling Grades | Brand: Tremco
Vulkem® 350NF Base Coat is a single-component, low-odor, low-VOC, urethane membrane that bonds firmly to clean, dry concrete, plywood, and metal. It retains its integrity even if substrate movement causes hairline cracks of up to 1.5 mm. If cut or damaged, Vulkem 350NF will prevent water migration between it and the substrate. Available in Roller (R) and Self-Leveling (SL) grades for vertical and horizontal applications.

Frequently Asked Questions
What is the difference between Vulkem 350NF Roller and Self-Leveling grades?
The Roller (R) grade is formulated for application by roller on vertical, sloped, or horizontal surfaces. The Self-Leveling (SL) grade flows to a flat, uniform surface on horizontal applications with minimal tooling. Select the grade based on the surface orientation and project requirements.
Can Vulkem 350NF bridge cracks in the concrete substrate?
Yes. Vulkem 350NF retains its integrity over hairline cracks up to 1.5 mm. For larger cracks or structural movement, consult Tremco for the appropriate system specification.
