It is formulated to retain integrity over hairline cracks up to 1.5 mm. If cut or damaged, Vulkem 350NF is designed to resist water migration between it and the substrate. Available in Roller (R) and Self-Leveling (SL) grades. Confirm suitability against the current TDS, SDS, and project specification before use.

Performance Highlights

Key Characteristics

• Low Odour & Low VOC: Formulated for use in enclosed parkades and occupied structures with appropriate ventilation; confirm ventilation requirements against the SDS.
• Crack Bridging: Designed to retain integrity over hairline cracks up to 1.5 mm; confirm limitations for larger cracks or structural movement against the TDS.
• Water Migration Resistance: Formulated to resist water migration between membrane and substrate if cut or damaged; confirm performance requirements against the TDS.
• Single-Component: No mixing required — apply directly from the pail; confirm application temperature and humidity requirements against the TDS.
• Two Grades: Roller grade for vertical and sloped surfaces; Self-Leveling grade for horizontal applications — confirm grade selection against project requirements.
• Multiple Substrates: Designed for concrete, plywood, and metal; confirm substrate preparation requirements against the TDS before application.

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 surface orientation and project requirements, and confirm against the current TDS.

Can Vulkem 350NF bridge cracks in the concrete substrate?

Vulkem 350NF is formulated to retain integrity over hairline cracks up to 1.5 mm. For larger cracks or structural movement, consult the current Tremco TDS and project specification for the appropriate system approach.
