Vulkem 350R – Versatile, Rollable Polyurethane Membrane for Above-Grade Waterproofing

A flexible waterproofing solution for a wide range of commercial and residential applications. Vulkem 350R is a low-VOC, rollable-grade, polyurethane waterproofing membrane designed as a high-performance base coat. Its versatile nature allows it to be used as a standalone membrane in non-UV exposed, non-traffic areas like plant rooms, or as the crucial first layer in a fully finished system when topped with a Vulkem polyurethane top coat for balconies and podiums.

Tested to AS4654.1 for compliance with the National Construction Code (NCC), Vulkem 350R provides a reliable, easy-to-apply barrier that is mildew-resistant and fully compatible with the broader Tremco sealant range, ensuring complete system integrity.

Key Features & Benefits:

• Rollable Application: Specifically formulated for easy roll application, simplifying installation on large, open areas like podiums and roofs.
• System Versatility: Use as a cost-effective standalone membrane in protected areas, or as a base coat for a full top-coated system with custom slip ratings.
• Low VOC Formulation: Reduces environmental impact and improves job site air quality compared to traditional solvent-based membranes.
• AS4654.1 Compliant: Independently tested to meet Australian standards for external waterproofing, ensuring NCC compliance.
• Mildew & Fungus Resistance: Protects the membrane and substrate from biological growth, ensuring long-term durability.
• Single-Component Convenience: Ready-to-use straight from the pail, eliminating on-site mixing and ensuring consistent performance.
• Full System Compatibility: Re-coatable and designed to work seamlessly with Vulkem top coats and Tremco sealants.

Primary Applications:

• Podium Decks & Balconies: Base membrane for finished pedestrian areas (requires Vulkem top coat with aggregate for slip resistance).
• Protected Areas: Standalone membrane for mechanical plant rooms, lift overruns, and other non-UV, non-traffic areas.
• Roof Terraces & Recreational Areas: The foundational waterproofing layer for amenity spaces.
• Car Park Decks & Ramps: Durable base for areas requiring a tough, waterproof seal.

Usage Guidelines:

• Standalone Use: Suitable for internal or covered areas with no UV exposure or foot traffic.
• Full System Use: Must be top-coated with a Vulkem polyurethane top coat (e.g., Vulkem 350T) for external, UV-exposed, or pedestrian traffic areas. Aggregates can be broadcast into the top coat to achieve specific slip ratings.
