Product Details
Vulkem H2 Rapid: Professional Rapid-Cure Waterproofing Membrane
Vulkem H2 Rapid is a high-performance, single-component, water-based acrylic waterproofing membrane specifically engineered for the modern construction pace. By incorporating advanced micro-fibre technology, this membrane provides superior tensile strength and simplifies the process of achieving the required wet film thickness. It is designed primarily for non-trafficable, internal, and covered external wet areas where speed, reliability, and safety are paramount.
Key Features & Benefits
- Rapid Turnaround: Engineered for efficiency, the membrane is ready for tiling in as little as 5 hours, significantly reducing project downtime.
- Regulatory Compliance: Fully compliant with AS 4654.1 and AS 4858, ensuring it meets the stringent requirements of the National Construction Code (NCC) of Australia.
- Advanced Chemistry: The latex-based formula supports direct-stick tile applications and ensures that once fully cured, the membrane will not re-emulsify when exposed to water.
- Contractor Safety: Low-VOC and low-odour properties make it ideal for use in confined spaces with limited airflow, such as small bathrooms or laundries.
- Easy Maintenance: Water-based formulation allows for easy clean-up of tools and accidental spills without the need for harsh solvents.
Ideal Applications
Vulkem H2 Rapid is versatile and formulated for a wide range of residential and commercial wet areas, including:
- Bathrooms & Showers: Reliable containment for high-moisture zones.
- Kitchens & Laundries: Protection for splash-prone utility areas.
- Balconies: Effective waterproofing for covered, non-trafficable external platforms.
- Internal Tiled Areas: Any indoor space requiring a robust water barrier beneath a finished floor.
Application & Usage Guide
1. Substrate Preparation
For successful adhesion, surfaces must be clean, dry, and free of contaminants like oil, grease, or loose particles.
- Concrete: Must be cured (min 20 MPa) with moisture content below 4.5%. Rough surfaces should be leveled, and 90° transitions should be modified to 45° cants.
- Metal: Surfaces should be sand-blasted to "Near White Metal" standards (AS1627.4).
- Cracks: Shrinkage cracks >1.6mm must be ground out, cleaned, and filled with an appropriate polyurethane sealant (like Dymonic 100) before the membrane is applied.
2. Priming
Vulkem H2 Rapid requires a primer on porous substrates.
- Use TREMproof WB Primer for general porous surfaces.
- Use TREMproof 200EC if a vapour barrier is required.
- Use TREMprime Non-Porous Primer for metal or PVC surfaces (such as puddle flanges).
