Achieve rapid, robust, and compliant waterproofing for diverse internal and external applications with a cutting-edge, water-based membrane. It forms a rain-resistant finish in 3 hours, withstands early ponding water, and offers outstanding weather and UV resistance. This ensures projects stay on schedule, even when conditions are less than ideal.

Why this product exists

Gripset Xpress Multi Pro overcomes common frustrations with traditional waterborne waterproofing systems. Lengthy drying times, re-emulsification after early ponding, and washout from unexpected rain can derail a project. This advanced, water-based membrane delivers an ultra-rapid cure, forming a rain-resistant barrier within 3 hours and resisting early ponding without re-emulsification or blistering. It also provides a safer, solvent-free alternative to hazardous solvent-based polyurethane membranes, pushing the boundaries of waterproofing technology for the built environment.

The numbers that matter

Waterproofing decisions are driven by performance and project timelines. Gripset Xpress Multi Pro delivers a rain-resistant finish in 3 hours, accelerating project timelines and reducing weather-related delays. Its elastomeric Class III elongation of over 300% accommodates significant substrate movement, minimising the risk of membrane failure over time. A low water vapour transmission rate of 6 g/m²/24 hours ensures minimal moisture ingress. This membrane is compliant with AS 4858 for internal wet areas and AS 4654.2 for external above-ground use, providing a robust solution for diverse applications.

What it's like to use

Applying Gripset Xpress Multi Pro involves standard brush or roller methods. Surfaces must be clean, sound, and properly primed. For porous substrates, use Gripset GP Primer. Non-porous surfaces require Gripset OP Primer. Critically, for green or damp substrates, the system supports specific primers like Xpress Primer H2O Plus or Gripset E60 to manage residual moisture and reduce waiting times. Recoat times are 1-2 hours. Cleanup is straightforward with water while the membrane is wet; dried product requires mechanical removal.

Where this product excels

This membrane is engineered for demanding waterproofing scenarios, especially where rapid return to service and long-term durability are critical. It excels as an exposed membrane finish on roofs and parapets, or under screeds and toppings, providing robust protection against constant weather and UV exposure. It is also an effective solution for internal wet areas, including bathrooms, laundries, and tiled floors. The product is also specified as a liquid membrane sealant option for critical detailing on balconies, podiums, door/window reveals, and flashings, providing a reliable barrier at these vulnerable points.

How it fits in a real system

Gripset Xpress Multi Pro is often the final liquid membrane layer in a comprehensive waterproofing system. For balconies and decks, it frequently follows the application of other critical components like Prefabricated Corners and Gripset 38FC Waterproofing Membrane, ensuring a complete and integrated waterproofing envelope. This placement means it seals and protects the entire system against environmental exposure, providing the necessary weather and UV resistance.

Choose this when

  • Project timelines are tight: Its 3-hour rain resistance allows rapid progress and reduces weather-related delays.
  • Exposed external areas require robust protection: Use it on roofs, parapets, or balconies where constant UV and weather exposure demands high durability.
  • You need a solvent-free solution: Opt for this product for a safer alternative to traditional solvent-based membranes.
  • Detailing vulnerable points: It functions effectively as a liquid membrane sealant option for flashings, reveals, and podiums.

Don't use this when

  • Not for: Areas where solvent or petroleum-based products may be spilled, as this can compromise the membrane.
  • Not for: Situations involving negative hydrostatic pressure.
  • Not for: Application when rain is imminent or when surface temperatures are below 5°C or above 30°C.
  • Avoid: Using solvent-based finish coatings directly over this membrane.

This membrane is tested and certified to Australian Standards, meeting AS 4858 for internal wet areas and AS 4654.2 for external above-ground applications. This compliance ensures the product adheres to strict performance requirements for waterproofing, providing confidence in its suitability and long-term integrity.
