Collection: Ultraflex PU Liquid Coating

ULTRAFLEX is a high-performance liquid membrane designed for waterproofing a range of surfaces, including both new and existing flat roofs, balconies, terraces, walkways, and gutters.

Solvent Based Polyurethane Waterproofing

This solvent-based polyurethane system is highly elastomeric and safety-certified, enabling single-layer application with excellent adhesion across a variety of substrates such as OSB board, plywood, GRP roofs, bituminous membranes, asphalt, metals, brick, concrete, and wood.

No Catalysts or Primers Required

The product is ready to use straight from the tin, eliminating the need for mixing or catalysts, which reduces waste and prevents mistakes on site. For faster curing, ULTRAFLEX can be combined with Quickcure Accelerator. On upstands or vertical areas, Tixal Thickener can be used for added coverage and stability. ULTRAFLEX PU Liquid coating typically does not require a primer for the majority of substrates and is covered by both BBA and ETE certification for a lifespan exceeding 25 years.
