Everbuild Sika 487333 Aquaseal Waterproof Tanking Membrane – 5 Litre Liquid Membrane

Everbuild Sika 487333 tanking membrane is a ready-to-use liquid waterproofing compound for creating a flexible waterproof barrier on walls and floors before tiling. Designed for wet areas, it helps protect backgrounds from water ingress in showers, wet rooms and wet zones, and can also be used in other water-exposed areas such as balconies and partially covered external areas.

Applied as a two-coat system by brush, the 487333 membrane is solvent-free and non-hazardous, with a fast turnaround that allows tiling to start after suitable drying time.

Key Features

• Two-coat brush application: Applied in two coats at right angles to help achieve consistent coverage with fewer weak spots.
• Permanently flexible waterproof barrier: Forms a watertight membrane designed to accommodate minor movement under tiled finishes.
• Ready to use: No mixing or dilution required for the membrane, helping to speed up preparation on site.
• Solvent-free formulation: Non-hazardous, low-odour waterproofing designed for indoor use as well as suitable external protected areas.
• Broad substrate suitability: Suitable for common building backgrounds including plasterboard, MDF, plywood, cementitious boards, blockwork, concrete and speciality wet room boards.
• Fast turnaround: Minimum 6 hours drying between coats (conditions dependent), with tiling possible after the second coat has dried.
