Everbuild Aquaseal Waterproof Tanking membrane is the ideal product for use on showers, wet rooms and wet zones in bathrooms when waterproofing before tiling.

Best Uses

Aquaseal forms a permanently flexible watertight membrane and is non hazardous and solvent free. Aquaseal Waterproof Tanking Membrane can be used with underfloor heating, on plasterboard, MDF, Plywood, Cementitious Boards, Blockwork, Concrete and Speciality Wet Room Boards. Aquaseal Waterproof Tanking membrane is easy to apply by brush, is quick drying and can be tiled after 12 hours. Tested to BS/EN 14891.

The Aquaseal Waterproof Tanking Membrane can be used on its own in many applications where a flexible watertight membrane is required, or in conjunction with Aquaseal Tanking Primer, Aquaseal Tanking Tape and Aquaseal Tanking Drain Mat, as part of the Aquaseal Wet Room System, to provide a 100% waterproof membrane to conventional plaster and timber based boards. It can be applied to all common building substrates such as plasterboard, MDF, plywood cementitious boards, blockwork, concrete & speciality wet room boards.

  • Can be used on most common building surfaces
  • Ready to use, no diluting necessary
  • Easy to apply by brush
  • Non-hazardous, solvent free
  • Can be tiled over after 12 hours


Surfaces should be clean, dry and dust free. Prime porous and semi porous substrates with Aquaseal Tanking Primer (where this is not available use a suitable SBR Bonding Agent, such as Everbuild 503 SBR Bond, diluted with 4 parts water) and allow to dry for one hour before applying the membrane.

Apply by brush (at least 3" wide) in two coats which should be applied in different directions at right angles to each other to ensure full surface coverage is achieved with no weak spots. Apply the first coat horizontally and allow to dry for a minimum of 6 hours. Then apply the second coat vertically.

Pay careful attention to edges and corners to ensure that the coverage in these areas is always consistent as these are the potential weak spots where leakage could occur. We always recommend the use of Aquaseal Tanking Tape on corners and board joints prior to applying the membrane to ensure the integrity of the watertight seal. Aquaseal Tanking Tape provides cross directional movement at corners and on board joints and is available in 10 Metre rolls. The Aquaseal Tanking Drain Mat is also recommended around the drain outlet, which is the area most susceptible to leaks. As a guide the finished two coat system, when dry, should have a minimum thickness of 1mm. Allow the second coat to dry thoroughly for up to 12 hours before tiling.
