LIQUID FOIL Waterproof Tanking Kit – 4.5kg Wet Room & Shower System with Primer
LIQUID FOIL Waterproofing Membrane is a ready-to-use, one-component elastic tanking compound designed for reliable waterproofing of walls, floors, and ceilings in both internal and external environments.
This complete Waterproof Tanking Kit includes 4.5kg LIQUID FOIL, primer, 10m sealing tape, corners, and pipe collars, making it an ideal all-in-one solution for showers, bathrooms, wet rooms, terraces, balconies, and garages.
Especially effective on plasterboard, plywood, and tile backer boards prior to tiling, the system can also be applied to concrete, plaster, and wood. Once cured, it forms a durable, frost-resistant waterproof barrier that seals hairline cracks and reduces the risk of tile cracking caused by thermal movement.
