Larsen Waterproof Tanking Kit is a complete multi-component waterproofing system designed to provide reliable protection in wet rooms, shower enclosures, bathrooms, and other areas exposed to frequent water contact. Ideal for professional tiling installations and refurbishment projects, the system creates a flexible waterproof barrier that helps prevent moisture penetration beneath tiled finishes.

The kit combines a high-performance water-based liquid-applied membrane, self-adhesive butyl sealing tape, and acrylic primer to provide a comprehensive waterproofing solution before tiling. Together, these components create a robust waterproof layer that offers secondary protection against water ingress, helping to safeguard walls, floors, and structural substrates in wet environments.

Designed for quick and straightforward installation, Larsen Waterproof Tanking Kit is suitable for domestic and commercial projects including wet rooms, power showers, bathrooms, sports changing facilities, and shower areas. The easy-to-apply system helps installers achieve professional waterproofing results while reducing installation time.

Providing coverage of approximately 4m² when the membrane is applied in two coats, Larsen Waterproof Tanking Kit delivers dependable waterproof protection and peace of mind before the installation of ceramic, porcelain, natural stone, and mosaic tiles.
