Mapei AquaDefense 7.5kg Tanking Kit

Providing everything needed to create a fully waterproofed substrate before tiling in showers, wet rooms, and balconies.

Based on Mapelastic Aquadefense — a ready-to-use, single-component liquid membrane — the kit delivers a 100% watertight seal that is strong, durable, and dries fast enough to tile after just four hours, making it well suited to time-sensitive installations.

Compatible with all AKW shower formers, the membrane can also be reinforced with Mapetex SEL fabric (sold separately) where an anti-fracture layer is required, such as over movement-prone substrates.

Technical Specifications

Key Features

• Complete waterproofing kit — Primer G, Aquadefense membrane, and Mapeband seam tape included; no additional waterproofing materials required for a standard installation
• 100% watertight — strong and durable — flexible membrane maintains a continuous, resilient seal that holds up to long-term wet area use without bridging joints or pinholing
• Ultra-rapid drying — tiling can begin after just four hours, reducing overall project time versus slower-curing alternatives
• Ready to use, one component — no mixing required; apply straight from the drum, reducing the risk of preparation errors on site
• Highly versatile — suitable for showers, wet rooms, and balconies, both interior and exterior, giving broader application than shower-only products
• AKW former compatible — specified for use with all AKW shower trays, making it a natural pairing for AKW former installations
• Anti-fracture capability — embed Mapetex SEL (sold separately) into the wet membrane over movement joints or cracked substrates for added structural resilience
