Mapei’s fast track tanking kit – Mapelastic AquaDefense – reportedly provides rapid waterproofing for wet rooms, bathrooms, and showers. The ready-to-use kit is designed for all types of ceramic, stone, and mosaic installations in areas in contact with moisture and running water.
Each Mapei tanking kit includes Mapelastic AquaDefense flexible, waterproofing membrane, and Mapeband PE 120 – a deformable, elastic waterproof tape made from polyester mesh and PVC fabric.
During application, Mapeband PE 120 is used to waterproof corners between adjacent walls, and between walls and floors. Working together, the kit creates a highly waterproof system. After the first coat of membrane, a second coat can be applied one hour later. On sound dry screeds, with less than 3% residual moisture, surfaces are ready to tile – without the need to prime – after just four hours. Floor tiles can be opened to light foot traffic in as little as six hours, using a suitable Mapei rapid set adhesive and grout.
Mapelastic AquaDefense is solvent-free and easy to apply with a roller, brush, or trowel. It can be applied onto concrete, cementitious screeds and screeds made using special binders – including Mapei Topcem, Topcem Pronto, Mapecem, and Mapecem Pronto – internal plasterboard, existing ceramic, terrazzo and stone surfaces, and cementitious render. As well as wet rooms, bathrooms and showers, the kit is also suitable for use in laundry rooms, and in damp environments including saunas and other appropriate spa settings.
