An acrylic-cement based, grey, flexible, waterproofing membrane, Dampfast prevents surface water penetration. It enables a convenient installation process as it supplants the need for a reinforcement layer, can be applied easily with a damp brush or roller, and can be cured in approximately 6 hours 20°C, saving time and making it possible to tile on the same day. Dampfast is perfect for waterproofing shower recesses, laundries, terraces, balconies, concrete roofs, water tanks, cement toppings and even planter boxes. Dampfast can also be used in tanks – where conventional acrylic membranes would fail. It thus suits water tanks, fishponds and planter boxes.
