Promac Rubber Duck Super Cold RBE is a single-component rubberised bitumen waterproofing product developed to create a tough, flexible, and watertight barrier against liquid water and water vapour. It is suitable for damp proofing walls, floors, and foundations, and can also be used on ponds, dams, water features, and roofs. Once dry, it forms a durable film that can accommodate small movement cracks, resist abrasion and impact, and withstand high temperatures without running or slumping. Available in 1L, 5L, and 20L, it is a practical waterproofing solution for both maintenance and larger-scale sealing applications.
