K11 Waterproof Coating
K11 Waterproof Paint for Concrete Walls provides positive side waterproofing to all common building substrates that require protection from topside water exposure before the installation of tile or stone. K11 Waterproof Paint for Concrete Walls is a two-component system consisting of a solvent-free, acrylic based liquid combined with a Portland cement-based powder.
K11 is a two-component polymer and modified cement based waterproof material. It can permeate into the inside pore of the substrate, then form into waterproof crystals. These crystals will stick together and become a part of substrate. It will be an effective waterproof after drying. No need to do a protective layer. You can do next construction directly on it. It is suitable for all kinds of construction substrate..
