B-Chem Bwr - Back Treatment for Natural Stones Against the Rise Of Dampness

Product category: protectors

Description: BWR is a water-repellent emulsion with acrylic reactive resins melted in water. Its special formula, developed for the

protection of the back side of tiles, makes a film with very special chemical and mechanical characteristics. The product is applied in the back side of those materials subject to the rise of salts, dampness, oxidation reactions, etc… before their laying. The film made by the product only allows a slight rise of damp, so it acts as a protection membrane, avoiding the unpleasant inconveniences caused by the rise of dampness. BWR can also be used as a binder for concrete mixtures, in order to have mortars with better chemical-mechanical resistance and to increase adhesion to old stones.
