Hydrophobic additives ensure water-resistance, thus eliminating clogging and significantly improving hygiene of ceramic surfaces! It is suitable for wall tiles and floor tiles mainly in bathrooms, kitchens, and other areas which have sanitary demands. In addition, it can be applied on balconies, heated floors, restaurants, stores, and similar areas. It is especially used for jointing SDI panels when laying noise-dampening floor tiles. It is not suitable for dilatation joints and surfaces where chemical resistance is required.
