Description
DEFENDER S is a product based on silicone catalyzed resins dissolved in solvent mixture, for the hydrophobic protection of the joints of terraces and balconies. Thanks to its particular composition and to its low viscosity, the product shows a high degree of penetration and an important and deep water-repellent action.
The elasticity of the silicone resins allows the product to hydrophobise also the joints where there is presence of small cracks (not greater than one millimeter of thickness). The water repellent action will prevent water to penetrate into the joints and it will prevent the destruction by frost during the winter and the formation of mould. DEFENDER S does not change the color appearance of the treated materials and does not substantially change its breathability. DEFENDER S also shows a high resistance to UV rays.
