A special impregnation which strongly repels water, grease and oil. Used to protect flooring, table tops and working surfaces made of absorbent natural and artificial stone (s.a. marble, Solnhofer stone, sandstone, fine stoneware). For indoors and outdoors. Prevents the stone from staining spots or makes removing of spots much easier, the stone remains capable of breathing. The protective effect already begins after some minutes and is fully effective after 2-3 hours. Normally the colour of the stone remains unchanged. Special substances work against a laminar wetting through liquid drops. Ball-shaped liquid pearls which lie only selectively on top of the stone surface, run off the surface.
