Lithofin MN Stain-Stop penetrates into the surface and coats the capillaries with an extremely thin, invisible film. Oil, grease and water are therefore no longer absorbed by the surface, but remain on the surface (12 to 48hours on polished marble and limestone, up to 60 hours on granite and gneiss).

During this time, oil can easily be removed without leaving stains. The effectiveness depends on the amount of product absorbed by the surface. The appearance of the natural stone is not affected. Some stones may become slightly darker in colour. The water absorbency of the stone is greatly reduced; the water permeability is only slightly affected. The product is UV-resistant and does not yellow.
