Lithofin Stainstop 'W' is ready-to-use and contains highly active water and oil repellent polymers and additives. This solvent-free special impregnator effectively protects surfaces against the penetration of oil, grease, dirt and water, and it largely prevents staining. The product penetrates into the surface and forms an extremely thin, invisible film in the capillaries. The appearance of the treated surface is either unaffected or only slightly altered. Use on absorbent surfaces (e.g. sandstone), rough concrete stone and polished stone. Facilitates maintenance on stain sensitive surfaces, such as floors in kitchens and dining areas, tables, counter tops etc.
