3 great products to choose from. Lithofin Stainstop PLUS is the most popular choice because it offer protection from water and oil based stains unlike Lithofin Colour-Intensifier which only protects the sealed surface from water based staining components. However, these 2 sealers provides colour enhancing properties to the substrate being sealed giving it the 'wet look'. It generally darkens the material most often highlighting the characteristic and natural beauty of stone. Tenax AGER is also colour enhancing and offers protection from both water and oil based stains. A great alternative.
