Description Lithofin MN Stain Stop is a special sealing product from the LITHOFIN-Range for marble, natural and engineered stone (MN). It is a ready-to-use, solvent-based impregnator that contains high quality water and oil resistant components. Lithofin MN Stain Stop penetrates into the surface and coats the capillaries with an extremely thin, invisible film. Oil, grease and water are not absorbed by the surface, but remain on the surface (12 to 36 hours on polished marble and limestone, up to 48 hours on granite and gneiss). During this time, oil can easily be removed without leaving stains. The effectiveness of the product depends on the amount of product absorbed by the surface. Lithofin MN Stain Stop does not affect the appearance of natural stone. Some stones may become slightly darker in colour. The product greatly reduces the water absorbency of natural stone and only slightly effects the water permeability. Lithofin Stain Stop is for invisible protection against staining and for facilitating maintenance of all natural stone surfaces, including polished marble. It is UV-resistant and does not yellow. It is perfect for use on wall and floor surfaces in the kitchen and bathroom, as well as on table tops, window sills and other sensitive surfaces. Please Note: marble and limestone will remain sensitive to acid after being treated. Lithofin MN Stain Stop FAQ’s: What’s the difference between an impregnator and a surface or topical sealer? Impregnators, such as Lithofin MN Stain Stop, do not form layers on the surface of the stone. Instead, the active ingredients penetrate into the capillaries and form a durable film inside them. The stone’s appearance generally remains the same and the treatment should last many years as it won’t be worn away. In contrast, surface or topical sealers, form a protective film over the surface of the stone that will need maintaining as it wears down. When should Lithofin MN Stain Stop be applied? Ideally, after installation, once the tiles are clean, fully dry, and prior to grouting. This will seal the sides of the tile as well. Applying at this point will aid the removal of grout residues later and stop any possible staining or picture framing from the grout pigment or moisture. A further application can be made after grouting to seal the grout lines for maximum water and stain resistance. Should Lithofin MN Stain Stop only be applied to the face of a tile? No, the impregnator needs to be applied to the face and edges of the tile before grouting (on new installations) to ensure that there will be no staining from the grout which can lead to discolouration of the tiles. Directions for use: The surface to be treated must be absorbent, clean and completely dry. Suitable application tools: cloth, brush or sponge. Without prior experience or in cases of doubt, try Lithofin MN Stain Stop in an inconspicuous area prior to use. On large surfaces, work in small sections of 10 to 15m². Apply Lithofin MN Stain Stop generously until the surface appears wet. Allow the product to penetrate for approx. 15 minutes. Redistribute the excess product and remove puddles and streaks. On highly absorbent materials or on dry spots more product may have to be added. Remove all remaining product residues within 30 minutes using a dry cloth. On large surfaces use a squeegee to remove excess product with a polishing machine and a white pad. Please note: The liquid product must penetrate into the stone. Do not allow Lithofin MN Stain Stop to dry on the surface. Drying Time: After 30-40 min. surface will be dry and ready to be stepped on. Complete drying process and effectiveness of the impregnation will take approx. 5 days. During this time, do not cover the surface and wipe up any spills immediately. Durability: Lithofin MN Stain Stop lasts up to 5 years on outdoor surfaces. Indoors the durability depends on the care products used. Strong de-greasing or layer forming products are unsuitable. Heavily used surfaces such as kitchen counters and vanity tops should be touched up once a year with the solvent-free Lithofin STAINSTOP W. Advice: immediately remove stain causing substances. For regular maintenance of floors we recommend Lithofin MN Wash & Clean, for kitchen counter tops Lithofin MN Easy-Clean. Coverage: Depends on the absorbency of the stone. Estimates: polished surfaces: 12 to 25m²/litre rough/honed granite: approx. 5-7m²/litre porous sandstone: approx. 3-6 m²/litre Technical Data: Density: approx. 0.8 g/cm³ Flash Point: about 32°C Appearance: colourless Odor: aromatic Reduction of water absorbency: approx. 90-95% Permeability: approx. 80 to 90% Click here to view this product on the manufacturers website.
