For marble, natural and engineered stone (MN). Lithofin MN Stain-Stop 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 therefore no longer absorbed by the surface, but remain on the surface (12 to 48 hours 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. 

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 the product 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 with a polishing machine and a white pad. 

Attention! The liquid product must penetrate into the stone. Do not allow the product to dry on the surface.

Please Note: Non-absorbent or damp surfaces cannot be impregnated. Glass, ceramics, and surfaces sensitive to solvents (varnishes, wood, etc.) must be protected against splashes.

Application Temperature: The temperature of the surface should be between 10°C and 25°C. Switch off under floor heating.
Drying Time: After approx. 2 hours surface will be dry and ready to be stepped on carefully. The drying process will be complete after 24 hours, do not cover or use suction lifters during this time. Wipe up any spills immediately. The full effectiveness of the impregnator is reached after 5 days. 
Coverage Estimates: 
- Polished Surfaces: 12 to 15 m²/L
- Very Dense Stones: up to 40 m²/L
- Rough/Honed Granite: 5 to 7 m²/L
- Porous Sandstone: 3 to 6 m²/L
Storage: Closed, cool and dry up to 3 years. Open containers should be used without delay.
