Lithofin MN Stain-Stop

Description 

A special product from the LITHOFIN MN program for marble, natural, and concrete stone. Lithofin MN Stain-Stop contains high-quality water- and oil-repellent impregnating agents based on siloxane, dissolved in solvents. It is thin-liquid, colorless, and ready to use.

Properties 

Lithofin MN Stain-Stop penetrates the surface and forms an ultra-thin, invisible layer in the capillaries. This ensures that oils and greases are not absorbed but remain on the surface—for carbonate stones (marble, limestone, etc.) approx. 12–48 hours, for silicate stones (granite, gneiss, etc.) up to approx. 60 hours. Within that time, oils can be removed without leaving stains. Effectiveness depends on the substrate and the amount of product absorbed. The characteristic appearance of natural stone remains unchanged. In some stones, the color may deepen slightly, especially when applied generously to darker stones. Water absorption is greatly reduced, while water vapor permeability is largely maintained. The active ingredients are UV-resistant and do not yellow.

Application 

For user-friendly, invisible stain protection treatment of almost all types of natural stone with polished, honed, or rough surfaces, as well as for concrete and engineered stone (composite). Particularly suitable for walls and floors in kitchens and bathrooms, and other stain-sensitive surfaces such as countertops, windowsills, and tabletops.

Note: The stone remains sensitive to acids.

Application Instructions 

If you have not used this product before, test on a small sample area first. Suitable tools: cloth, brush, or sponge. The surfaces to be treated must be completely dry, clean, and free of stains. For large areas: work in sections of approx. 10–15 m². Apply Lithofin MN Stain-Stop generously until the surface is moist. Allow the product to act for 15 minutes. Redistribute excess product and remove puddles and streaks. On very absorbent material or dry spots, it may be necessary to apply more product. Remove all residues within 30 minutes using a dry cloth. On larger surfaces, remove excess product with a squeegee and buff with a machine (white pad or lambswool).

Important: The liquid product must penetrate the surface. Do not allow it to dry on the surface.

Attention: Non-absorbent or damp surfaces cannot be impregnated. Protect glass, ceramics, and solvent-sensitive surfaces (lacquers, wood, etc.) from splashes. Only walk on treated, still-wet surfaces wearing clean overshoes. Tools can be cleaned with solvent.

Application Temperature: The surface temperature must be between 10 °C and 25 °C. Lower or turn off underfloor heating.

Drying Time: After approx. 2 hours, the surface is cautiously walkable. Fully dry and effective after 24 hours. During this period, avoid using suction cups for transport, do not cover, and immediately remove spilled liquids. Full effectiveness is reached after 5 days.

Coverage: Depends on the absorbency of the surface. A second coat reduces consumption by half.

Guidelines: Polished stone surfaces: approx. 12–15 m²/litre

               Very dense stone: up to 40 m²/litre

               Split/rough granite: approx. 5–7 m²/litre

               Porous sandstone: approx. 3–6 m²/litre
