Lithofin MN Fleckstop is a ready-to-use, solvent-based impregnating sealer designed to protect natural stone, artificial stone, and absorbent concrete surfaces from water, oil, and grease stains.

The product penetrates deep into the surface, forming an invisible, UV-resistant protective barrier that significantly reduces absorption while allowing the stone to breathe. Spilled liquids remain on the surface for a short time and can be wiped away without leaving stains.

Lithofin MN Fleckstop does not change the appearance of the surface and will not yellow over time, making it ideal for both indoor and outdoor applications on sensitive stone surfaces.

⚠️ Note: The natural stone’s sensitivity to acids remains unchanged.

Instructions for Use

1. Ensure the surface is absorbent, clean, and completely dry.
2. Apply using a cloth, brush, or sheepskin applicator.
3. For large areas, work in sections of 10–15 m².
4. Apply evenly until the surface appears visibly wet.
5. Allow to penetrate for approx. 15 minutes.
6. Redistribute excess product and remove puddles.
7. Wipe off any remaining excess within 30 minutes using a dry cloth.
8. On large surfaces: remove excess with a rubber squeegee, then a monobrush with a white pad or sheepskin.
9. Do not allow excess product to dry on the surface.

🔎 Always test on a small, inconspicuous area before full application.

Coverage / Yield

Coverage depends on the absorbency of the surface.

• Highly absorbent surfaces require more product
• Consumption is reduced by approx. 50% on the second application
