Lithofin KF Stain-Stop is a high-performance protective sealer specifically formulated for owners of absorbent unglazed ceramic, terracotta, and quarry tile surfaces looking to prevent stubborn stains. By penetrating the tile structure, it creates an invisible shield against water, oil, and grease, preserving the natural aesthetic of your floors without adding an artificial sheen. While it offers superior long-term protection for both indoor and outdoor spaces, users must be mindful that the application process requires careful temperature control and a mandatory 24-hour curing period to reach peak efficacy.

No, this product is specifically designed for absorbent, unglazed surfaces. It will not penetrate glazed tiles.
While it dries to the touch in 30-40 minutes, you should wait the full 24 hours for the sealer to achieve full protective effectiveness.
No, because the sealer penetrates the stone rather than forming a film on top, it does not alter the surface grip.
Lithofin KF Stain-Stop is designed to be invisible and should not alter the natural color of your tiles.
It is best to avoid direct sunlight during application to ensure the product remains within the recommended 10-25°C temperature range for proper curing.
You likely left too much excess product on the surface. Wipe the area with a clean cloth while the product is still fresh, or use a small amount of mineral spirits if it has already hardened.
The tile may be non-absorbent or already sealed. Verify the material type; this product is intended for porous, unglazed surfaces only.
Before starting, ensure the application area is maintained between 10-25°C. If you have underfloor heating, it must be turned off until the surface has cooled completely to room temperature. Apply the sealer evenly using a brush or a specialized applicator. After 30-40 minutes of drying time, any excess product remaining on the surface should be removed with a lint-free cloth to prevent smearing. The surface should remain untouched and kept dry for at least 24 hours to ensure the protective agents fully bond with the ceramic material.
