Keep your tile joints looking like new with Lithofin KF Grout Protector.

This high-performance, solvent-free impregnator is designed to protect absorbent, porous cement-based grout joints from staining. By penetrating deep into the grout, it creates an invisible barrier that repels oil, grease, and water, making it significantly easier to remove dirt and spills before they soak in.

Unlike surface coatings that can peel, this impregnator works from within, leaving the appearance of the grout largely unchanged (though it may slightly darken the color, enhancing the contrast). It is ideal for use in hygiene-critical areas like kitchens and bathrooms, where grout is most vulnerable to discoloration from cooking fats and soap scum.

Why use Lithofin KF Grout Protector?

• Invisible Shield: Repels water and oil without forming a shiny film or changing the texture of the grout.

• Easier Maintenance: Prevents dirt from penetrating deep into the joint, allowing for effortless daily cleaning.

• Long-Lasting: A single application provides durable protection for years, keeping your sanitary and kitchen areas hygienic.

Directions for Use:

1. Ensure grout is clean and dry (use Lithofin KF Grout Cleaner first if restoring old grout).

2. Apply generously and evenly using a fine brush or roller directly onto the grout lines.

3. Allow to soak for approx. 20 minutes.

4. Wipe away all excess liquid from the tile surface before it dries to avoid streaking.

5. Allow to dry for 24 hours before wetting.

• PREVENTS STAINING: Creates a powerful hydrophobic barrier against oil, grease, water, and dirt penetration in porous cement grout.

• KITCHEN & BATHROOM ESSENTIAL: Ideal for "splash zones" behind hobs, sinks, and showers where grout discoloration is common.

• INVISIBLE PROTECTION: Does not form a surface film or shine; penetrates deep to protect from within without altering the grout texture.

• SOLVENT-FREE FORMULA: Odourless and safe for use in confined indoor spaces like shower cubicles and unventilated bathrooms.

• COVERAGE: 500ml treats approximately 10m² of tiled surface (depending on tile size and grout width).
