Lithofin Protector for (quartz) composite and artificial stone

Your quartz-composite kitchen island shows dark rings every time red wine sits for longer than a few minutes. Bathrooms with matt porcelain vanities pick up greasy fingerprints that refuse to wash off. Protector 345 stops the stains before they start.

What Protector Does

Protector is a neutral solvent-based impregnator for low-porosity engineered and natural stone. Its pH≈7 carrier drives 2-3 % fluoropolymer solids 1-2 mm into the surface, lining the micro-capillaries with a 115° water-contact-angle film that blocks oil and dye molecules for up to 24 months.

When to Use

• Freshly installed quartz-composite worktops - apply undiluted (1:0) before first use.
• High-traffic hotel vanities made from porcelain - one flood coat undiluted, repeat after 10 min.
• Polished granite reception desks exposed to coffee - single wipe-on coat, undiluted.
• Textured ceramic splash-backs that trap grease - spray undiluted, back-roll immediately.
• Concrete countertops requiring hydrophobic protection - liberal undiluted application followed by wet-on-wet top-up.

How to Apply

1. Ensure the surface is dry (<12 % moisture) and clean; pre-wash with Lithofin PRO Clean & Care and wait 24 h.
2. Saturate a lint-free cloth or low-pressure sprayer with Protector and spread a wet film; consumption 35 ml/m².
3. After 10 min, redistribute excess using a new cloth until the surface looks even and streak-free.
4. Let air-dry 60 min; avoid water, oil, or foot traffic for the full 24-h cure.

Typical coverage: 25-40 m²/L on polished quartz, 15 m²/L on textured concrete. Touch-dry in 1 h, fully cured in 24 h at 20 °C.

Surface Compatibility

Protector shows excellent results on quartz composite because its low-viscosity carrier matches the material’s Mohs 7, low-porosity matrix. It also bonds well to acid-resistant granite, porcelain, ceramic, and high-porosity concrete without altering gloss. Do not use on waxed, acrylic-coated, or any surface sensitive to solvents.

Choosing the Right Product

For routine neutral cleaning after sealing, use Lithofin PRO Clean & Care. For deeper impregnation of very absorbent natural stone, use Lithofin PRO Stain-Stop.

Pro Tips

• Warm the room to 18-25 °C; higher temperature halves cure time by accelerating solvent flash-off.
• Always double-wipe polished slabs; leaving residue can cut stain repellency by 30 %.
• Re-test after one year: place a water droplet for 10 min; if the stone darkens, reapply Protector.
