Lithofin MN Slate-Oil
Art. 177-11-B
Your slate kitchen countertop looks chalky and washed-out after daily scrubbing. Patio slabs have lost the deep charcoal tone that sold you on slate in the first place. Slate-Oil restores that rich colour in one easy coat.
What Slate-Oil Does
Slate-Oil is a neutral, oil-based colour-enhancing impregnator for slate. The low-viscosity oil (pH 7) penetrates 1-2 mm, filling micro-pores and raising light absorption so colours read darker by up to 30 %. Once cured, the polymerised oil repels water and dirt while allowing vapour diffusion, preventing surface greying caused by capillary moisture.
When to Use
- Interior slate floors in kitchens or hallways - 50 ml/m² undiluted after deep clean
- Outdoor slate patios exposed to UV and frost - 70 ml/m² undiluted after outdoor cleaning
- Faded slate fireplace surrounds - 40 ml/m² undiluted for colour pop
- Restoring antiqued slate worktops after sanding - 60 ml/m² undiluted
How to Apply
- Shake the can, pour Slate-Oil into a paint tray, and load a lint-free cloth.
- Wipe a thin, even film across 2 m² sections; keep wet edges to avoid lap marks.
- After 10 minutes, buff off excess oil with a clean cloth until the surface feels dry.
- Let the area sit 2-4 hours before light traffic; avoid moisture for 24 hours.
Covers 15-30 m² per litre depending on slate texture. Full cure 24 hours at 20 °C.
Surface Compatibility
Excellent on slate because its Mohs 4 matrix is acid-resistant and mildly porous, letting the neutral oil lodge without etching. Do not use on polished marble, glazed ceramic, or any surface where darkening is unwanted.
Choosing the Right Product
For routine washing, use MN Wash & Clean. For stripping old waxes before re-oiling, reach for MN Power-Clean.
Pro Tips
- Warm the room to 18-22 °C; higher viscosity at low temperatures reduces penetration.
- Test absorbency by placing a drop of water; if it darkens immediately, Slate-Oil will bond uniformly.
- Re-buff after 30 minutes to remove weeping spots; prevents sticky patches that trap dust.

Frequently asked questions
How often should Slate-Oil be reapplied?
Every 1–3 years or when water no longer beads; high-traffic kitchens may need annual refresh.
Can Slate-Oil stop my slate floor from flaking?
It will not prevent natural delamination, but sealing pores with 50–70 ml/m² reduces moisture that accelerates flake formation.
Difference between Slate-Oil and MN Colour Intensifier?
Slate-Oil is oil-based and slate-specific; MN Colour Intensifier is solvent-based, universal, and adds stronger stain resistance.
Is Slate-Oil food-safe for countertops?
Yes, after 24 h cure the cured film is inert and meets EN 1186 migration limits.
