Solvent-free hard oil

KREIDEZEIT Hartöl -lösemittelfrei- (solvent-free) is a plant-based wood oil for interior use that is suitable for almost any application, providing hard-wearing protection for floors, worktops, tables, furniture and cladding.

It contains neither solvents nor water and consists exclusively of oils and resins of natural origin. For very dense, poorly absorbent or tannin-rich woods, slight thinning with gum turpentine is recommended. Can be tinted with KREIDEZEIT earth and mineral pigments.

Suitable substrates

Untreated or previously oiled wood in the stated area of application. Not on varnished or foil-laminated surfaces. A test area is recommended.

Use & Application

Preparation: Clean the wood and remove dust; initial sanding with P 80–120 grit (no finer, otherwise the wood will absorb too little oil). Shake the container before use and apply undiluted (for dense or tannin-rich woods, dilute the 1st coat with approx. 10 % balsamic turpentine oil).

1st coat: Apply thinly and evenly, leave to soak in for 10–20 minutes, then remove all oil that has not been absorbed with a lint-free cloth until the surface has an even silk-matt finish.

Intermediate sanding: Only if the surface has dried rough (grit P 100–120 in the direction of the grain), then remove the dust.

2nd coat: As for the first coat.

Tools & cleaning: Varnish brushes, wide wall brushes, cotton cloths, short-pile rollers. Clean tools immediately with gum turpentine, then with Oliven Pflegeseife or Korfu Seife.

Frequently asked questions

How do I apply oil correctly?
Apply thinly and evenly with a brush, cloth or short-pile roller, allow to soak in for 10–20 minutes, then remove all oil that has not been absorbed with a lint-free cloth. The oil must penetrate the wood completely and must not form a film.

How many coats do I need?
On untreated wood, generally two coats with drying time in between; sand lightly between coats if necessary. For woods rich in tannins (e.g. oak), dilute the first coat with approx. 10 % balsam turpentine oil.

Can I tint the oil?
Yes, with KREIDEZEIT earth and mineral pigments. First grind the pigments with a little oil until free of lumps, then stir them in. See the colour chart “Pigments in Oil”.

Why does the oil smell as it dries, and why does it yellow in dark areas?
When plant oils dry, a characteristic odour develops, which fades over time. In areas with little incident light, dark yellowing occurs – this is normal with linseed oil products.
