OLI NATURA® HS Professional Oil

What makes HS Professional Oil NATUR stand out?

HS Professional Oil has 100% solids content: It contains no solvent that evaporates during drying. The oil absorbed by the wood remains in its structure and cures there. When applied correctly, the wood can generally be saturated and protected with just one coat.

How much OLI NATURA® HS Professional Oil do I need for my surface?

Depending on the container size, OLI NATURA® HS Professional Oil covers the following areas with one coat :

• 100 ml: approx. 2.5–5 m²
• 250 ml: approx. 6–12.5 m²
• 1 liter: approx. 25–50 m²
• 2.5 liters: approx. 62.5–125 m²

Note: All coverage figures are estimates. Actual coverage depends on the type of wood, final sanding, the wood's absorbency, and the application method.

What does HS Professional Oil do to wood?

As an impregnating oil, HS Professional Oil penetrates the wood structure and cures there through oxidation. This makes it harder for water and dirt to penetrate. The wood structure remains visible; when protection wears off, the oiled surface can be refreshed.

Which surfaces is HS Professional Oil suitable for?

For untreated or freshly sanded wood and absorbent wood-based materials indoors, such as floors, stairs, furniture, tables, and countertops.

Which oil is right: HS Professional Oil NATUR or Colour HS Professional Oil?

NATUR is unpigmented and deepens the natural tone of the wood. COLOUR contains pigments, gives the wood a transparent tint, and leaves the grain visible. Test the color effect on wood prepared in the same way and assess it after drying.

Is a surface treated with HS Professional Oil waterproof?

No. Once fully cured, it is water-repellent but not waterproof. Wipe up liquids promptly and avoid standing water.

What condition must the wood be in before oiling?

It must be clean, dry, absorbent, and free of grease, wax, and other separating substances. Sand the wood evenly and remove dust thoroughly. The permissible wood moisture content is 8–12 %.

Can I apply HS Professional Oil to lacquered or previously oiled wood?

Completely remove old film-forming coatings so the oil can penetrate the wood. Check previously oiled surfaces for compatibility and adequate absorbency; if necessary, sand down to bare wood.

What final sanding grit is right for HS Professional Oil?

Do not sand floors and stairs finer than P100–120, or furniture surfaces finer than P180 . An even sanding finish is especially important for the color effect of COLOUR. Then remove dust thoroughly.

How is HS Professional Oil applied?

Apply the oil thinly and evenly, then work it into the woodwith a beige pad. After the soak-in time, remove excess oil and polish with a white pad until the surface feels dry to the touch. Do not leave any excess oil on the surface.

Can I apply HS Professional Oil by hand?

Yes. Smaller areas can be treated with hand pads. On larger areas, the oil can be worked in and polished mechanically; on floors, use a single-disc machine.

What is the advantage of HS Professional Oil's long open time?

The oil remains workable for longer after application. This makes it possible to oil larger sections of flooring evenly, rework absorbent areas as needed, and then polish carefully. This makes application more reliable and helps avoid visible lap marks.

Can I apply HS Professional Oil with hardener?

Yes. Thoroughly mix 10 parts oil with 1 part OLI NATURA® Hardener and apply immediately. The hardener speeds up curing and increases resistance; with COLOUR, it also improves pigment binding. The pot life is about 2–3 hoursfor NATUR, and about 1–2 hours.

What should I do if I have applied considerably too much oil and it is still wet?

If there is a lot of oil on the surface after the penetration time, remove the excess with a foam rubber squeegee before polishing. Then polish with a white pad until the surface feels dry to the touch and no excess oil is visible.

Why does the oiled surface remain sticky or dry only slowly?

There is often still too much oil on the surface. Low temperatures, high humidity and poor air circulation also delay drying. Polish off all excess oil completely. The materials, wood and surrounding area should be warm at +15 to +25 °C during application; ensure air circulation while drying.

When can I walk on an oiled floor again?

Without hardener, the surface can be walked on carefully after about 24 hours and is fully cured after about 5–7 days. With hardener, it cures faster. Protect it from water and heavy use until fully cured.

When can I clean the surface with a damp cloth?

Only after it has fully cured. After that, clean with a barely damp cloth using OLI NATURA® wood soap as needed.

When should the surface be refreshed?

When its protection starts to wear off, not on a fixed schedule. Clean the surface first and let it dry completely. For refreshing, use the care product specified in the relevant Technical Data Sheet. If you also want to renew the color on COLOUR, follow the separate application instructions in the data sheet.

Do I need to sand before re-oiling?

Not necessarily. When refreshing an intact, oiled surface, thorough cleaning is the first priority. Sanding may be necessary if there is damage, staining or bothersome residue from care products. The condition of the surface is what matters.

What should I keep in mind with oil-soaked cloths and pads?

They can spontaneously combust. After use, soak them completely in water and then spread them out to dry outdoors. Avoid heat buildup.
