INTERIOR WOOD FINISH · ART. 240
Hard oil for interior wood that soaks in — no film to scuff.
LEINOS 240 — EN 71-3 tested and biocide-free. Linseed, tung and castor oils harden inside the pore for high-wear Indian interiors: wood floors, cork, and unglazed terracotta.

Wood is a living material — actual colour depends on species, grain density, and substrate age. Each shade you see here is a reference. Our specialists confirm the final match with you before specification.
Beyond the Standard Range
Custom NCS or RAL tinting at our Delhi lab — any architectural reference matched across the full colour palette. Bring the spec, take the shade home.
Light, absorbent substrates can dry a touch darker, and each timber “fires up” differently by grain — a test-coat with colour match is essential. Colourless (002) adds water-repellency and depth without changing the tone.
Mechanism & Use
How LEINOS 240 hard oil works.
Penetrating oil-resin finish that hardens inside the wood — biocide-free and EN 71-3 tested for interior and children’s-room use.
01
Penetration
Linseed, tung and castor oils soak into the open pore. No surface film to scuff or peel.
02
Hard cure
Natural resin cross-links the cured oils into a hard-wearing matrix inside the fibre.
03
Breathability
Open-pore finish lets wood, cork and terracotta stay vapour-permeable.
04
Interior-safe
Biocide-free and EN 71-3 tested — clean enough for children’s-room furniture.
Where It Lives
Where 240 lives
Solid-wood floors & stairs
High-traffic floors, staircases and landings that need a hard-wearing, non-film finish.
Furniture, shelving & joinery
Tables, cabinets and built-ins that stay open-pore and spot-repairable.
Children’s-room furniture
EN 71-3 tested and biocide-free — cots, toy boxes and kids’ furniture.
Cork floors & wall tiles
Absorbent cork that needs water-repellency without sealing the surface.
Unglazed terracotta & clay tiles
Traditional Indian terracotta and clay floors — water-repellent, still breathing.
High-wear zones
Hallways, landings and worn-traffic areas where a film finish would scuff and peel.

Institutional Pledge
InVeNa Member
Reincke Naturfarben — full-ingredient-disclosure pledge for natural building products.
Unlike film finishes that scuff, chip and peel on high-traffic interior floors, 240 bonds inside the wood and renews with a single brush coat — no sanding, no stripping. Full maintenance protocol in the TDS.

How to Apply
Prepare the substrate — dry, solid, clean, grease- and dust-free, and absorbent. Pre-sand wood with 150–180 grit in the direction of the grain. Remove any old film coating (PU, lacquer, varnish) first — 240 needs an open, absorbent surface to penetrate.
Stir thoroughly and check conditions — stir 240 well before use (natural oils and pigments settle in storage); ready to use, do not thin. Keep room and surface temperature above 15 °C throughout application and drying.
Apply the first coat — brush, roll, spray or dip a thin, even coat into the absorbent surface. Let it soak into the open pore; the tone deepens as the oil penetrates. Coverage approx. 130–180 sq ft per litre per coat.
Second coat, wet-on-wet — apply the second coat wet-on-wet after a short 20–30 minute wait. At least two coats are required for hard-wearing interior surfaces.
Remove the excess — about 30 minutes after the final coat, wipe off all surface oil with a lint-free cloth, leaving a dry, open-pore satin finish. Any oil left on the surface stays tacky.
Dry, cure and care — dust-dry in approx. 10–12 h; walkable and recoatable after 16–24 h with good air circulation (a fan speeds drying and reduces odour). For extreme wear, finish with LEINOS Hard Oil Special 245. Store oil-soaked cloths in a sealed metal container or under water — spontaneous-combustion risk.
Coats & Recoating
- Apply at least 2 coats. Wet-on-wet application possible for second coat. Recoatable after 16-24 hours.
Cleaning & Storage
- Immediately after use, clean tools with LEINOS Thinner 200 or white spirit.
- Store in a dry and cool place, protect from freezing. Shelf life in closed packaging is at least 2 years.

Substrate Fit
240 works on — and what it doesn’t.
Suitable
Recommended substrates
- Solid softwood and hardwood
- Wood floors, stairs and furniture
- Cork floors and wall tiles
- Unglazed terracotta and clay tiles
- Absorbent engineered wood
- Children’s-room furniture (EN 71-3 tested)
Honest Limits
Where to use a different product
- Exterior wood, decks and garden furniture — use LEINOS 223 Teak Oil
- Painted, lacquered or PU-sealed surfaces — the substrate must be absorbent. Sand off any film coating first.
- Glazed or sealed tiles — 240 only penetrates unglazed, absorbent terracotta and clay.
Use With Care
Working safely with 240
- Oil-soaked rags and sanding dust are spontaneous combustion hazards.
- Store oil-soaked materials in a sealed metal container or under water until disposal.
- Store away from children.
- If swallowed: seek medical advice immediately; do not induce vomiting.
- Avoid release to the environment.
- Ensure adequate ventilation during drying.
- Wear approved respiratory protection (NIOSH P100 or CE equivalent) when spraying.
- Wear a particulate dust mask (P100 or CE FFP2 equivalent) when sanding.

Full Declaration
Composition
Every ingredient declared on the label. The Trust Hub explains what each one does and the standards behind it.
Linseed, Tung & Castor Oils
The penetrating body. Cold-pressed linseed (flax) is the LEINOS signature drying oil; tung-tree oil hardens the cure; castor (Ricinene) oil keeps the dried film slightly flexible so high-traffic floors resist micro-cracking. All plant-derived — they polymerise with oxygen and bond inside the wood grain.
Natural Resin (Rosin Ester)
Pine-derived natural resin ester. Cross-links the cured oils into a hard-wearing matrix inside the wood fibres — the “resin” in the brand’s oil-resin chemistry, and the “hard” in Hard Oil.
Isoaliphatic Carrier
Plant-derived isoparaffin solvent carrier (isoalkane, 40–50% by mass per Reincke SDS L-240; C10–C13, under 2% aromatics). Evaporates fully on cure, leaving the oil-resin matrix bonded in the wood.
Zinc / Manganese / Zirconium Driers
Trace metal siccatives (zinc, manganese and zirconium neodecanoate, 0.1–0.5% each per SDS L-240) that speed the oxidative polymerisation of the drying oils. No cobalt.
Mineral Pigments (tinted shades)
Earth and mineral pigments give the nine factory tones; the Colourless (002) base contains none. There is no IPBC and no biocide of any kind — 240 is biocide-free, since interior wood does not face the blue-stain fungi that attack exterior timber.

Frequently Asked
Quick answers on formulation, application and Indian-climate suitability. Pulled from our full FAQ and TDS library.
- Apply at least 2 coats. Wet-on-wet application possible for second coat. Recoatable after 16-24 hours.
- It depends on the existing finish. Synthetic coatings must be fully removed. Old natural oil finishes can often be recoated after light sanding.
- Allow full curing time as specified in the product TDS, typically 7-14 days for full hardness, though the surface may be touch-dry much sooner.
- Check the specific product TDS for food contact suitability. Many LEINOS interior wood oils are safe for food contact once fully cured.
- Both are LEINOS interior wood finishes, but the chemistry differs. 240 Hard Oil is a pure penetrating oil-resin — it soaks in and hardens inside the pore, works on absorbent surfaces including cork and unglazed terracotta, and is fully tintable in nine shades. 290 Interior Hardwax Oil adds a carnauba and beeswax micro-film on top for a slightly tougher, more water-beading surface on high-traffic hardwood floors and worktops. For cork, terracotta, or a tinted open-pore look, choose 240; for a wax-finished hardwood floor, choose 290.
- Yes. 240 is tested to EN 71-3 (migration of elements) and is biocide-free — there is no IPBC or sapstain fungicide, because interior wood does not face the blue-stain risk that exterior timber does. It is also saliva- and sweat-resistant per DIN 53160. Once fully cured and the surface oil wiped off, it leaves an open-pore finish suitable for cots, toy boxes, and children’s-room furniture.
