Drying oil for treating and polishing joinery in all types of wood
Available in 5 litre and 1 litre containers. Retailers
FURNITURE OIL is extracted from linseed oil using our unique refining process, consisting of 100% unsaturated (i.e., drying) linseed-oil fatty acids made non-biodegradable by pre-polymerisation, giving the oil the desired viscosity and drying time. FURNITURE OIL dries into the polymer linoxyn (which permanently attaches to wood and resists microbes, insects, fats, petroleum products, salts and acids regularly found in the household, e.g. lemon, wine and vinegar). At 20°C / 60°F and with good ventilation, FURNITURE OIL dries in 24 hours or less. Read more on this here: TECHNOLOGY.
FURNITURE OIL and LINSEED VARNISH OIL create beautiful and durable wood surfaces, from matte to high gloss.
Note that birch and beechwood becomes mottled when oiled and thus a good oiled surface is difficult to achieve. This is because these woods absorb lots of oil, and the colour of the wood varies, particularly on different grains of the lamellas.
First impregnate the wood with warm FURNITURE OIL.
Then create the desired surface - from silk matte to high gloss - the following day by oil-polishing, using a coarser or finer polishing cloth. (Polishing with LINSEED VARNISH OIL produces an even harder and shinier surface.) FURNITURE OIL is free from solvents, and therefore will not cause the wood fibres to rise on the surface - i.e., no extra sanding necessary.
FURNITURE OIL is absorbed 1.5-3 mm (roughly 1.5-3 250 of 1”) into the wooden floor, and produces a deep lustre that cannot be achieved using waxes or synthetic oils, which do not penetrate the surface. Damage to the surface is easily fixed by grinding off the damaged wood and then oil-polishing that area.

Sand the floor with an abrasive pad, #180 or finer - a coarser sheet creates marks that the oil cannot fill when absorbed by the wood.
Heat the FURNITURE OIL to 130°C / 266°F in a deep-frier.
Apply a liberal amount of FURNITURE OIL using a natural-bristle brush. Spread from saturated areas to areas still absorbing oil. Apply and spread until the entire area is saturated and a thin layer of oil remains on the surface. When treating wood at 130°C / 266°F with FURNITURE OIL, moisture in the wood evaporates, bordered pits open outwards due to the vapour pressure in the cells, and the warm FURNITURE OIL penetrates. Little steam bubbles on the oil surface are sometimes visible when applying warm FURNITURE OIL.
You can safely work with 130°C / 266°F FURNITURE OIL - it will neither burn nor fume. It’s poorly heat-conducting, so you can dip your fingertips in it or wipe your brush against your hand with no risk of burns. Its boiling point is 300°C / 572°F, and it will start to exude a white, sharply smelling steam from its surface at 180°C / 356°F. At 130°C / 266°F, it will only produce a faint smell of linseed oil.
Give the oil time to be absorbed - for half an hour to one and a half hours.
Sand in the oil using a #240-320 abrasive sheet on a single disc scrubbing machine. The resulting oil-saturated dust fills the roughness of the wood surface and produces an even and smooth surface.
Remove all remaining oil and dust left on the surface after 20-30 minutes. Oil left on the surface will leave a sticky skin. If that happens, gently use a card scraper to remove the skin and then machine-polish with FURNITURE OIL.
Give time to oxidate: the oil dries by oxidation and the time needed for drying is dependent on two factors: the supply of oxygen and the temperature. The oil can dry to the touch in a few hours’ time on a windy, hot summer day, whereas it can take up to a week in a cool, poorly ventilated garage.
Polish to the desired gloss - from matte to high gloss - using an abrasive sheet or polishing pad and some FURNITURE OIL, or Selder & Co’s LINSEED VARNISH OIL for a higher gloss. Use a #3000-#5000 polishing pad for a high-gloss surface, a #1000-#2000 for semi-gloss, a #220 abrasive pad for a silk-matte surface, or a #100 abrasive pad for a coarser surface. Keep the surface moist by wetting the abrasive sheet or pad with FURNITURE OIL or LINSEED VARNISH OIL. Repeat until the entire surface has an even sheen.
Wash brushes and tools used with strong soft soap, e.g. STRONG SOFT SOAP.
No respiratory protection necessary. Provide good ventilation. The oil is a poor heat conductor and does not cause burns if spilled, but be aware that metal objects that have been in warm oil burns.
WARNING: DANGER OF SPONTANEOUS COMBUSTION!
Cloths and other porous materials moistened with linseed oil must be soaked in water before disposal. Oil-treated surfaces do not ignite on their own. The danger concerns only fibrous materials.
Warning: do NOT clean the surface with alkaline detergents (like STRONG SOFT SOAP), as the oil reacts with basics and the outer layer dissolves, and the surface has to re-polished.
Any damages to the wood can easily be fixed by sanding off the damaged wood and then oil-polishing that area.
