Drying oil for treating and polishing parquet and wood floors
Available in 5 litre and 1 litre containers. Retailers
FLOOR 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. FLOOR 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, FLOOR OIL dries in 24 hours or less. Read more on this here: TECHNOLOGY.
FLOOR 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. Therefore the treatment is permanent until the impregnated wood layer has been worn down, which usually takes decades. Damage to the surface is easily fixed by grinding off the damaged wood and then oil-polishing that area.
Shiny streaks may appear on floors after years of wear. These can easily be revived by polishing with a cloth or pad and a small amount of oil.

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..
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 FLOOR OIL to 130°C / 266°F in a deep-frier.
Apply a good amount of FLOOR 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 FLOOR OIL, moisture in the wood evaporates, bordered pits open outwards due to the vapour pressure in the cells, and the warm FLOOR OIL penetrates. You can see small steam bubbles on the surface when you apply warm FLOOR OIL.You can safely work with 130°C / 266°F FLOOR 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.
Let the oil 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 makes it even and smooth.
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 FLOOR OIL.
Give time to oxidate: the oil dries by oxidation and the time needed to dry 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 sheen - from matte to high gloss - using a single-disc scrubbing machine and an abrasive sheet or polishing pad and some oil. A #220 abrasive pad produces a silk-matte result whereas a #1000-#5000 polishing pad will produce a semi- to high gloss result #100 coarseness slip protection. Keep the surface moist by wetting the abrasive sheet or polishing pad with FLOOR OIL. Repeat until the entire surface has an even sheen.
Note: do NOT polish too large surfaces at a time if you use Selder & Co’s LINSEED VARNISH OIL. With a floor at room temperature or warmer, the oil will dry before you’re finished working.
Wash brushes and tools used with a 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 contact with 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.
