Stone Oil

Drying oil that protects ceramics, brick, plaster, concrete and other porous stone materials against dirt and moist.

Available in 5 litre and 1 litre containers. Retailers

STONE OIL for stone materials 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. STONE 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, STONE OIL dries in 24 hours or less. Read more on this here: TECHNOLOGY.

STONE OIL:

  • is absorbed by porous stone materials assuring deep protection

  • replaces silicate treatments on non-sanded concrete with skin of cement

  • replaces epoxy treatments when sanded concrete is impregnated and polished

WORK MANUAL

Colour preview

The finished treated surface generally takes on the same colour as when it’s wet. Preview the tint by applying water on the surface.

Exceptions: white ceramics may sometimes become yellowish white, which will not be apparent when water has been applied. Before treating white or partially white ceramics, first try the result by applying STONE OIL on a tiny bit of the surface.

Impregnation

First remove any spots of dirt, as the treatment otherwise makes them permanent.
Floors in homes: liberally apply STONE OILwith a brush.
Public floors exposed to dirt: heat STONE OIL to 130⁰C / 266⁰F in a deep-frier. Liberally apply the oil using a natural-bristle brush.
Further applications for all floors: spread the oil from saturated areas to areas still absorbing oil. Apply and spread until the whole surface is saturated.

You can safely work with 130°C / 266°F STONE 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.

Remove all remaining oil left on the surface after 20-30 minutes (if the oil is cold: 1-2 hours). 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 STONE OIL.

Give time to oxidate for at least 24 hours. provide good heating and ventilation. 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 air-ventilated garage.

After-polish with a little STONE OIL, using a red pad on a smooth surface or a brown pad on a coarse surface. Keep the area moist by wetting the pad with STONE OIL. Polish until the entire surface has an even sheen,

Wash brushes and tools used with strong soft soap, e.g. STRONG SOFT SOAP.

WORKER SAFETY

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.
