A drying oil which makes wood water-repellent, rot resistant, dimensionally stable and increases its bending strength. Contains no solvents.
Available in 0,25, 1 and 5 litre tin canisters, 200 litre drums, 1000 litre IBC containers. Where to buy.
PRIMER OIL is linseed oil from which the non-drying ingredients have been removed with our unique refining method. It penetrates the substrate and dries quickly by a reaction with the oxygen in the air to linoxyn, a natural polymer with excellent adhesion. It is non-biodegradable, water-repellent and resistant to fats, petroleum products, salts and household acids, e.g. lemon, wine and vinegar.
At 20 °C / 60 °F and with good ventilation, PRIMER OIL dries in 24 hours or less.

PRIMER OIL makes wood rot resistant by making it waterproof - fungi cannot grow in dry wood, and no organism can extract nourishment from the oil.
Field tests and tests in a rotting chamber show that wood deep impregnated with PRIMER OIL remains free of rot for a minimum of 24 years - in moist soil!
Sample of sapwood of pine deep impregnated with PRIMER OIL, which was in soil and in the soil band for 23 years, from 1994 to 2017 in the test field in Simlångsdalen, Sweden, of the Swedish University of Agricultural Sciences. Read more under SELDER WOOD.
The dimensional stability and the increased bending strength - doubled in our experiments - is a result of the wood forming a natural composite with linoxyn.
Sunlight will make the surface turn grey. The original colour of the wood can easily be restored by rubbing a small quantity of PRIMER OIL into the surface.
Wood can be protected with PRIMER OIL in several ways. The simplest method gives surface protection, with more advanced methods the oil penetrates deeper into the wood.
