Linseed oil paints as an ideal wood preservative

colours based on linseed oil have demonstrated their positive characteristics and have been in use over centuries. Linseed oil paints are permeable and thus prevent the wood under the paint from rotting unnoticed under the paint’s surface. Most linseed oil colours are weatherproof. Linseed oil has a small molecular size, so it penetrates easily deep into the surface on which it is applied to. In comparison to other types of colours, linseed oil allows the best possible adhesion. Linseed oil increases its mass density after it has been applied and therefore does not allow water to penetrate the wood’s surface. The wood is protected and does not rot. In addition, the paint’s own pigmentation provides protection against the ultra-violet radiation of the sun.

Linseed oil paint preserves and protects the wood

Treating one’s windows and doors with linseed oil paints guarantees the best optimal care. Linseed oil also characteristically known for its elastic coating. On organic surfaces, linseed oil proves itself to be a big advantage. Wood adapts to the climatic changes in the environment. It shrinks or expands in accordance to the humidity conditions. In comparison to other plastic based paints, linseed oil can adapt to these changes largely without flaking or tearing, reaching an optimal isolation even between colour layers.

Paints based on linseed oil are easy to maintain. After about 5 years of exposure to weather conditions, it is advisable to refresh the painted surface by simply using a cloth with linseed oil and applying it to the surface where withering is visible. To do sweeps either a thin layer of linseed

oil on the surface of withering or rub it with a linseed oil soaked cloth. The surface appears fresh and is again protected for years to come.

Linseed oil colours are available in every colour, every shade conceivable. Either modern or historical.

Protect linseed oil colours protect and preserve wood best. It has been scientifically proven. In a Danish test trial, initiated by the local Danish painter Association, windows of a historically listed building, which were originally treated with commercial wood colours / wood preservatives, were then treated with (acrylic / alcohol based paints), including linseed oil colours. After 10 years (2012), the experiment was analyzed and showed both significant as well as convincing results. The windows painted with linseed oil paints had shown none to minimal defects. The colour surface and the underlying wood was in very good condition. Acrylic and alkyd paints, on the other hand, illustrated disappointing results. Even after a short time, brownish rust blemishes enveloped the window fittings and even the paint had begun to peel.

Linseed oil paint for metal

Linseed oil colours, by the way, are also an ideal metal coating. A thin layer of linseed oil paint mixed with Zink or Iron provides an ideal sacrificial layer and thus the best rust protection. The paint prevents the ingress or penetration of water. After the sacrificial layer has been applied, the metal surface itself may be painted with every imaginable hue. This way it can be adapted to fit any individual need.


Pure linseed oil colours are made of linseed oil and a paste of in oil grated pigments. To speed up the drying oil paints, one adds desiccants. Therefore linseed oil colours are almost entirely from natural raw materials and, above all, from a few and known ingredients. Pure linseed oil colours are free of resins and solvents.
