Our OLI-NATURA boiled linseed oil is considered by many to be the most traditional and beautiful way to naturally protect wood indoors and outdoors. It is completely organic, vegan, free from harmful substances, and certified as food-safe. It is produced in a gentle boiling process using only cold-pressed linseed oil with a minimal amount of drying agent. Once cured, it forms a clear, water-repellent protective layer of Linoxin. Boiled linseed oil enhances the wood grain and the wood’s natural colour. Particularly light woods develop a pleasant honey tone.
Used undiluted and applied several times, it provides effective protection against severe environmental influences. However, you need to allow some time and be patient when applying several coats. The required drying time for the applied coat takes several hours with boiled linseed oil. Only afterward is it possible to proceed with the next steps.
Organic & Ecological
Linseed oil is obtained by cold-pressing the seeds of the flax plant (also known as linseed). This is very efficient in the case of flax, because linseeds consist of around 90% linseed oil. To prevent the oil from becoming rancid in the wood, it is purified, degummed, and finely filtered. To accelerate the curing process, the cold-pressed linseed oil is boiled and mixed with a siccative. This turns the linseed oil into boiled linseed oil. The siccative is a manganese drier of the latest generation, naturally free from lead salts and cobalt.
Food-safe
To guarantee its safety, our OLI-NATURA boiled linseed oil was tested and certified by an independent testing laboratory as food-safe in accordance with Regulation (EC) No. 1935/2004. Authenticity and migration tests were also included in the testing: Our OLI-NATURA boiled linseed oil was well below the permitted limit of 0.6 manganese mg/kg, with
< 0,01 manganese mg/kg. This means that our OLI-NATURA boiled linseed oil can be safely applied to wooden surfaces that come into contact with food: dining tables, worktops, cheese boards, bread boards, or knife blocks.
General rule
The absorbency of the wood depends on the type and condition of the wood, the user’s working method, and the sanding finish. As a general rule:
- Whatever the wood absorbs must be allowed to remain on it.
- Whatever the wood does not absorb must be removed while still wet.
At the same time, the protective effect must be refreshed regularly through occasional re-oiling. Surface scratches or damage on an oiled wood surface do not expose unprotected wood, because the oil protects the wood from within. Fine marks or scratches can therefore also be repaired easily: simply sand the affected areas and apply re-oiling. Any difference in colour will even out over time.
NOTE REGARDING THE RISK OF SPONTANEOUS COMBUSTION!
Special attention must be paid to oil-soaked rags and cloths, which can spontaneously combust due to heat accumulation. Naturally drying oils cure by absorbing oxygen from the air. This generates heat, which is normally released into the surrounding environment and is completely harmless. However, in oil-soaked and crumpled rags, cloths, pads, or sponges, the heat cannot escape, meaning that in unfavourable circumstances they can spontaneously combust. You should therefore never leave oily cloths or rags lying around carelessly; instead, soak them thoroughly with water, hang them up outdoors, and allow them to dry. Once treated this way, they can be disposed of safely after drying. Alternatively, oil-soaked rags and sponges can be stored under water or temporarily kept in an airtight, sealable container.
