Pure Swedish Boiled Linseed Oil

Swedish cold-pressed boiled linseed oil is of the highest quality. The oil is stored for at least 6 months after being pressed so that any slime products may settle. The oil is then heated to 140⁰C for seven days. It is a natural treatment without any chemical additives. The absolutely pure linseed oil is then decanted to another storage tank.

Linseed oil has a lower surface tension than water and therefore penetrates deeper than water into all forms of substrate. This ability renders it unrivalled where protection against wood rot is concerned. In addition to oiling, boiled linseed oil is used to dilute linseed oil paint outdoors. Boiled linseed oil dries substantially more quickly compared to raw linseed oil.

Applications: Use this organic boiled linseed oil as a base coat before linseed oil paint. Wood Shingles, Wood Siding, Wood Decks, Porches, Wooden Boats, undercoating for cars etc.

Paint Removing: Use to reconstitute old paint prior to heating with the Speedheater paint removal system. Softens paint layers and reduces paint dust created by scraping.

This product is not bleached or filtered. Not for food or hygiene applications. Not sensitive to freezing. Organic Raw linseed oil dries significantly slower than organic boiled linseed oil.

About Linseed Oil
MADE IN SWEDEN The Scandanavian people have known about the unique properties of linseed oil for several thousand years. Linseed oil penetrates into wood, protecting it from moisture and rot.

Linseed oil is cold pressed from the seeds of the flax flower. This is done "cold" to prevent impurities getting into the oil.

The raw linseed oil is purified and refined through the addition of oxygen to produce boiled or "cooked" linseed oil. This process eliminates protein and improves aspects such as the drying time, shine and purity. Purified linseed oil is mold and mildew-free.

Questions & Answers

Have a Question?

Ask a Question
  • Is your boiled linseed oil highly combustible? What are your recommendations for storage in a hot climate?

    When used or stored improperly there is a slight chance of combustibility although that is almost exclusively linked to rags soaked with linseed oil not properly disposed of, not the linseed oil itself. Storage wise we recommend keeping it sealed and stored between 50-70 degrees fahrenheit avoiding exposure to light. Excessive heat can cause the linseed oil to deterioriate and become rancid. Humidity is also a factor you'll want to keep in mind as high humidity levels can cause the linseed oil to oxidize faster leading to a shorter shelf life or introduce bacteria and mold compromising the quality of the oil.

  • Does this have an indefinite shelf life?

    Yes! Our pure Swedish linseed oil will never expire. We recommend storing with the cap closed to prevent oxygen from getting into the container.

  • Swedish cold-pressed boiled linseed oil Is this product food safe? In other words, does it contain any additional chemicals?

    The Swedish cold-pressed boiled linseed oil does not contain any additives or chemicals. It is completely pure and natural!
