Linseed oil has been used for centuries to protect and maintain interior and exterior wood. Thanks to its non-toxicity and environmentally friendly characteristics, it is undoubtedly one of the most popular finishing oils globally.

Impregnating the wood to saturation, linseed oil provides a golden hue, becoming amber over time. It deeply nourishes wood while providing flexible protection that is waterproof and abrasion-resistant.

Raw linseed oil has a drying time of about three days or more.

Key features of linseed oil:

  • Non-film forming (as opposed to varnishes)
  • Waterproof, elastic and wear-resistant finish
  • Satin finish
  • Slight smell of grass
  • Deep penetration
  • Golden to amber
  • Affordable and ecological
  • Easy to use
  • Easy care
  • Drying between 12 and 24 hours if polymerised and drying agents are used.
  • Enhances the beauty of the grain
  • Dried by evaporation and oxidation
  • Compatible with most oils

Want to do it yourself? Here is how to go about it:

  1. Sand the wood with 120-grit sanding paper to ensure good oil penetration.
  2. Mix the first coat with a mild citrus or odourless thinner solvent for better penetration.
  3. Apply the first coat with a brush, roller or cloth.
  4. 10 to 15 minutes after application, wipe the surface to remove any excess oil. Failure to complete this step will leave you with a sticky surface.
  5. 2-3 coats, applied at 12 to 24-hour intervals, are necessary for proper protection. Make sure you follow the directions specific to the product you’re using.
  6. For an ultra-soft touch finish, proceed with a light sanding with 600 or 800-grit sandpaper or fine steel wool at least 24 hours after the last application.
  7. Maintenance will have to be done about twice a year or according to the wear of the finish. Dry-looking or discoloured wood indicates that you must reapply a light oil coat. Clean the surface with a damp cloth, let dry completely and apply the oil, wiping off all excess oil after 5 minutes at most.

That’s the secret to a beautiful satin finish that will always retain its original appearance, given proper care.

Important: Getting rid of oil-soaked rags

A cloth soaked in linseed oil may catch fire! Dip the rags in water to prevent an exothermic reaction, and the danger is averted.
