Flax is a renewable raw material grown in Sweden. The mature flaxseed is pressed without heating. The oil is then purified and filtered to obtain a sterile product free from impurities. Linseed oil has excellent penetrating properties in wood. Avoid solvents. Apply the oil to the wood surface. Use a heat gun or hairdryer to heat the oil into the wood, or heat the oil to 60 degrees Celsius and apply it to the surface. The oil must be well absorbed into the wood before painting over. Refer to the Little Handbook for further instructions. Available at your retailer and on the website.
