Treatex Cedar Oil is designed for use on timbers such as Cedar and Larch. Great for unfinished surfaces such as cladding, doors, windows and exterior joinery. The oil penetrates deeply into the surface of the timber and attaches to the wood capillaries to provide protection against extreme climate conditions.

Manufactured on a base of sustainable raw materials which include sunflower oil, safflower oil and soybean oil, Treatex Cedar Oil is the perfect choice for you and the environment.

  • We strongly recommend that you try a test application prior to starting the project. 


  • Stir tin thoroughly before and during use.
  • Use a brush or roller to apply Treatex Cedar Oil thinly and evenly in the same direction as the wood grain.
