Natural oil-based protective decking oil that does not peel, crack, flake or blister. Penetrates the surface and bonds with the wood fibers to produce a durable water repellent surface. Osmo Decking Oil slowly weathers away in time and is simply recoated every once the finish becomes weathered.

  • Microporous, breathable finish that allows the wood to breathe and reduces the risk of swelling and shrinkage. 
  • Highly water repellent
  • Extremely weather and UV resistant
  • Easy to apply and renew, with no sanding or primer necessary
  • When dry, the finish is safe for humans, animals and plants and is suitable for children’s toys as per EN 71.3 (European norm) and DIN 53160 (German industrial norm).

Tip: The type and age of timber can have a dramatic impact on how much Decking-Oil you need.

As an example, softwood decking that is old will likely require more oil than a relatively new hardwood decking that still retains a fair amount of natural oil.

To test how much oil your decking needs, apply one thin coat, allow to dry, then apply a droplet of oil in a corner. If the droplet of oil soaks into the wood then a further coat can be applied. Repeat this process until the droplet of oil sits as a bead on the surface of the wood and no longer soaks in to the timber. This is an indication that the timber has absorbed as much oil as possible and doesn’t require any more.
