Use Osmo Power-Gel

Apply a generous amount of Osmo Power-Gel with a brush and let it soak in for about 20 minutes. Then scrub the wood clean with a brush and rinse thoroughly with water. Use a dry cloth to remove excess moisture and let the wood dry completely before proceeding.

Treat standing and lying wood parts

Vertical and horizontal wood elements have different protection needs:

  • Relative elements (such as a hardwood fence): Use Osmo UV Protection Oil. This oil protects against UV radiation and prevents the wood from discolouring and greying due to the sun.
  • Lowland elements (such as decking): Use Osmo Decking Oil, specially designed to keep out moisture and prevent wear on the wood caused by use.

Apply a second coat

After a drying time of at least 12 hours, apply a second thin layer of the appropriate product. Use UV protection oil for vertical surfaces and the Terrace Oil for horizontal surfaces. This second layer provides optimal protection against precipitation, sun, and other weather influences.
