Holzol Decking Oil is formulated from a blend of natural oils modified with urethane resin and is suitable for most types of garden wood including soft and hardwood decking, garden furniture, sheds, fences and more.

Decked areas to be treated should be clean, dry and free from traces of oil, grease, wax and silicone.

New or untreated decking

New hardwood decking may require a period of weathering to open up the grain, making it easier for the oil to penetrate in to the surface of the timber. The time is dependent on the wood type and weather conditions but is usually 6 to 12 weeks. New and untreated softwood decking can be oiled immediately.

  1. Decking should be swept with a stiff broom to remove all surface dirt and debris
  2. Traces of mould and algae should be treated with a suitable decking cleaner
  3. To restore the colour of grey or silver decking, first use a decking restorer if required
  4. Treat decking with a decking preservative to protect against mould, algae and insect attack

Previously Treated Decking

Old coating systems such as decking paints and varnish like decking stains must be fully removed back to bare wood before oiling.

  1. Remove old decking finishes by pressure washing or using a dedicated decking stripper & remover
  2. For stubborn areas, allow decking to weather for several weeks then repeat process
  3. Old oiled finishes should be cleaned thoroughly with a suitable decking cleaner

Please note: Decking that has been oiled within the last year may not be ready to absorb a new coat of decking oil. It is advisable to treat a small test area first to test absorption. If the oil on the test area fails to penetrate, dry in the specified time, goes tacky, sticky or forms a film on the surface that can be easily scratched off then delay oiling.

Always do a test area before starting any project to check suitability and compatibility. Follow the manufacturer's instructions on the tin at all times.

  1. Stir the tin thoroughly before and periodically during application
  2. Apply a thin, even film of deck oil with a suitable decking applicator
  3. Work the oil in to the surface of the wood grain
  4. Wipe off any excess oil with a clean lint free cloth
  5. Allow the first coat to dry for 8-12 hours
  6. Apply a second coat as above.
  7. Allow 24 hours to completely dry
  8. If the decking is particularly dry, a third thin coat can be applied if necessary

For decking steps and other high traffic areas that require slip resistance, one thin coat of Osmo Anti Slip Decking Oil (430) can be applied over one coat of Holzol Decking Oil.

To prolong the life of the decking finish and timbers, it is recommended that decked areas should be dry swept with a stiff broom to remove surface debris such as dirt, plant and insect matter from the grooves regularly. This is especially important for decking surrounded by trees and plants that shed their leaves and for decking located in damp or shaded area.

  1. Sweep on a regular basis, more so in the winter months
  2. Clean with a suitable decking cleaner to prevent and remove traces of mould and algae


High foot traffic areas that start to appear worn or tired looking, or that are losing the ability to repel water effectively can be easily restored. First clean with a suitable decking cleaner then re-apply a thin coat of Holzol Decking Oil to the affected area for an invisible repair.
