Ronseal Decking Oil will leave softwood and hardwood decking protected and looking great for longer with a natural colour tinted or clear decking oil finish.

  • Have grooved decking? You'll normally need double the quantity. Our handy coverage calculator will help you choose the right amount
  • Looking for an anti-slip finish? Apply one coat of Ronseal Decking Oil then overcoat with one coat of Osmo Anti Slip Decking Oil

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

New Decking Preparation

For all bare wood decking including tantalised, pressure treated and preservative impregnated decking timbers.

New softwood decking

  1. Treat new softwood decking with a suitable exterior wood preservative for the best protection
  2. If possible, preserve all sides including end grain prior to installation
  3. Sweep the decking with a stiff broom to remove all traces of surface dirt and debris
  4. Use a suitable decking cleaner if required before oiling

New hardwood decking

Hardwood decking usually requires a period of weathering to allow the surface grain to open up. This allows for better absorption of the decking oil. Check the decking manufacturer's guidance on how long their wood deck should be left to weather before applying decking oil.

Old Decking Preparation

Old coating type finishes such as decking paints, varnishes and varnish type stains must be fully removed back to bare wood before oiling. Depending on the condition and type of finish, it may require more than one attempt to fully remove the old coating.

  1. Ensure that all 'coating' type finishes have been fully removed to expose bare wood by either jet washing or using a dedicated decking stripper and remover
  2. Old oiled finishes should be cleaned thoroughly with a suitable decking cleaner
  3. For garden decking affected by mould, algae or moss, or to restore the colour of decking that has turned grey or silver over time, use a decking restorer or reviver gel
  4. For the best protection, treat with a suitable exterior wood preservative
  5. If possible, preserve all sides including end grain prior to installation
  6. Sweep the decking with a stiff broom to remove all traces of surface dirt and debris before oiling

Always do a test area before starting any project to check suitability and compatibility. Do not apply Ronseal Decking Oil in wet conditions or if rain, frost or snow is likely before the product is dry. Decked areas should be completely dry before application. Follow the manufacturer's instructions on the tin at all times.

  1. Stir thoroughly before and periodically during application
  2. Apply a thin, even film of decking oil with a suitable decking applicator
  3. Work the oil in to the surface of the decking boards
  4. Wipe off any excess oil with a clean lint-free cloth
  5. Allow the first coat to dry in accordance with environmental conditions
  6. Apply a second coat as above
  7. Allow 24 hours to dry completely before heavy use

Two coats of Ronseal Decking Oil is usually sufficient but this may vary depending on the type of decking timber and its absorbency.

Regular Cleaning

To preserve the look and performance of the oiled finish for longer it is recommended that decked areas are swept with a stiff broom on a regular basis. This is to remove loose leaves, dirt and other organic matter that can settle on the wood deck and in the grooves, which can degrade or damage deck finishes and decking timbers over time.

If signs of mould or algae appear, use an appropriate decking cleaner. The condition of wooden decking should be inspected on a regular basis and treated as required.

Deep Cleaning

Scuff marks, stains, grease and other surface contaminates can normally be cleaned with a decking cleaner. Stubborn marks and stains may require a light sanding and a thin application of oil to restore.


High foot traffic areas that start to appear worn or tired, 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 Ronseal Decking Oil to the affected area for an invisible repair.

Used for many years Keeps our decking in good condition by Carolyn & Robert Chafer

Used for many years. Keeps our decking in good condition. Definitely seems to give better protection than the coloured decking "paints" as we have friends who use them and their decking has disintegrated.
