Decking oil is an essential product for keeping your garden decking in good condition, making it look good for longer and last longer too. Our blog post about decking maintenance reveals more.

Decked areas to be treated should be clean, dry and free from dirt, debris and other surface contaminates.

New Decking Preparation

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

New softwood decking

  1. Treat 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

New 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 decking should be left to weather before treating.

Old Decking Preparation

  1. Ensure that all 'coating' type finishes such as paints, varnishes and varnish like stains have been fully removed to expose bare wood by either jet washing or using a dedicated decking stripper and remover. This may require more than one attempt.
  2. Old oiled finishes should be cleaned thoroughly with a suitable decking cleaner
  3. For 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 a deck

Always do a test area before starting any project to check suitability and compatibility.

Do not apply Barrettine Decking Oil in wet conditions or if rain, frost or snow is likely before the product is dry. Decking area 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 wood grain
  4. Wipe off any excess oil with a clean lint free cloth
  5. Allow the first coat to dry for inline with environmental conditions
  6. Apply a second coat as above
  7. Allow 24 hours to dry completely before heavy use

Two coats of Barrettine Decking Oil are usually sufficient but this may vary depending on the type and condition of the timber to be treated.

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 decking boards and in the grooves, which can degrade or damage the finish and decking timbers over time.

If signs of mould or algae appear, use an appropriate decking cleaner. For general deck maintenance, 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 decking oil to restore the affected area.


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 Barrettine Decking Oil to the affected area for an invisible repair.

This is the best oil I've used by Diana White

I was going to use Ronseal but I came across this one, thought I would try it out. Would definitely use this one again, and on the plus side it was cheaper than the well known brands that the diy stores sell.

Visibly fed oil into the wood by Iskra Holstein

My decking has had several different coats over the ten or so years it has been down. However I never considered that wood can be oiled to preserve it. This product has made a huge difference. I will still have to keep removing some flaky deposits left by previous coatings but at least the wood is showing signs of deep protection, like beading rainwater. I just wish I had gone to the internet earlier and read reviews of products rather that reading off the back of tins available in local DIY...

Good quality, but colour is not what we expected by Fang Li

This light oak gave some colour, however, it doesn't come out nicely with the Wicks premium decking. We are happy with the quality but will not buy this colour next time.

Good quality, but colour is not what we expected by Fang Li

We thought we'd try this colour, but it turns out to be too red for our garden scheme and decking. Otherwise, the oil quality is good. We will be happy to buy it again but perhaps different colour option.
