Find out more about how to protect your decking from the effects of weather and sunshine in our blog.

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. For best protection treat decking with Barrettine Premier Wood Preservative or other exterior wood preservative first
  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 applying a decking treatment.

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, sanding or using a dedicated decking stripper and remover. This may require more than one attempt.
  2. Old oil finishes should be cleaned thoroughly with Barrettine Decking & Patio Cleaner or other suitable decking cleaner
  3. For decking affected by mould, algae or moss, use a Barrettine Mould and Mildew Cleaner
  4. For the best protection, treat with a suitable wood preserver
  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 and final finish.

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 Barrettine 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.

Q. What's the difference between a coloured decking oil and a decking stain?

A. Coloured decking oils and decking stains both change the appearance of wooden decking by changing the natural colour of the decking boards. Most types of decking stain form a coloured coating over the top of the timber while decking oils penetrate in to the wood grain and stain the wood from within. In terms of maintenance, decking oils are easier to patch repair and maintain plus they will never crack, peel or flake.

Easy to work with, beautiful finish by Dr Maureen Pearce

Project: preserve and finish new drive gates made from Scandinavian Redwood - a softwood.This oil was recommended to me by Alison at Wood Finishes Direct for 2 coats after first treating with Barrettine Wood Preservative, one coat of which had already been applied by the gate suppliers. I have worked with Danish Oil on interior wood before and this was sort of similar but easier to apply with the recommended paintbrush. I didn't put it on too thickly and the gates have come up beautifully. As others have said, it doesn't form a coating on the wood but is absorbed and dries to a lovely sheen. The rain drops just sit on the surface until they are blown away or dry. Really pleased and thank you for the good advice Alison.

Really nice finish Enhances the wood finish by Sean

Great protection from the elements. Appearance of rain droplets on timber fencing demonstrates the protection it is giving to a newly erected timber palin structure. Lovely colour after one coat.

We have a massive decking area and this went on with a roller in no time at all, the colour was good just remember to shake the cans or the colour will not mix correctly.

Excellent by Patricia Bryant

Had some neglected decking which I cleaned, left to dry and then coated with the decking oil. This was easy to apply with a brush, soaked in well and dried quickly. A second coat was applied and any rain now just "beads" on the surface. Very pleased and would definitely use it again.

Easy to apply and produce a richly coloured finish. Seems pretty water-resistant. It will be interesting to see how it fares over winter.

First rate by Bill

This is a very thin clear oil. It soaks readily into untreated wood, and repels water as indicated. I suspect it would require regular re-coating, but is extremely easy to apply. The advice given on the website was both useful and accurate.

Pleasureable by Tony Miller

Easy to apply, true red cedar colour matches the red cedar paint applied to the decking spindles. Only needed to apply one coat, but will apply a second coat just in case. I found brushing it on very easy with a wallpaper brush.

Excellent product on Decking! by Carole M Simonsen

I had builder fitting external wall insulation last year and left my decking in a mess. I had previously treated it with Ronseal decking stain which was a paint that I had to reapply every year as it would wear off in areas. I decided that I would have to use a different product that was easier to apply and would last longer. I researched online and as I had used the Barrettine Log Cabin treatment I purchased from Wood finishes which was great decided to try the decking oil. I used a pressure washer on the decking first but there was still a lot of patches left so I had to spend many days with a mini wire brush, small chisel and nitro morse to remove the paint. I then jet washed the decking again and with a hard scrubbing brush applied 2 cups of Oxi bleach powder to a bucket of hot water and scrubbed the decking, left it for a couple of hours ( can be left on for 1/2 hour +) there is also a yacht decking cleaner I bought online (it is a pink liquid) that I used to remove cement splash stains on my pine log cabin that you can use on stubborn marks then I hosed off the solution and left it to dry. I applied two coats of the clear decking oil and was amazed at how my 14 year old decking looked as new! I have just finished replying another two coat this year and it still looks outstanding and this oil has even has given my wood table and chairs a new lease of life!
