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.

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!

High quality proper decking oil - easy to apply by Mr D. M. Haigh

Had previously used Ronseal Ultimate Decking Stain, that although works really well when put down, does start to flake off where there is the most foot traffic after only 6 months. (Its only a house with 3 occupants!) Hard bit was removing the stain where it did not flake! (Believe me - this is no easy job. Many, many hours of sanding and scrubbing with wire brushes. (Did not use a chemical stripper after doing a lot of research.)) I expect this to be much better, as now the stain is absorbed into the wood, not just sat on the top.

First time I've used this product. Soaks well into wood and touch dry quite quickly. Very easy to apply making for even staining and even overall colour. Appears to be very good at repelling rain water - rain beads on surface. Easy clean up of brushes. Very pleased with finish.

Very simple to apply goes along way by Ron Elliott

This is the second time I have bought this product we purchased originally the light oak however we wanted the decking to be a little darker, but the dark oak was too dark, so we mixed equal amounts of light oak with equal amounts of dark oak and that gave us a perfect mid oak colour. Unfortunately Barrentine do not do a mid oak that we could find but it was so easy to mix. It is instantly waterproof and touch dry in about 2 hours it says on the can 24 hours between coats but I found about 4 hours between coats ample and it gives a brilliant finish ,I gave two coats to our deck one coat was sufficient but it was so easy to apply that it all got 2 coats and the transformation the second coat gave was brilliant. Its a great product I keep a spare 10Ltr mix in the garage for touch up and future projects like my pergola which is now completed and stained and looks awesome.
