Barrettine Decking Oil Overview

Barrettine's decking treatment enhances the wood grain and revitalises decking. It contains high quality agents to prevent splitting, algae and mould. Once dry on the wood it is safe for humans, animals and plants.

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...


If your decking is not preserved we recommended that you treat with Barrettine Wood Preservative prior to oiling.

Before application it is important to ensure that your deck is free from any pre-existing algae and mildew. For best results, jet wash and apply a decking cleaner before applying the decking oil.


Apply 2 coats with a view to re-oiling the decking at least once a year.


Brushes and roller can be cleaned with white spirit after use.

Drying Time

Drying times are generally between 12 and 48 hours depending on the type and condition of decking, application of the decking oil and environmental conditions.

Will always use this in future
Have used various decking products/stains/oils over recent years and this is by far the best - will always use this in future. Also get the useful applicator - it made the job so easy.

Great product
I used this product on some old railway sleepers that were looking worse for wear. Firstly they were power washed and then I applied 2 coats of the dark brown Barrettine Premier wood preserve and then one coat of the decking oil. They look smashing. This product was very pleasant and easy to work with and I am delighted with the result.

Excellent absorption and good colour
The decking 'drank' this oil up, so needed more than initially thought, however was very pleased with the look and feel of the decking after, it went on very easily with a soft floor brush

Better than what it says on the tin
delivered promptly, 2 coats and it looks splendid (certainly better than some of the so-called big name rival products I've used in the past!)....now, can we have some fine weather now so we can enjoy the decking?

Easy to use. Does not change the decking colour.
Excellent fast service. Oil does a great job. Water beads up and can be brushed off easily. You feel that the wood has been protected.

Great product.
Easy to use and does a great job. Water just runs off decking. Clear decking oil dries to leave wood slightly darker. Wood actually looks better.
