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.

Paul Buckle
Easy to apply
This is a very user friendly product. Went on easily; soaked into the wood to provide a smooth feeling finish.

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?
Noel Berry
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.

Easy to use
Bought this to go on over barrettine wood preserve . because of the consistency of the product it was really easy to apply .one 5 l can coated a 5m x 4m deck with balustrade and took only about 4 hours to complete .lovely finish and colour will definitely use again .excellent tracked delivery service too.
Michael O'Donnell
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.

Not been down long but my 15 year old decking looks great and the water is beading off it now. Was easy to apply and a great quality product for a good price.

 Dark Oak
Good quality finish
Good quality finish and easy to apply, but only time will tell about the surviving the weather
Michael Ward
Easy to apply leaving natural finish
This product soaks completely into the wood so that there is no flaking or cracking found with varnish type treatments. I made the mistake of using a decking varnish years ago and found it flaked off within a year or so. I am only just getting the finish I wanted origally by using barrettine as it has taken over 5 years to get rid of the old coating.

Easy to apply, sinks into wood well.
Easy to apply, sinks into wood, should protect well.
Paul McManus
Good product, good price
My deck was 6m X 3.5m most of it smooth side up I have given it 2 coats now and still have some left. Rain just sits on the wood now, it gave the deck a nice colour also.
S Sloper

Would recommend we even applied it to the wooden garden furniture last winter it did the work, thanks

Nicola Peirce
Great product.
I bought this product after reading the reviews. I used it for our new decking. It looks good, nice and easy to apply, repels water brilliantly. I would definitely recommend this product.

 Light Oak
so easy to apply, my decking looks great, rain just doesn't penetrate it.
Susan Williams
Please with this product on my decking.
I put two coats on my decking, it looked good, and now that it raining you can see its protecting the wood.
Marilyn Cox
Very impressed
Gave my new(ish) decking one coat of this, which was easy to apply. I used the clear version and it brought out the natural colour of the wood. I then finished with a coat of Osmo non-slip oil which does what it says on the tin. The decking beads nicely after rain so l would think the product is giving good protection against the elements.
