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.

Great Protection
Gives great protection and very easy to apply. I actually used on a fence after a coat of Barretine Wood preserver. I wanted the natural look and not the colour you get when you apply the fence paints. The clear decking oil gives it a very slight tint of colour, but actually the colour was really nice, still looks like natural wood colour just a tint richer/darker than when nothing is applied to the panel.

Very easy to use, dried quickly
Used product on top of Barrettine Premier wood preservative, produced a nice finish to the decking, applied with a firm brush on a long handle which was simple and fast.

Quick and easy to use, spreads evenly
Customers decking was in a sorry state, even had grass and young tree roots growing on it. After preparation of surfaces the Barrettine Decking oil applied in 3 coats gave a perfect even finish, customer was extremely pleased with the result.

Excellent product, easy to apply, deck looks great
I spent a long time deciding which product to buy to treat my one year old deck which is about 55 square metres and read a lot of reviews. I was most impressed with the reviews of the Barrettine Decking Oil and having now completed the job with two coats, I can confirm the result is excellent. I am delighted with the result the deck looks absolutely superb and well protected with the rain water beading on the surface. I shall be interested to see how long the treatment last, but on my experience so far I would definitely use again.

I've finally found a treatment that soaks into the decking!
I've been maintaining our decking for the last 6 years with a number of treatments all of which just coated the wood. At last I have got one that soaks into the wood and helps preserve it and will be doing the whole deck as soon as I can.

Leaves a really natural finish!!
This works just as you would expect from a classy product. The shed looks really natural still. Love it.

Ready for winter
Easy to decant, easy to apply and now rain beads and runs off the deck. The planks look smart and cared for. All indications are that this winter will be testing - the decking oil should do the job.
