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.

Lindsey Gibson

Great product, great service!
After pressure washing my decking this is the first time I have oiled it (in 5years!) and it now looks like new. Had to wait a few weeks between coats (due to weather) but can really notice the difference when the second coat had been applied. Water now sits in beads on the surface and doesn't penetrate the wood. Can't stop admiring it each time I look out the window. Can't rate this product or the service highly enough.

I used this on my decking after 1 coat of Barrettine Wood Preserver. Very easy to apply and gave a nice, rich-looking finish. Very pleased.
David Nicholson

Easy to use does splash a bit if using a roller.
Goes a long way and seams to be protective. Used this on a shed in side and out.

Swift delivery, excellent product, easy to use.
Very pleased, oil goes right into wood unlike the previous product I used which left a sticky surface which gathered dust and dirt (I live on an unsurfaced lane!)Has just rained overnight and it's good to see the water laying on the surface and not soaking the wood.

Does what it says on the TIN
Absolutely brilliant!!!!!!

Good quality oil, strong water resistance and quick delivery
The oil soaked up the wood more than expected but possibly because the wood has had a number of treatments to it over previous years. With just one coat the water balanced on top nicely so after 2 coats I believe that should hold out for a good year before re coating. The colour of stain I used was light oak colour but it has produced a deep orange type colour so that would be the reason for only 4 stars. Overall good water resistant oil that leaves me confident of a strong protection against external weathering

Excellent Product
Goes on easily, seems water repellant, only been down a few weeks so early days. Like the colour matches our Irish Oak canopy cladding well. Coated the tops of the joists as well and water beads off.

Everything Barrettine is always excellent, this is no exception

Very pleased with this so far
Easy to apply, looks great, good value. Does not smell that much despite what some people have said. After being on for a couple of weeks it seems to be doing the job. I'll definitely be using it again if it continues to live up to it's early promise.
John Gregory

Excellent service, quality product
Service was very prompt. The product itself is extremely effective. Rain bubbles on the surface. It is easy to apply and adds a depth of natural colour and brings the grain out in the wood.

Best oil i have used
Forget Ronseal, this is the bee's knees. Two coats on my new decking and it looks lovely. Rain-water just beads off. Best product you can buy, ps I used the clear and it does not change the colour of the wood.

Looked good on reviews
Used Ronseal on our decking last few years and it always peels! put 2 coats off Barrttine decking oil on and went on easily and looks pretty good! will review again after winter and see if its as good as it looks!
Van Patel

Really good Quality Clear Oil
This has to be the best quality Oil i have found. Includes UV filters and a slight tint after application, but really looks and feels good. The Oil does spread very well indeed without leaving any sticky residue. Used a 1.5" good quality paint brush for the bannisters and smaller areas starting from the bottom working my way up to minimise drips and runs and for the floor area used Manns decking pad Only issue was that the tin could have had a protruding spout which would have helped greatly in pouring the liquid into other containers...but other than that goes on very well Bought 6 tins at the reduced price to give 2 x costs on an approx deck inc bannisters of 60sq meters...Soaks in very well indeed and I used approx 3.5 tins on the first coat so the second shouldnt take too much... Will always buy this product as long as the price is right....
