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.

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.

A1 up until now
The oil has not been on long enough to really test its longevity but all's well so far

Easy to apply and transformed decking
Several years since I last treated the decking so the coverage was high at around 3 sq.mtrs per litre. However, it was worth it to see the transformation in my 15 year old decking. I used clear oil over a Golden Brown preservative. Will probably redo it in a couple of years. If the finish lasts it will probably warrant 5 stars.

Brilliant - outdoes other well known products
I have to say the Wood finishes Blog on Decking Maintenance was extremely helpful, I carried out their drip test recommendation to see if our deck required oil, so much so it was this factor that convinced me to use their services. I have used many well known Decking Stains and Oils in the past, so taking the Blog recommendation I ordered Barrettine Decking Oil and so glad I did. It was everything Wood Finishes said it wood be. it gave a very nice finish although our Decking is 6 years old it was a little patchy so we ordered the Dark Oak Decking Oil and gave it a second coat and it was just brilliant. It bought our decking up like new (well slight exaggeration). The decking looks the best it has ever been and I would have no hesitation in recommending Wood Finishes and this Barrettine Decking Oil.

Easy to use
Goes a long way, difficult to see what has been done, so have to keep a check on where you have got to.

Easy to apply, good coverage and gives a nice rich finish.
Applied after treatment with Osmo wood reviver on 8+ year old weathered decking. Surprisingly good coverage, soaked into the wood well but didn't just disappear like I've experienced with cheaper oils. Had enough for 2 coats which I would really recommend as the 2nd coat really brought the wood to life, the 1st gave a deep rich colour but left the knots a bit white. The 2nd coat darkened everything down and now it looks very similar in colour and look to oak (which has gone down very well with the 'boss'!)very surprised at that. It's gone from looking a bit tired to looking nicely worn in now. First bit of rain showed the beading qualities of the oil, which hopefully also shows it's protective properties. Would certainly recommend.

Delivered on time - job done !!
Decking had not been treated previously and had been down 7 years or so - lots of moss and dirt and had gone silver in colour. Power washed the decking which got rid of the dirt, moss and got it back to it's original colour. Left to dry for a week or so, then applied 2 coats of the Barrattine Oil. Worth getting the Osmo floor brush apply it - saved a lot of time. The coverage is pretty much as stated and the clear oil sinks well into the wood and leaves a great natural look, not at all 'orangey' like some other brands. Time will tell how long it'll be before I need to recoat again.

Great product
The oil completely transformed the look of my decking and was very easy to apply. Cannot comment on the longevity as I have only had the decking for a month but I expect it to last a few years given the brand and based on other reviews. Delivery was very quick and overall, it does the job perfectly

Very Happy With Product And Service
We put this decking oil down about 2 months ago now and it looks good and works well. Very easy to apply with the Manns Decking brush. We had quite a large area to cover( three decks!) but it was done and dry within a few hours. Highly recommend.
