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.

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.

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.

Easy application, looks great
Very happy with this product, my decking looks like new again. The only reason it does get 5 stars is that pouring from the can is awkward and ideally needs an extendable tube from the can as you get with car oil containers.

Most Satisfactory
I have given this product four stars as I have only recently finished treating my decking and is the first time I have used it. I applied two coats on top of one of Barrettine Premier Wood Preservative to Tanalised softwood decking over ten years old. Both treatments were quick and easy to apply with the finished result better than expected. Previous water based products by a famous brand had soon proved useless and short lived. I will definitely buy both these Barrettine products again and wholeheartedly recommend them.

As part of a 2-stage decking protection system; so far, I'm extremely satisfied
Put on one coat yesterday (over the previously applied Barrettine Wood Preservative) - it was simple and it looks good. It rained very heavily 12 hours later but as far as I can see (with lovely beads of water sitting on the surface) it has survived intact. My only adverse comments are (1) that the directions don't give guidance re. when to do it with respect to possible rain and (2) that the can I got has the 2nd-worst pouring characteristics I've ever experienced!

Will be ordering in spring for another coat on the decking
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.
Devon Customer

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.
Philip Gough

Very good finish and easy to apply
carrier must have dropped box(3 cans ) as very dented but did not leak.

Philip Butland

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
