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.

Ideal for my raised decking area.
After reading other reviews on this product, I went ahead and ordered two 5 litre tins of Light Oak decking oil. The product was delivered on time. Using the product was quite simple, and the finish gave the decking area a rich finish. Iwas a little worried about the "orange" effect that another reviewer had commented on, but this did not materialise. The second coat "recommended" gave the decking a deep rich finish. I have just ordered some more for our summerhouse.

On four 2 weeks so fare it seems good.
Put two layers on still kept the colour of the wood natural. Most clear oils still darken the wood.

This is a much better product than the more commercial decking oils you are able to purchase from the usual DIY stores.

First class product - deck protected for another year.
Although the tins were badly dented in the packing, delivery was very quick and efficient. An excellent product and is applied very easily.

Excellent product, easy application, excellent coverage, brings out natural beauty of the wood
. In terms of the barrettine clear oil- i used this first time after building my decking (i have a lot of wood to cover: appx 70sq metres) on recommendation of the guy at trade store. since then I've used ronseal and other main high street brands, never again. The oil is excellent, so east to apply (you need to use a brush) tried a pad option n it used too much oil and was very wasteful. Went on so easy and brought out fabulous colour to the wood. For anyone considering a decking oil this is the one to go for. I will only buy this product now.

Very good stuff well worth the money
Really good product I was looking for something that really was clear having been caught out before when tin said clear but actually had a colouring to it - this is just what I wanted as didnt want to change the colour of the decking at all - it is also easy to apply - I will definitely use it again

Excellent product for looking after the decking
Easy to apply, I gave the decking 2 coats and the finish looks great. Time will tell if it does what it says on the tin.
Shawn Tait

Simply the best product I have used
Very easy to apply with the sponge applicator. Applied twice and the decking looks like new! I will definitely be using this product again.
Antony Mead

Excellent product
The oil went on like a dream and it took comparatively very little time to give the deck several coats. The finish was only very slightly darker than the original but we liked it and would use this again
Diana Newnham

Brilliant product.
Thought I would try this oil out as my decking was looking rather shabby. Wasn't disappointed, after two coats rain just balanced on top, applied a third, decking looked a lot smarter. Delivery very quick.
John Harrison

Top decking oil!
Delighted with this decking oil. Went on a treat and really showed off the wood. Very easy to apply using the good (but expensive) Osmo brush I bought with it, and water beaded on the decking after the first coat. It took just 30 minutes to treat 25 sq metres I bought 2 x 5L cans, which will easily give me three coats. A great product at an unbeatable price from Wood Finishes Direct.
Peter Orpin

Superb product- easy to apply and works well
After a challenging experience with Osmo oil decking on my Siberian Larch decking that ended up growing a black mould I cleaned up the deck with powerwash and Barrettine Fungal wash and applied a single coat of the Barrettine Decking Oil. Works fantastically. Water just beads off it whereas with Osmo water was getting into the boards causing them to swell. Applied with the proper decking brush supplied by Wood finishes direct. I think having the right kit is really important. Thin coat applied well. Will top again in a few months.
Robert Wilson

Easy to apply, soaks in well, doesn't set rock solid on the brush between coats.
A very good product, easy to apply, soaks in well. Doesn't set rock solid on the brush between coats. Quick delivery with hour time slot delivery (worth every penny).
Matt Sims

Excellent decking oil
Having tried other products previously, these can sometimes leave a residue as it wears off after winter however I have used this Barrettine Decking Oil for two years in a row and have had no problems, it gives the wood a deep rich colour and the water beads on top. (the deck I have is Yellow Balau hardwood)

Easy to Apply, Covers well
First Coat brush applied, second coat sprayed. Equally good either way !
