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.

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.

Excellent finish and seems to be the ultimate water repellent by Elizabeth Capper

We have used the product on our new wooden gate. On applying it, we found it certainly goes a long way and leaves a great finish. We did 2 coats, which gave a fantastic deeper colour. All in all, can't fault it !

Easy application, quick drying by Paul I'Anson

The finish is slightly redder than expected but the overall finish is great. It looks good but more importantly it repels rainwater.

Easy to use seems to have done the job by Catherine Campos

Bought to light oak version which was a bit darker/redder than I was expecting but went on really well and rain sat on top rather than soaking in after application

Thought this decking oil might struggle after a cloudburst before it was properly dry but it seems to be doing the trick Very happy with the product by Jackie Hutchison

Least expensive but excellent product by Julian Bond

The decking oil was used on new, softwood decking as a preparation for the Osmo non slip decking treatment. It was easy to apply, dried quickly and when it rained the following day the decking oil repealed the water remarkably well. It went further and used less than I'd expected. There were more expensive products but I can't see that these would out perform the Barretine. I'd reccomend this product - the decking looks great once treated, one coat performed really well and I'd suggest it would be absolutely fine on its own - without the Osmo.

Very good and the water just beads away by Robert Shirley

Easy to apply good quality product and would definitely purchase again at the price. Saved over £15 on other brands however, can't comment on their performance having not used them to compare.

It works well by Peter McAnearney

Used this product last year on some decking steps. It showed no signs of weathering or of wear. To use it again shows the faith I have in this product. You can buy cheaper but this is the best.

Easy to use and enhances the wood by Harry Baxter

I have used this product on decking and pressure treated fencing using a garden sprayer. The oil went onto the wood easily and gave the wood a golden colour. I have used the oil to protect the wood over winter and will again be using it in spring to protect against the sun. GOOD PRODUCT.
