Decking areas should be thoroughly cleaned to remove dust, dirt, algae, mildew and other contaminates from the surface prior to oiling. For the best results, clean with an appropriate Decking Cleaner allowing the decking to dry thoroughly before applying the oil.

Ronseal Decking Oil can be used over previous decking oils, however other types of decking stains and treatments that act as a sealant or varnish will need to be removed before application.

New or freshly stripped / cleaned decking can be treated with a Decking Preserver prior to applying the decking oil. This helps to protect the timber of the decking from fungi, dry rot & mould.

Ronseal recommend that new decking made from dense exotic hardwoods should be left to weather for a period of 6 months before applying decking oil. This allows the tight grain of these woods to 'open up', allowing the decking oil to be more easily absorbed by the timber. This process is not necessary for softwood decking.

Note: The 'Natural' version of this product has a slight tint to provide UV protection to the timber. "Natural" offers a clear, wet look, whilst "Cedar", "Oak" and "Pine" dry to a translucent coloured finish.

Do not apply Ronseal Decking Oil in wet conditions or if rain, frost or snow is likely before the product is dry.

  • Decking areas should be completely dry before application
  • Decking oil must be thoroughly stirred before and during application
  • Apply oil to the decking with a good quality roller or bristle brush
  • Apply a second coat in the same way as the first.
  • Allow 6 hours between coats

Two coats of Ronseal Decking Oil are usually sufficient but this may vary depending on the type of decking timber and its absorbency.

Note: Not compatible with Ronseal Perfect Finish Decking Oil

To keep your decking performing its very best brush off leaves, dirt and debris on a weekly basis. If signs of mould appear use an appropriate decking cleaner. The condition of the decking should be inspected on a 6 monthly basis and can be re-coated as required.

Brushes should be cleaned immediately after use with White Spirit. Remove as much of the decking oil from brushes and other application equipment before cleaning. Any remaining decking oil should be stored or disposed of properly at a local authority site. Do not empty into drains or watercourses.

Wear suitable gloves and clothing when using this product. Ronseal Decking Oil is Harmful to aquatic organisms, may cause long term adverse effects in the aquatic environment.

Excellent product by Richard Ellis

I have used this product before to protect a cedar pergola. It is easy to apply and goes a long way. It lasted for many years before requiring recoating.

Lovely colour Does what it says on the tin by Mrs Morag Skene

Delivered before the date quoted. Well packaged. Very good price compared to other sites and even had 25% extra free - bonus. Very easy to apply although being quite thin it can splash and drip easily so needs to be applied with a light hand. Lovely colour. Has restored my decking to it's former glory plus protects the wood from wet what more can you want

Looks great, no issues by Peter

Very effective. Just be prepared to get way more than the instructions say is required. The first coat especially absorbs quickly and requires a lot of oil. But works and looks great if you have made the effort to prepare the decking for coverage.

Does the job! by Pamela Mcfarlane

My deck was very split & neglected. It had had no product on it for 3 years and is south facing, so gets the full brunt of the sun all year. I sanded my deck, which had aged to a grey colour and used 3 coats of this product as, the deck was very porous. The finished result is a very rich colour. A lot darker than I was expecting (darker with each coat), but it looks as good as new and the rain now beads on it really well. I'm going to try to make sure I keep on top of maintenance now and give it at least one coat, preferably two per year. I think it's going to need it with its sunny position. As its a big deck, I've used a lot of cans of product, but this company has made it financially possible as, they are the cheapest, by a long shot! Great service and fast delivery! I'll definately be using again. Thank you :-)
