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.

Exactly as advertised covers better than I anticipated as it is quite liquid by Mrs.C.Allan

Good coverage but needs at least two coats

Applied easily and dries out well although it was applied in hot weather by M Bakewell

Product looks nice with light tan finish (natural colour used) applies easily, can splash but this indicates it is thin enough to penetrate wood well. Cannot comment on how long it will protect for as yet. I used it on a fence not decking but it seems ideal for any wood outside.

Does the job But colour differed from what we bought earlier by Nikhil Bhat

Does the job well. Only reason it's not rated higher is because the colour was different from a can we had bought from another supplier. Both were supposed to be 'Natural' colour.

A note from us...


Thank you for your feedback on this product, the 'Natural' does have a slight tint ( please see preparation, above ) to it but this gives the same finish as many many other clear products in that it darkens the wood and give what we call the 'wet look'. The reason for this is to increase the UV protection of the product, many clears offer little or no UV protection and so this very small amount is designed to act as a filter against the sun. I hope that helps and please do let me know if you have any further questions.

Kind regards Sam.

Easy to use by David Royle

it dryes to leave waterproof coating on the wood that the rain runs off as if the wood has been waxed. I have used it on my decking, garden furniture and onto the bare wood after I built a shed. It stops the wood discolouring with dirt as well as giving protection from the weather. I have used it on all the wooden things in the garden.

It was applyed using a spray gun, I used it on my garden fence as recommended by the fence erector, it works well, this will be my second application of oil in 2 years, fence still looks as good as it did when first errected 2 years ago. I will use the product again in 2 yeas time to help keep it that way.
