  • Overview


Ronseal Decking Oil Natural is a deep penetrating formula that feeds your decking, restoring the natural oils lost over time through weathering. Suitable for hardwood and soft wood decking, It penetrates the wood leaving a natural looking finish that both protects and nourishes.


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.


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.


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.

Equipment Cleaning

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.

Super fast service good price
Daniel Groves

Excellent service fast and cheap
I ordered this while I was in B&Q about to get 3 tins of ronseal decking oil that cost £39 a tin and I thought that was really expensive. So I had a quick look online and found Wood Finishes Direct was doing the exact same tins for £24 a tin. I ordered it in 5 minutes and was delivered the next day - and i saved almost £50! I would recommend this company and I will definitely use them again.

This is the same product you buy in B&Q,for £35-£40 for the same 5 litre tin!! Superb stuff--i use a pump up pressure sprayer;it takes next to no time.I have used other products this way,but because it seemed to be old stock,was full of cured bits which clogged the sprayer.Not this!! Only two stoppages out of 35 litres.Really excellent product and great value.

Unbeatable price
Does what it says on the tin remarkable finish on our Q-Deck great comments from family and friends. Easy to apply on large areas with Ronseal decking pk and using lint free rag to smaller areas very pleased with Ronseal.

Second Order of Same Product
All theoretical covering estimates in metres-squared per litre are optimistic when I operate in the real world. I anticipated using what I needed on thirsty decking, and ordered quantities as appropriate. The modest cost allowed a generous rate of application, within overall reasonable cost limitations. This was my second purchase to have in stock for a 2015 re-application.
Colin Hunt

A quality oil which has added new life to our decking. Easy to apply by brush

I've tried all the rest but Ronseal is still the best decking oil available.
An excellent product that protects for a far longer time than that of competitors. The most expensive but you get what you pay for.
