  • 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.

Did exactly what it said on the tin made very good coverage
At first not really sure if changing from clear to teak was good for patio but has done real good job as it covered well and retained the timber markings I required thoroughly recommended.

Excellent service- very quick delivery
Excellent service- very quick delivery- I would 100% recommend wood finishes direct- My 5 year old decking looks like new.
Terry Reece

Very good product!
Having jet-washed some 60 sq.metres of decking plus rails,spindles and posts I decided to try the Ronseal oil as it dried faster than other products. It transformed the whitish-grey timber into a beautiful light honey colour, showing off all the grain and knotting. The wood is 7-8 years old and now looks like new......well, better than new. Use 2 coats for best results, a Mako brush for all spindles etc and the decking applicator sponge for the deck itself. Its also best to carefully jet-wash the timber to get all the dirt/grime off. I used some Ronseal decking cleaner/reviver on the deck and it is well-worth the investment as it goes a long way (wet the wood first and broom it on) and lifts dirt and water-based paint.
