  • 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.

Note: The 'Natural' version of this product has a slight tint to provide UV protection to the timber.


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. Note: This process is not necessary for softwood decking.


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: this product is 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.

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.

Best value / best finish decking protection
Having used this make and several others over the years, I can recommend this one as the best out there at a sensible cost. Great results every time means my decking at 10 years old looks superb, not new but nourished and ready for another season.
