  • 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.

Clive Albany
Very easy to apply with minimal coloration of the decking.
I needed to re-oil a deck which had been protected by a French brand of decking oil. This oil was more like a varnish and tended to flake off once weathered. The Ronseal Oil was a milky brown colour but it went on very easily without darkening the wood too much. The coverage for the first coat was alarmingly high but the second coat went on much more economically and 10L was enough for two coats over 30 sqm of ridged decking. NB Ridged decking has about 50% more surface area than smooth decking! Overall Ronseal was easy to apply but only time will tell if it is more enduring than the French brand.

 Natural Cedar
Great product easy to apply
Great decking oil at an affordable price. The rain just stays in droplets on the part where I have treated the decking. Would certainly recommend the product and the company. First Class service. Many thanks.
Good oil, decking looking great afterward.
Bought this decking oil to go an a greyed deck. I power hosed it first, let it dry for a few days and then applied 2 coats of oil on consecutive days. It dries quickly. Once dried it resists rain and standing water seems to sit on top of the decking rather than soaking in. The natural colour is actually a light brown tint, rather than the yellowly look of treated pine boards, so looks nice.

Quality product, does what it promises.
This is my second year with this product from Wood Finishes, and I am entirely satisfied with the product, the supplier , the finish, the delivery and the price.
Robert Crowder
Great product
After trying other products which just stayed on the surface and soon rubbed off, I am pleased that this oil seems to have soaked in well and is protecting the wood.
Susan Tataryn
 Natural Pine
Seems good at the moment
I think we put too much on on the second coat as it has not dried very well. Probably didn't even need a second coat. Seems to be doing the job. Water beading on it. Looks good. See what its like after winter.
William Booty
