  • 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.

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.


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.

 Natural Pine
Great Stuff,it's true "Does excatly what it says on the tin"
Really good quality product,best that I have used over the years.
Easy to paint on,covers well,nice finish.
Decking could still be slippy when wet.A grit based coat may now be required.The product itself looks great.
Peter Roberts

 Natural Pine
Used it before, although I'm no authority, we found this product easy to use.
We found the decking oil, better than the decking stain. We found the decking stain lifts off after a couple of years, the oil needs to be applied but doesn't build up or peel off, therefore it doesn't look unsitely.

 Natural Oak
Used with the recommended applicator enables a clear, smooth and faultless finish. It does not disguise the wood and so far appears to be robust to weather and human traffic!
William Baron
Brilliant product, will use again this coming year...
Good coverage, brilliant finish. It was a little darker than I thought and needed two coats but I am more than happy with the results.
Pete S
It is as stated on the tin tried other makes in the past found Ronseal to be the best
Have used this product for the past 6 years on our decking which is on the coast, have applied as recommended and have found the results to be excellent.
Jeanette Williams
 Natural Cedar
Much cheaper than local builders merchant and delivery came within two days, unbelievable
Have used this product previously but unfortunately cannot get the mahogany at a reasonble price anywhere and have therefore gone for the cedar so not sure what colour will be like as am waiting for weather to change to give it one coat before winter. We were happy with the finish previously.
 Natural Cedar
Good coverage
Stuart Marsh
Took this product out to France to treat our decking, easily applied with good coverage. Did exactly as it said on the tin, will certainly used again.
Great product, easy to use
What more can I say, just great.
J Roberts
Perfect product delivered fast and at a very competative price.
Used on a relatively new decking project, the oil slightly darkens the timber to a beautiful light golden honey colour allowing the natural wood grain to stand out. As always, follow the instructions and ensure there is no chance of rain when you apply the product.
