  • 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.

 Natural Pine
Excellent product!
Easy to use and a little goes a long way. Put two coats on decking which had been power washed and it looks as good as new! Rain now sits on top of it instead of soaking into the wood. Would definitely use this product again!

Very good product, used for many years, highly recommended.

Company does what it says on the tin
I always feel worried about buying products on line which are clearly cheaper than any other source, but having decided to give it a try I would recommend wood finishes direct to all. The product is great, its Ronseal, its as expected, the delivery was rapid and the free phone service they have help allay my original worries that its too good to but true, but it is.
Debra Moran

Easy to use , leaves great finish on new decking
Bought this item at really good price from wood finishes direct excellent service , speedy delivery.
Jason Spicer

Great product that when applied using a good brush went on evenly without leaving the boards patchy. Two coats applied over two of the hottest days of the year but I would still say that it is very easy to apply. Result is great looking decking which beads if rained on, also didn't expect it but it almost seems grippy in the wet, bonus!
Roger Boud

Great product to use,pleasant odour,soaked into the decking boards quickly and left a good clean finish. No worries about oil making the decking slippery,the boards remain dry.Decking looks like new and the finish seems to last.

 Natural Cedar
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.
