  • 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.

Mark Webb

Great price and fast I wish all companies was like this.

 Natural Oak
Does what it says on the tin! but to get a really good finish, you needs a bit of time spent on the preparation. Otherwise you don't get an even colour or a uneven surface
R Bird

 Natural Cedar
I have used Ronseal decking oil before with good results.
I built a large new deck and sprayed this on to get a nice even Finish. Very pleased with the result . My new deck is now well protected for the winter and I will certainly use it again next year.

Best price I found on the net and rapid delivery
Dries in a few hours. It darkens the wood a little like oil does but other than that it is clear. Make sure you wipe off all excess oil or you will get darker patches where the oil was thickest. I used a rag to wipe off the excess after applying with a brush.

Norman Jenkins

Excellent product.
The experience of buying this product was the easiest I have come across. No hassle and to be able to track your item was fantastic.
Michael Richardson

Easy to use and covers well
The product is good. I wish personally that I had chosen a coloured wood cover to show up more easily that it had been treated. Even so, it works well. Great price. Quick delivery.

 Natural Pine
Looks great even better after a week or too when the true colour shows through. would recommend and will purchase again.

Like all Ronseal products it does what it says on the tin.
Only time will tell if it lives up to the initial promise. Used it to give the final finish and seal to my new deck, adjacent outhouse, timber cladding and refurbished picnic table which had all been first treated with 2 coats of coloured wood preserver. It has given a pleasant satin sheen to the treated wood and revitalised the somewhat tired picnic table, although that did benefit from being re-finished as well. Rainwater forms up in globules all over the treated timberwork so it is obviously doing its job and not allowing it to soak into the wood.
