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. This process is not necessary for softwood decking.

Note: The 'Natural' version of this product has a slight tint to provide UV protection to the timber. "Natural" offers a clear, wet look, whilst "Cedar", "Oak" and "Pine" dry to a translucent coloured finish.

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: 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.

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.

Lovely warm colour Easy to apply by Theresa

This oil is fab. It rained since I applied it and the water just site on the top of the wood. The oil was really easy to apply with a long handled pad, and it looks a lovely warm colour. I love it.

Does the job by Andy Owen

Easy to apply (it is very runny though, you will get lots of splash). Rained hard the day after I finished and the beading is a delight to see. Looks good & finish feels good.

Excellent Product by Paul Lofting

Ronseal decking oil was easy to apply covered well and is protecting the natural finish of the wood. Rain tested the day after application the oil did its job, the water ran off the decking. Will use again - highly recommended.
