Ronseal Decking Oil

Ronseal Decking Oil provides your deck with natural looking protection. It provides a protective barrier against water penetration where constant weathering can cause swelling and warping.

As well as enhancing your deck's beauty and providing superb waterproofing protection, our scuff resistant formula means it also protects against foot traffic.

Before You Start

Old Decking: Use Ronseal Decking Cleaner and Reviver to remove any dust, grease, oil, mildew, algae and other contaminants. Remove any loose, flaking or peeling coatings. For best results and to avoid patchiness remove all previous coatings. Ensure the ends are adequately protected using Ronseal Decking End Grain Protector.

New Decking: The timber should be allowed to weather naturally (usually 6 months) to ensure any pre-treatment has sufficiently eroded to allow penetration and adhesion of the Oil. Clean the deck using Ronseal Decking Cleaner and Reviver, using a scrubbing brush to open the pores of the wood and remove any contamination from the manufacture of the decking. Then rinse thoroughly with clean water, ideally using a pressure washer and allow to dry completely before overcoating. Test effectiveness of cleaning by splashing the deck with water, if beading occurs, re-clean. Retest prior to applying Decking Oil.

The shade label indicates approximate colour only. We recommend you test a small area to determine the final colour which may be influenced by the texture, grain, colour, porosity, type of wood and previous treatment.

Please note that Ronseal Decking Oil cannot be used in conjunction with Ronseal Perfect Finish Decking Oil.
