  1. Ronseal Ultimate Protection Decking Oil:- provides superior, natural looking protection, for a longer lasting finish.

    Untreated, weathered decking: For untreated grey and weathered wood use a Decking Restorer to restore the deck’s natural colour and provide a sound base for application which ensures the oil penetrates effectively.

    Previously finished decking: Use Ronseal Decking Cleaner & Reviver to remove any dust, grease, oil, mildew, algae and other contaminants. Remove any loose, flaking or peeling coatings. To avoid patchiness, and if using a contrasting colour, make sure you remove all previous finishes using Ronseal Decking Stripper.

    New wood: New decking should be allowed to weather naturally (usually 6 months). This will make sure any pre-treatment has eroded allowing the oil to penetrate and adhere to the deck. Clean the deck with Ronseal Decking Cleaner & Reviver using a scrubbing brush to open the pores of the wood and remove any contamination from the manufacture of the timber. Rinse thoroughly with clean water ideally using a pressure washer. Allow to dry fully before overcoating. Test effectiveness of the cleaning by splashing the deck with water. If beading occurs, re-clean. Retest before applying any 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.

    APPLICATION - Ensure the decking is fully dry. Do not apply in damp conditions or when rain is likely before the product has dried. Do not apply below 10°C. Shake thoroughly before pouring the entire contents into a suitable metal or plastic container. If using more than one tin mix them together. Do not dilute. Apply a “flood coat” using a good quality brush or roller. Apply an even second coat ensuring the oil doesn't pool. Allow 4 hours between coats.

    Usage Areas: Ridged or smooth hardwood and softwood decking.

    Compatibility: Suitable for use on untreated, weathered or previously oiled decking. If using a contrasting colour previous finishes must be fully removed.

    Clean Up: Clean equipment with warm, soapy water.

    Popular colours include dark oak, natural cedar and teak.
