## Description

Product Description Ronseal Ultimate Protection Decking Oil provides superior, natural looking protection, for a longer lasting finish. Our unique formula penetrates deeper into the wood to provide increased durability. Providing a lightly tinted finish it will give double the weather resistance and foot traffic protection, versus standard decking oils. Unique new to market water based Linseed Oil technology Colours and waterproofs your deck in one easy step.Improved resistance against the effects of weathering and foot traffic compared to standard Decking Oils Penetrates deeper which means it gives better adhesion to your deck throughout the year. Gives a more natural look to your deck Rainproof in 90 minutes, Re-coat in 4 hours. Primarily for use on pre-treated decking.Preparation Untreated, weathered decking: For untreated grey and weathered wood use Ronseal 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 and 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. Ensure cut ends are adequately protected using Ronseal Decking End Grain Preserver.New wood: New decking should be allowed to weather naturally (usually 6 months). This will make sure any pre-treatment has eroded allowing the stain to penetrate and adhere to the deck. Clean the deck with 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 timber. Rinse thoroughly with clean water ideally using a pressure washer. Allow to dry fully before over coating.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.

Review: This decking oil is great. Our decking is quite old so after cleaning it with fungicidal cleaner and letting it dry in the hot sun, I used this. It's great stuff and soaked into the wood almost immediately. Initially I put the first coat on a bit too thick which meant that it took a long time to soak in. In fairness the instructions were clear about thin coats - so it was my own fault. It will easily cover a medium sized deck like ours. I did two coats and it looks great. There's a great depth to the colour. I used this oak colour as it was an old deck so it hides the old wear and tear. The water beads off the surface so I know it's definitely doing its job. Two coats was great for our old decking. I'll probably do another very thin coat in the spring to give it a bit of a lift.
Review: Have used this product a couple of times now. It is easy to paint onto the decking and leaves a good finish and a decent colour. You can see it repelling the water following application. The one drawback is that after rain, I have noticed that around the knots in the wood, it leaves some white bubbles which then stain. Will need to reapply every year. Would probably buy again, although might see what other products are recommended.
