## Description

From the manufacturer Ronseal Ultimate Protection Decking Oil Natural Oak 5L Nourish your decking while giving it a beautiful natural finish with Ultimate Protection Decking Oil. It’s tough against changeable weather conditions and can cope with general wear and tear. It also lasts twice as long as other decking oils so you can enjoy a good looking decking for longer. Restore the natural look of your wood Rainproof in 90 minutes Stops wood from greying and splitting Lasts twice as long as standard oils Restores wood oils lost through weathering How to use Ultimate Protection Decking Oil Before you start The oil works its magic on dry days when the temperature is above 10°C. Make sure your decking is com pletely dry before you apply it too. Application Give the oil a good shake and pour the contents into a suitable metal or plastic container. If you’re using more than one tin, mix them together but don’t dilute! Apply a generous amount of oil to the decking using a brush or roller. Paint with the grain and focus on three to four boards at a time to ensure you don’t get any overlap lines. Wait four hours for the coat to dry. Once the first coat has dried, apply a s eco nd coat and wait four hours for it to dry. And that’s it! Your decking is now oiled and healthy.

Review: Great on waxed decking - Created a patio using “waxed” decking. This applies evenly, smoothly and allows the natural colour of the decking to shine through - so applies as a translucent oil which enhances the natural wood colour and not a stain. Covers well when applied with a good quality brush. Touch dry within 4 hours, fully useable within 24 hours. Rain sits on the decking. Having used this for about 5 years, I can honestly say that it is very anti-slip. The price has fluctuated and it’s now considerably more expensive than when I first used it but great quality, functionality / use and, most importantly - non-slip.
Review: Revived our decking - 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.

## Questions & Answers

**Q: Water based???? No it’s oil surely??**
A: It’s an acrylic polymer suspended under a water thinable linseed oil

**Q: Is there anything that can be painted over this? Used on very old decking (after cleaning etc) but it still looks pretty awful.**
A: I had the same issue. Its basically a protector,like putting vanish on! 
I painted  mine with decking paint. AMAZING RESULT. 
But you def need to paint it as if from a clean slate..

**Q: Is it oil based**
A: It says 'decking oil' on the container, so I'm assuming it is an oil of some description. I've been using it since I built my decking 7 years ago and it still looks good.

**Q: Can i use this product on my wood floor in my lounge.**
A: Good Morning,

Thank you for your enquiry.

As a general rule, we cannot recommend application of an exterior product to an interior surface, as they need different types of protection. Interior surfaces require the finish to be tough against knocks and scratches, whereas exterior surfaces need water repellency as well as flexibility to adjust to constant temperature changes as well as protection against mould and rot.  If you woudl like us to offer further advice, feel free to get in touch on 01303 213 838.With any product we always recommend  a test area first.

### ⭐⭐⭐⭐ A good choice from a range of decking protection products
*by J***M on 17 October 2017*

There is a rather confusing array of products when it comes to decking oils/stains/protectors etc. I had to do some research to differentiate the products. Briefly; - Decking Stains are water based which form a protective top-coating in the selected colour. This topcoat protects from water and sunlight damage to the wood, and it provides the most protection. The downside is that it can peel with time and leave a very scrappy appearance. - Decking Oils are oil-based, and absorbed into the wood replacing natural oils rather than sitting on the surface. These are coloured (even natural) to protect against UV, and the oil prevents water penetrating the wood. The advantage is because it isn't like a surface paint, it will not peel with time and so can be readily re-oiled with less preparation. They contain a pigment for UV protection, but offer lower weather-proofing than decking stains (according to claims). - Decking Protectors are waxed based, and provide a waxy waterproof coat when dry. Again, this is a surface water protector which can flake/peel over time. - Wood preservers which are solvents containing anti-fungal and insecticide compounds. The solvent carries these into the wood helping to prevent insect and fungal decay. Most (probably all) decking has been pressure pretreated in a similar manner making wood preservatives unnecessary. However some treating of the cut ends and knots etc. is a good idea. Having said that the Ronseal Ultimate Decking Oil and Ronseal Decking Oil (regular) are slightly different. Although both are decking oils, the Ultimate is actually water-based, whereas the regular Decking Oil is a traditional oil-based product. The easiest way to differentiate is to look at the brush cleaning instructions; if it says 'wash brushes in water' it is water-based, whereas if it says 'use white-spirit' (or similar) it is an oil-based product. It seems a bit contradictory to have a water-based oil, but Ronseal claim this is a new linseed oil based technology, and offers greater protection over traditional decking oil. It seems to me more like an emulsion than an oil. So, my experience. It is very easy to apply with a fence-type coarse brush and permeates the contours of the decking easily. The 'natural' actually has a slight tint which offers UV protection and slightly darkens the wood to a shade similar to it having been wetted by rain. However, I thought this added pleasing and even colour. The natural oil looks a bit like café latte, smells of linseed oil, but does foam slightly on agitation, although this is not a problem. The smell is only slight but it does remind me of oiling a cricket bat. It is claimed to be rain proof in about 90 minutes. I didn't test this, but did notice the next day it had left in places, mainly in the grooves, left a slight residue a bit like light brown curds. I assume this is where there was slightly larger amounts of the oil and the residue was left on drying. Many have commented on this, but for me it brushed off readily and any remainder faded or was washed away leaving nothing permanent. However, it does suggest the formulation is not optimal. Personally I didn't notice any real tackiness the next day, and thought the finish was good; quite even, and a slight dull sheen as if it had been oiled, but not at all slippery (no change to grip). Rain water sits on the surface. In terms of coverage, it is claimed to cover 20m2 of grooved decking with two coats, but in my hands I would estimate more like 15-16m2 (and I didn't think I was being particularly liberal in application), so that's about 25% less than Ronseal claim. In all, I am pleased with the finish, found any issues (slight transient residues and less coverage) to be small, and would recommend as a suitable decking choice. However, I guess time will tell whether the protective properties are good! Last, and not least, the current price on this site is good compared with local DIY stores.
