Our premium grade, advanced formulation Decking Oil will protect and maintain all types of wooden decking while enhancing the grain and bring out the natural beauty of the wood. The oil will dry to a hard, durable, highly attractive satin finish and will never crack peel or flake.    

Its deep penetrating action will feed and nourish all garden decking timbers while not only providing excellent water repellency, but will help prevent cracking, warping, splitting and swelling which will prolong the life of your decking.

Containing UV filters, our Decking Oil will also help protect against sun damage while also helping to prevent the growth of mould, mildew and fungi.      

Suitable For

Our Decking Oil is ideal for all types of bare soft or hard wood, preserved or pressure treated decking boards.

Coverage & Shelf Life

5 litres of Decking Oil is enough to treat roughly 25m² of decking (2 coats)

Store in a cool, dry place, away from direct sunlight between 10°C and 25°C.

Once open, use within 3 years.

Keep out of reach of children.


Most new decking is slightly waterproof, and this protection could stop the oil from soaking in properly. To oil new decking, you need to first clean off the waterproof protection. Do this with our Decking Cleaner.


Clean the decking first with our Decking Cleaner to restore it to its original colour. This will remove all dirt and green staining caused by mould and algae; greatly improving the results of the Decking Oil.


Remove any loose, flaking or peeling old finishes from previously coated surfaces. Our Decking Cleaner and a good scrub should achieve this, but you may need to use a Paint Stripper on some painted surfaces. 


Surfaces must be clean and dry. Shake or stir thoroughly. Apply liberally with a suitable brush, moving in the direction of the grain. Be sure to cover all the wood, including any edges, for maximum protection. Leave for 5 minutes for the oil to penetrate into the wood and then wipe off any excess with a clean brush or lint free cloth.


The item will be showerproof in two hours, depending on temperature and humidity conditions. Allow four hours drying time between coats and apply a second coat in the same way as the first.  


Simply remove as much product from your brush as possible and then clean in warm soapy water.


To conserve the performance and look of the oiled finish, you should sweep decked areas with a stiff broom on a regular basis to remove any loose dirt, leaves or any other contaminants which can degrade the decking finish or timber over time. 

Depending on how much traffic the decking is subjected to, and how much weathering it receives, the decking should be inspected on a regular basis and be retreated with a maintenance coat of the Decking Oil once you can see it starting to look a little worn and tired or when water is no longer being repelled. Simply clean the area to be maintained and apply a thin coat of oil in that area.
