Manns Premier UV Decking Oil can be used on all pre-treated, pressure treated and preservative impregnated decking timbers, and is also suitable for use on wooden sheds, fences and pergolas.

Ensure decked areas to be oiled are clean, dry and free from surface dirt and debris.

New Decking Preparation

For all bare wood decking including tantalised, pressure treated and preservative impregnated decking timbers.

New Softwood Decking

  1. First treat decking with a suitable exterior wood preservative for the best protection
  2. If possible, preserve all sides including end grain prior to installation
  3. Sweep the decking with a stiff broom to remove all traces of surface dirt and debris
  4. Use a suitable garden decking cleaner if required before oiling

New Hardwood Decking

Hardwood decking usually requires a period of weathering to allow the surface grain to open up. This allows for better absorption of the decking oil. Check the decking manufacturer's guidance on how long decking should be left to weather before treating.

Old Decking Preparation

Manns UV Decking Oil cannot be used over timber that has been painted with conventional paints, varnished or lacquered. Any old surface coatings must be fully removed to expose bare wood before the wood can be oiled.

  1. Ensure that all 'coating' type finishes have been fully removed by either jet washing or using a dedicated decking stripper
  2. Old oil finishes should be cleaned thoroughly with a suitable decking cleaner
  3. For decking and other surfaces that are or have been affected by mould, algae or black patches, treat the wood with Barrettine Mould and Mildew Cleaner prior to applying decking oil
  4. For the best protection, also consider Barrettine Premier Wood Preservative to help protect against mould, algae, dry rot, woodworm and wood related diseases
  5. If possible, preserve all sides including end grain prior to installation
  6. Wood preservative should be allowed to dry for a minimum of 24 hours before applying Manns UV Decking Oil
  7. Sweep the decking with a stiff broom to remove all traces of surface dirt and debris before oiling

Always do a small test area before starting any project and follow the manufacturer's instructions on the tin at all times. Stir well before and during application.

  1. Apply an even coat of Manns UV Decking Oil to all surfaces to ensure optimum performance
  2. For the best results, apply to all sides of decking and other timber including sawn ends
  3. Allow up to 12 hours drying time between coats

To restore decked areas that have become worn or dry looking, an additional coat of Manns Premier UV Decking Oil may be applied, following the Application instructions above.

Goes on easily and gives great coverage. Now decking is waterproof and rain beads on top. Not slippery once applied.

A little goes a long way by Steve Seyboth

I applied this to smooth decking with an applicator sponge to decking that's 3.5m x 4.8m. I did two coats & still have about 2/3 of the 5ltr tin left. Water beads up like a newly waxed car. Great stuff.

So far so good by Malcolm Walker

Used on a large decking area. Easy to apply with brush and good coverage. Similar affect to when you wax a car, rain water beads just sit on top. If Continues will use again next year

Covers great and protects from water by Mr Nikki Lynch

The Mans (UV decking oil) is great stuff by Marcus Rex

The product itself (UV decking oil) is great, we really like how it keeps the wood looking its natural colour. We use the clear version and it definitely lasts well and protects the wood from harmful UV and stops it bleaching out. My only complaint is they have swapped from a square container that was easy to pour from to a round paint can, which is not easy to pour from. We use spray system to apply the product as there is such a large area to do, trying to pour from a round tin is messy to say the least. Also round tins take up more space than square ones when packed in boxes, meaning bigger boxes and more waste packing! Over all though this is a really good product, I'd say its the best wood treatment I've ever used, it is better than well known brands in terms of use of use, coverage, protection afforded and longevity. I also found Wood Finishes Direct to be extremely helpful and give great customer service.

The best of British by Neil Bate

Used many stains and oils over the years. Thought I would try Manns Decking Oil as it was a reasonable price and it was made in the UK. So this oil gives off a rich finish and just I instinctively perceive it as better look, feel, application. Since then I have re-purchased this oil and have now done all the decking throughout. Really happy with the look and feel of the wood once its gone off. Happy to recommend.
