Ensure the wooden decking is clean, dry, and free from any dirt or loose debris prior to oiling.

New Decking Preparation

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

New Softwood Decking

1. Sweep decking with a stiff brush or broom to remove all surface contaminates such as dirt, grit, and organic matter
2. Use Cuprinol Decking Cleaner to thoroughly clean the deck and remove any mould or algae
3. For best protection, treat decking with a wax-free wood preserver prior to applying Cuprinol UV Guard Decking Oil
4. If possible, preserve all sides including edges end grain prior to installation

New Hardwood Decking

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

Old Decking Preparation

Old coating type finishes such as decking paints, varnishes and varnish type stains must be fully removed back to bare wood before oiling. Depending on the condition and type of finish, it may require more than one attempt to fully remove the old coating.

1. Ensure that all 'coating' type finishes have been fully removed to expose bare wood by either jet washing or using Cuprinol Stain Stripper
2. Sweep the decking with a stiff broom to remove all traces of surface dirt and debris before oiling
3. Any holes, gaps or splits in the decking boards can be filled with Cuprinol All Purpose Wood Filler or Cuprinol Ultra Tough Wood Filler
4. For the best protection, treat with a suitable exterior wood preservative prior to application of Cuprinol UV Decking Oil
5. If possible, preserve all sides including end grain prior to installation

Always do a small test area before beginning any project to assess product performance and results. Follow the manufacturer's instructions on the tin at all times.

Brush Application

Stir thoroughly before and periodically during application to ensure a consistent finish.

1. Apply the oil evenly along the grain, using a suitable brush
2. Do not allow puddles to form and wipe off any excess oil with a clean, lint-free cloth
3. Allow to dry for 4-6 hours
4. Apply a second coat as above

Spray Application

Cuprinol UV Guard Decking Oil can be spray applied using Cuprinol Spray and Brush or other compatible garden pump sprayer. Refer to the sprayer user guide for full instructions.

Do not apply in temperatures below 5°C, in damp conditions or if rain is due before the product has dried. Cover any surfaces nearby to protect from over-spray. Any over-spray should be cleaned up immediately (whilst still wet) with water and household detergent.

1. Spray with the nozzle 15-30cm (6"-12") from the wood surface
2. Spray at a consistent rate to maintain colour depth
3. Take care to avoid over application, removing any excess oil with a clean, lint-free cloth

Decked areas can be cleaned at regular intervals using Cuprinol Decking Cleaner.
