How to use Decking Protector

Before you start

Clean your decking and remove dust, dirt, grease and oil. A stiff wire brush should be able to dislodge a lot of dirt.

How to prepare new decking for protecting

The majority of new decking is suitable for protecting including tanalised, pressure treated and preservative impregnated decking.

You need to let your decking weather for roughly six months to ensure the grain opens up and any pre-treatments have washed away.

You then need to clean the decking to remove dirt and dust. If you notice any mould or algae, use decking cleaner to remove it.

How to prepare old decking for protection

All old coatings need to be removed from the decking before you can apply the protector.

  1. Use decking stripper or a jet washer to remove all the old coating and strip back to the bare wood.
  2. Clean the decking with specialist cleaner.
  3. Leave your decking to thoroughly dry.


Decking Protector is best applied on days when the weather is above 10 °C and no rain is forecast.

  1. Shake the tin thoroughly to ensure it’s all mixed together.
  2. Pour the Decking Protector into a plastic container.
  3. Use a brush, roller or low pressure spray to apply the protector. If you use a sprayer you will need to protect the surrounding area from overspray.
  4. Work the protector into the wood grain.
  5. If, after 15 minutes, you notice any protector pooling or ponding, redistribute it to dry areas.
  6. Wait for a maximum of two hours for the first coat to dry. Drying times can vary though depending on the weather conditions and the type of wood you’re protecting.
  7. Reapply a second coat and wait 20 minutes before redistributing pooling protector with a dry brush.
  8. Wait 24 hours for the decking to dry completely before moving back furniture.



Brushes can be cleaned with water and detergent.

Keep your deck well maintained and use a wire brush to regularly clean it to remove the dirt and dust.

If you notice a build-up of any leaves, grime and mould, use a deck cleaner to remove this dirt to keep the finish of your deck looking good.


Inspect the finish of your decking on an annual basis to look for any patches or scuffs that need repairing. To fix this, all you need to do is apply another coat of the decking protector and it will look good as new.
