    One of the best ways to refresh your decking is to give it a good clean. Before applying the Cuprinol Decking Cleaner remove any excess dirt debris or loose wood from the deck. It’s also a great time to check the surface of the decking for loose screws or boards and ensure these are tightened.


    Before applying the product test a small area on the surface to be cleaned.

  • For heavy mould and algal growth apply undiluted
  • For lighter growth dilute with an equal amount of water
  • Apply generously by brush, spray or watering can (with rose attached)
  • Scrub affected areas with a stiff brush, leave for a few minutes and then rinse off with water
  • Apply only in dry conditions, above 5°C and when bad weather is not forecast
  • Once dry apply an oil or stain to protect the decking such as Cuprinol Anti Slip Decking Stain or Cuprinol UV Decking Oil
  • Note: Always follow the manufacturer instructions found on the tin.
