After installation, the deck must be swept and cleaned to remove metal filings from drilling, nailing or other construction that may cause black spots on the deck when exposed to the elements. We recommend applying a timber finish to protect it once the deck has been installed. Do not leave your deck unfinished. If the deck has turned grey from natural weathering or has been discoloured due to metal filings, a solution of oxalic acid crystals mixed with water will help bring it back to its original beauty.
Maintaining your deck
Timber decking is typically made from Class 1 or 2 hardwood or Cypress timbers, or from an H3 treated pine. All three decking products, regardless of their durability, benefit from a coating of timber finish, after the deck is installed. Using a timber finish promotes timber endurance for the life of your deck.

Using a timber finish will help prevent this occurring.
How often should I maintain my deck?
Hardwood and Cypress decking is exposed to the elements and it is important to protect your deck. To preserve the colour of the timber species and improve the life of the deck, apply a decking finish to the exposed surfaces. Re-apply according to the manufacturer’s instructions.
We recommend washing your deck down with one of our cleaning products around once per year. Simply re-apply the timber finish of your choice as there is generally no need to sand your deck back prior to reapplying your finish.
