How to Clean a Hardwood Deck


Watch our series of How-to videos on cleaning a hardwood deck

To restore dark or grey timber to its original state, you'll need to apply Sikkens Cetol Deck and Wood Cleaner.

Step one, before application with the timber to delay drying out during the cleaning process. The surface must remain wet for 15 minutes.

Step two, apply Cetol BL Deck and Wood Cleaner using a bucket and mop evenly across the whole deck.

Step three, work this into the timber using a stiff bristle brush and allow to rest for 15 to 30 minutes, but don't let it dry out. The deck should lighten in colour.

Step four, wash the residue from the deck with a pressure washer or a stiff bristle brush and garden hose on high pressure and allow to completely dry.

After following these steps. Your deck is now clean and ready for your desired Sikkens Cetol coating.
