Deck Maintenance

Well designed, specified and constructed timber decking needs minimal annual maintenance to keep it in good condition.

The degree of maintenance required depends upon many factors such as product quality, species and location.

  • Whether smooth faced, grooved or ribbed deck boards, timber or wpc, it is important that the deck surface is kept clean by regular brushing with a stiff bristle brush to remove dirt, algae and dead leaves which could make the deck slippery in the wet.

  • At least once a year - preferably in spring - give decks a more thorough cleaning using a mild soap solution or proprietary cleaner to lift any stubborn stains. If you use a power spray, please take extra care not to damage the surface of the deck.

  • A water repellent coating may be used to improve the appearance of the deck by nourishing the wood. If used, water repellents should be applied every other year - preferably at the end of summer.

    It is possible to specify decking timbers that include water repellents as part of the pressure pre-treatment process. In this case it is possible to top up the water repellency with a suitable brush on product as and when required.

  • Decorative stains will also need to be refreshed periodically to maintain their appearance - usually depending on location, amount of sun received and general wear and tear.
