Timber decking guide - Maintenance

The degree of maintenance required depends on the deck specification. DeckMarkTM quality assessed components require no further preservative treatment. They will resist decay almost indefinitely and can be expected to last in excess of 25 years.

A water repellent coating, may be used to improve deck performance by helping to reduce the occurrance of small cracks. If used, water repellents should be applied every other year - preferably at the end of summer. It is now possible to specify decking timbers that include water repellents as part of the pressure pre-treatment process.

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.

Whether smooth faced, grooved or ribbed deck boards are preferred, 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 power spray or proprietary cleaner to lift any stubborn stains.

DeckMarkTM quality assessed deck-care products such as water repellents, stains, deck cleaners, and end seal preservatives are all available from within the TDA.
