Understanding Mould Growth on Timber Decks

What Causes Mould?

Mould loves damp places and can grow almost anywhere with a bit of moisture. It needs moisture, oxygen, a host (like timber), and humidity to grow. Mould spores are always in the air, landing on surfaces like timber decks to feed and grow into dark spots.

Heavy rain and floods in places like Queensland, New South Wales, and Victoria have made mould more common on timber decks. Mould does well in damp, humid conditions, so checking your deck often is important.

Things like poor drainage, not enough sunlight, and high humidity can make mould grow on your deck. If not stopped, mould can harm the look and strength of timber, metal, or composite decking. It's vital to stop mould to keep your outdoor area looking good.

In Australia, many people choose timber decking for their outdoor spaces. But these wood surfaces can get mould if not looked after. To keep your deck in top shape, stay ahead of mould by fixing the causes and preventing it.

Effective Methods for Removing Mould

Dealing with mould on your timber decking can take a lot of time, especially if it's already spread. It's important to act early to prevent bigger problems. Avoid using a pressure washer as it can push the mould deeper into the wood, making things worse.

A softer approach works better. You can try a mix of detergent and water or bleach and water to clean most deck finishes. Always follow the advice from the manufacturer or supplier. For tough mould, you might need to use a special mould removal product and apply it several times to get rid of it completely.

After removing the mould, applying a deck sealant or mould inhibitor is a good step. This helps stop mould from coming back, especially in places where mould grows easily. Leaving timber untreated can let spores take hold quickly.

If you're not sure how to remove mould from your decking, talk to a decking specialist. They can tell you the best and safest ways to clean your deck. This way, you can enjoy your deck for many years without mould problems.
