Mould can distort the appearance of your decking. It will form a dark spot on your deck surface, thereby making your decking less appealing. The mould can even penetrate and damage a wood decking board. Not only is wood decking susceptible to mould growth, but mould can also grow on composite decking. If you notice mould growth on your composite decking, getting rid of the mould should be the first thing to do. But, how will you get mould off your composite decking?
What Causes Mould Growth on Decking
Mould can grow on your decking if you fail to maintain it. Wood is more susceptible to mould growth than composite decking. But since composite decking also contains wood, then mould will likely grow on it.
When dead leaves and twigs stay on your decking for a long time without you removing them, it will surely cause mould growth. Remember that outdoor deckings are exposed to the weather and fungus in the air. When debris stays on your decking for long, it will trap moisture on your decking. Composite decking boards that do not have an extra plastic coating on the outside will absorb this moisture, making it easy for mould to grow.
Also, mould will grow on your decking when fungus comes in contact with organic materials like leaves or twigs. If you allow leaves and twigs on your decking surface, you will start noticing a dark spot on your decking, which is a sign of mould growth. Mould can cause early damage to composite decking if you don’t get the mould off.
