In our last post, we mentioned the resources the North American Deck and Rail Association (NADRA) provided regarding mold growth on decks. With all the rain we’ve received in Maryland during the last couple weeks, we thought it would be appropriate to focus on this topic
The high level of humidity and standing water makes conditions ideal for mold to spread. Moisture is one of the vital ingredients mold needs to grow, so if there’s a place on your deck that remains wet or collects water, you should dry it within 24-48 hours (the time it takes mold spores to germinate) of it becoming wet. It’s helpful to make sure you don’t have overflowing or leaky gutters and downspouts contributing to the problem.
Another thing mold needs to grow is food, and unfortunately, mother nature provides a lot of it. Mold can feed off of dust, pollen, and a wide variety of organic material. Therefore, one way of preventing mold growth is to keep your deck swept clean.
Should you see mold growing on your deck, you need to quickly clean it before it spreads to other parts of the deck or, even worse, inside your home. The article suggests a number of ways to clean mold so make sure you check it out before taking action.
