Use any cleaning agents you may have at home to scrub the area. That’s how to remove mold from deck. Mold thrives in cool and damp places, so your deck is an excellent breeding ground for this fungus.
Mold On Your Deck
Your deck is exposed to moisture and all kinds of weather, so expect that mold will grow after some time. Mold is usually just an eye-sore that doesn’t have health implications, but you need to check and do the suitable preventive measures to be secure.
This mold is the most common type you will see on wood. It thrives in damp, moist, and shady areas.
Green mold has several species like Cladosporium, Penicillin, and Aspergillum. They all share a greenish hue that looks like algae. Green mold isn’t a significant risk when it’s in an open-air area, but you still need to take precautions from the spores.
Black mold is something you should be more concerned about. This mold doesn’t usually grow on decks, but the Stachybotrys chartarum fungus can cause severe respiratory issues when you inhale its spores.
This mold grows on wood with high cellulose like gypsum board and fiberboard exposed to moisture. So, if you have these materials on your deck, watch out for black mold.
Causes Of Mold Growth Outdoors
Mold thrives in a moist environment, so a deck that constantly gets moisture is the perfect breeding ground for these fungi. External factors like leaf litter, airborne pollen, and fertilizer overspray can trigger a mold infestation. If your wood isn’t appropriately sealed, then it will be more vulnerable to mold.
Minimal sunlight can also make your deck a breeding ground for mold spores. Check out this article to learn more about why green mold grows.
