A deck can be a wonderful addition to your home but only if it remains strong and mold-free. Mold is one of the biggest enemies of a deck. With moisture being present outdoors, the mold is bound to find its way onto and into your deck. Typically, mold will begin to appear on the more shaded sides of a deck. Anywhere there is less sun means there is more moisture, making conditions ideal for mold growth.
Once mold infiltrates a surface it only continues to spread if conditions are favorable. Mold can get under wood stains and sealers, causing them to weaken or fail prematurely. Mold will also rot and decay wood if it is neglected, which will jeopardize the integrity of the deck and decrease its longevity.
Black Mold and why it grows in Certain Deck Stains
Exterior deck stains are subjected to the elements, making them prone to natural contaminants. A deck stain is there to shield the wood from harsh weather and the damage it can cause such as rot and decay. In providing protection sometimes the deck stain itself can be compromised.
Black mold is one of the natural occurrences that can affect a wood stain effectiveness and longevity. There are several reasons why black mold can grow on, or in, a deck stain. Here are the most common reasons.
Inexpensive or Cheap Deck Stain
Going with a cheap deck stain may save you money initially but may cost you more in the long run. Cheaper deck stains consist of a lower-grade linseed oil that lacks the mildewcides that help fight black mold.
In some areas, black mold is almost impossible to avoid. Hot and humid climates, or areas next to water, are always more prone to all sorts of mold, mildew, and algae. In this situation, black mold can grow on top of a deck stain and jeopardize the overall appearance.
Tip: In this case, use a deck stain that fights against these contaminants and increases the frequency of deck maintenance to keep black mold from becoming a problem.
