What Do Black Molds Look Like On Wood?

You can identify black molds by looking at their colors, shapes, textures, and odors. However, you must be aware of precisely what they look like because they can be dangerous at times. To further explain that, listed here are some characteristics of black molds.



During the early stages of black mold growth, you will notice fuzzy white fibers that look like cotton balls. As it starts to produce spores, it turns green or gray with white color around its edges. Lastly, when the spores become filled in and the mold matures, it turns black or greenish-black.



When looking for black molds, thoroughly inspect because it can sometimes be tricky due to wood patches and patterns. Black molds can often grow into circular patterns or dark, irregular patterns.



The texture of black molds may depend if they are still wet or not. When the black mold is still in moist areas, it may look shiny or slimy. On the other hand, black molds will be powdery and dry when water leaks and damages become fixed.



One more way to find black molds is by identifying if there are foul odors nearby. Since they grow in moist areas, some black molds may smell musty or earthy, and some may resemble the odor of rotten wood or wet socks.


What Are The Possible Causes Of Black Mold?

Water damages are the primary reason for black mold growth on wood. It can be due to flooding, poor ventilation, humidifiers, irregular maintenance, damp cloths, or other factors that may lead to water leaks. Anything moist and wet can be a breeding place for black molds.

Aside from the possible roots of black molds, knowing how long before wood gets damaged from water is also crucial. When wood becomes ruined by water leaks, the appearance of black molds will begin. It can usually take 2 hours to 7 days for mildew growth.


What Should You Do If You See Black Mold?

Upon seeing black molds on wood, it is better to get rid of them immediately. To help you do that, you can follow these steps:

Black molds can lead to allergic reactions and respiratory infections, so we recommend wearing protective gear to prevent these health issues. Protective gear may include safety goggles, rubber gloves, facemasks, and overalls.


Step #3. Spray the area

Spray the surface of the black molds with the cleaning solution until it gets saturated. After that, let it sit for 5 to 10 minutes.
