A. How does black mold look like on drywall?
Drywall carries the risk of mold growth because of its porous construction on the inside. Mold on drywall usually starts to appear on the side part.
In the early infestation, the colony of molds looks like random dots or patches in black, green, or grey color. However, they can spread quickly into a larger area and cover most parts of the wall.
Mold can also show up in the bathroom. High level of moisture and humidity is the major reason for rapid mold development. Mold in bathroom drywall commonly appears as muddy and spongy patches.
