What are the white fuzz on my brick wall and the white powder on my walls? The white fuzz on your brick wall is often caused by efflorescence, which is a natural process where moisture seeps through the brick and evaporates, leaving behind salt deposits on the surface.

Some people believe that bricks are a mold-proof building item, but this is not the case. Although bricks are not that porous and don't have the organic matter necessary for mold to feed, they can develop mold issues. This is because of other materials that can build up on the brick surfaces.
Black mold, as the name implies, is often dark in color. When searching for black mold, look for circular-shaped spots that are black, dark green or dark brown. Some black mold can also take on shades of orange or have flecks of white within it. Most of the time, black mold has a slightly furry appearance.
Contrary to popular belief, exterior walls are porous, meaning they will absorb moisture over-time. This moisture is then transferred into the property causing high levels of moisture. This process is known as penetrating damp and is one of the most common forms of black mould growth on walls.
Mold is often found on brick because it traps moisture after it rains or there is flooding. Some places to check for mold include the physical structure of your home or patio if they are brick.

Covering mold with paint is a waste of resources because the mold will continue to thrive and grow underneath. Eventually, the paint will bubble and peel off, and the mold will be exposed once again.

Pay attention to the color and consistency: We already talked about black mold above, though it's more accurate to say that Stachybotrys chartarum has a greenish-black hue. Toxic mold can also have a grayish, soot-like texture, or a slimy, wet surface. In some cases, you may even notice furry orange or brown spots.
However, the color black isn't unique to Stachybotrys — people often confuse it with similar-colored molds like Cladosporium, Aspergillus, Alternaria, and Dreeschslera. In earlier stages, black mold may appear more greenish-grey or greenish-black in color with fuzzy white edges.
In short, yes. Exposure to black mold can be harmful in the long term, particularly in people with respiratory conditions and other risk factors. Black mold can be one of several different species of fungus, including Stachybotrys chartarum.
Most mold is unmistakable, but sometimes small or largely hidden growths just make a surface look dirty. A quick test for mold can be done when you dip a swab in diluted bleach (1 part bleach, 16 parts water) and dab it on the wall. If the spot quickly lightens (or keeps coming back after cleaning), assume it's mold.
