What Is White Mold?: Mold vs. Efflorescence

If you know you have some type of mold problem in your home, but have not yet received a specific diagnosis, you probably have a number of questions. The most prominent question in your mind might be about the type of mold that you see. You may naturally perceive mold as being white in color or may have heard that white mold is very common in households. Naturally, the first question that pops into your head is “what is white mold?what is white mold?

While white mold is common, you have probably heard more about black mold because there are certain types of black mold that are more hazardous to your health. The tricky part is that molds color does not necessarily determine its level of severity. For instance, black mold is considered so dangerous because Stachybotrys is a toxic mold that happens to be black. However, some other types of mold that are black are not very dangerous at all. In the same way, the risk of white mold growth certainly varies with the specific type of white mold you have and it is very difficult to identify the species without consulting a professional.

An additional problem that arises with the identification of white mold is that it looks nearly identical to efflorescence. Efflorescence is a miniscule crystalline structure that is left behind on brick and cementitious materials or rock after water moves through it. Efflorescence is a calcium salt and is completely harmless, but often causes concern because it gets confused for white mold.

Due to this common misunderstanding between white mold and efflorescence,it’s important to be able to tell the difference between the two. Compared to efflorescence, what is white mold? One distinctive element of efflorescence is that it is only found on concrete or masonry structures. Because of this, if you find anything that looks like white mold on any other materials, you can be sure that it is not efflorescence and it is most likely white mold.

Another test is to apply a water mist to the substance. Efflorescence usually dissolves under mist while white mold does not. Finally, you might be able to determine white mold by its smell. While mold does not always emit an odor, efflorescence never does. So, if you can smell it, chances are, it is mold.
