Yes, mold can grow on plaster. Just like other types of building materials, plaster that has been painted, is dirty, or has been damaged is prime for mold growth. If you find mold growth on your plaster walls, what can you do about it? Read on to learn about mold remediation and prevention for plaster walls.
Mold does not grow on plaster because plaster is non-porous and lime-based or clay. Although plaster does not support microbial growth, if porous cellulose-based material such as drywall is used on the backside of the plaster for support, mold can grow on the drywall.
Drywall provides little to no support to the structure. It is less fire-resistant and mold-resistant than plaster.
Mix a solution of one part bleach and four parts water. Take a cloth and wipe this solution across the wall, scrubbing gently until all the mould has been removed. You can then wipe the bleach away and dry the area using a separate cloth.
Clorox Tilex Mold and Mildew Remover
The Clorox Plus Tilex Mold & Mildew Remover is the best mold remover overall—and it's expert-approved.
This involves applying a waterproof, liquid-applied tanking material to the wall surfaces so as to create an impermeable barrier that prevents water and moisture from penetrating. This will help to protect the plaster and walls from further damage due to mould, dampness and rot.
Hydrogen peroxide, commonly used to disinfect wounds, is active against a wide variety of micro-organisms including mold. It acts by releasing oxygen at a rapid rate, which kills mold by oxidizing the surface and breaking down proteins and DNA.
Zinsser Mould Killer and Remover effectively removes stains caused by mould, fungus and algae. It is ideal for use in bathrooms, kitchens and areas of high humidity and can be used on internal surfaces such as tiles, wood, plaster and wallpaper.
For a natural solution to getting rid of black mold, combine one part baking soda with five parts distilled white vinegar and five parts water in a spray bottle. Alternatively, you can use a chemical-based mold and mildew remover, all-purpose cleaners, bleach or dish soap.
There are commercial mold release agents available, but people often use Vaseline, liquid hand soap, Pam Cooking Spray, Crisco, Vegetable Oil, liquid soap, or Murphy's Oil Soap. Vaseline is thick and stiff, and thus tends to leave brush marks behind.
You can purchase a moisture reading device and check if a particular area has moisture. If there is moisture, then it's more than likely there's going to be mold. When you find the wettest area, cut open 6 “ by 6 “ and then use a bright flashlight to inspect if there is growth.
Unfortunately, there wasn't a regulated or realistic way to ensure that all older buildings using plaster walls were asbestos-free. Asbestos was commonly added to plaster until the late 1980s, as it was seen as an inexpensive way to add to the plaster's insulation and fire-retardant properties.
The only effective way to permanently get rid of mould problems is by reducing the build-up of moisture in your home. This can only be achieved through better ventilation.
The plaster will take anywhere between 3 hours and 3 days to fully cure, but it's typically dry enough to remove from the mould in 30min-1hr. It's a good idea to let it finish setting outside of the mould to speed up the process.
Black Mould on walls (Stachybotrys chartarum, Aspergillus niger or others) is often a sign of a serious problem in your home that needs to be thoroughly investigated. It is often caused by excess condensation, usually as a result of a lack of ventilation in the home that results in high humidity levels.
According to the CDC, people usually experience their first symptoms within 2 to 9 hours of their first exposure. On the other hand, some people could go for weeks or months before feeling sick if their exposure is limited enough. This is why it is also important to check damp, dark areas of your home for mold.
Allergies, Irritations, or Respiratory Problems
One of the first (and most alarming) signs that your home has poor air quality is if you or your family experience an increase in allergies, irritations, or respiratory problems. These sudden changes can be caused by a variety of air contaminants, such as: Mold spores.
The cough is typically dry and non-productive, meaning it doesn't bring up mucus. It is sometimes described as having a "barking" or "hacking" sound.

Thus, exposure to the toxicity of black mold can cause harm to our physical health. Cleaning it yourself risks a greatly increased chance of acquiring damaging health conditions by unsettling the toxins into the air. Depending on the frequency of mold exposure, an individual's health can be severely compromised.
Equipment Used in Mold Remediation
Air scrubbers play a crucial role and filter out mold spores from the air, ensuring a cleaner environment. HEPA vacuums are also vital, adeptly removing mold particles from surfaces. To detect hidden mold, we use moisture meters, pinpointing damp areas prone to mold growth.
Is bleach or vinegar better to kill mold? Vinegar is better at killing mold because it can work on both porous and nonporous surfaces. It also terminates molds at their roots so the mold won't return and is also safer than bleach.
Vinegar is natural and safe mild acid that can kill 82% of mold species. Plus it doesn't give off dangerous fumes like bleach. If you want to use vinegar to prevent mold growth on surfaces, spray vinegar on the surface and leave it. Repeat every few days to keep the surface mold-free.
