Why Painting Over Mold is a Bad Idea


do not paint over mold!

I’ll go ahead and say that you can’t solve mold issues with half-measures. Unfortunately, many folks decide to simply paint over mold in search of a quick fix.

However, painting over mold will only temporarily hide it and it will not solve the problem. Mold is a microorganism that grows on walls and other surfaces and paint can’t eliminate it. Trust us — painting over mold is a bad idea.

It often happens that mold continues to grow beneath the painted surface and eventually eats through it. This is the source of those black and green spots on your walls and patio. The discoloration comes from the chemical reaction between the mold and the surface.

Some people resort to using mold-resistant paint (like Kilz), but this isn’t advised as a standalone solution. If you paint over mold with Kilz, the mold does not die.

Take Extra Precautions

According to CDC, being exposed to mold can cause irritation of the eyes, nose, and throat, it can trigger severe allergic reactions, and even cause serious health issues in people with compromised immunity.

That’s why it’s extremely important to identify the problem and get rid of it before you start painting.

How to Eliminate Mold From Your Walls

If you choose to handle mold infestation by yourself, there are various products available and their effectiveness will depend on the type of mold you’re dealing with. Types of mold differ according to their color, which ranges from grey and green to brown and black.

You can quickly eliminate some strains of mold. However, others require you to put in additional effort.

Vinegar and bleach are top choices for combating most types of mold. In 95% of cases, it will solve the issue you’re having. However, it sometimes fails to kill all of the mold, leaving you reaching for another approach.

You may also consider commercial mold cleaners and removers. Yes, there are various types of products designed specifically to target mold. They’re created using different ingredients, including bleach, ammonia, or mold-eating enzymes.

Different products may work best against different kinds of mold, which is why identifying which type of mold infested your home is of key importance. To do that you’ll need professional help.

A professional mold team will determine the extent of damage caused by mold and recommend the necessary repairs. Improper treatment of mold often makes the problem worse.

Preventing Future Infestations of Mold

Once you’ve cleared your home from mold, you’ll want to make sure that it doesn’t appear again.

It’s important to keep your home dry and well-ventilated. Also, any previous sources of leakage should be thoroughly cleaned and dried.

Another thing you can do before painting is to use a mold-resistant primer. This is particularly beneficial for rooms where air humidity is high, such as the kitchen or the bathroom.

Certain buildings and walls are more susceptible to mold than others. This is due to their structure and the weather conditions typical for that region. In such cases, dehumidifiers can keep the levels of air humidity low and keep mold at bay.
