The short answer is: no. You should never, in any circumstance, paint over mold. This is a huge mistake made by both homeowners and landlords every day when it comes to “fixing” a mold problem. Unfortunately, painting over mold does no good. In fact, it can lead to more costly repairs, negative health conditions, and even legal trouble.

Why You Can’t Paint Over Mold

Mold itself is a problem that is reflective of an even larger problem. For instance, mold in your home is nearly always indicative of a moisture problem. Whether that problem is a leak, a window left open in the rain, or improper ventilation, it needs to be addressed. Mold is a signal telling you that there is a larger problem in your home. Covering it up with a coat of paint does nothing to fix the mold nor the original problem. The mold will continue growing and the original problem will persist, possibly resulting in costlier and even dangerous damage to your home or property.

Does Mold Proof Paint Work?

Yep! Mold proof paint does an excellent job of repelling mold from growing on your walls. If you are painting new walls or mold-free walls, it is a great option that can save you headache down the road. Unfortunately, it doesn’t work if there is already mold on your walls.

Does Mold Proof Paint Kill Mold?

Unfortunately, it isn’t that easy. Painting over existing mold with mold proof paint is just as ineffective as painting over it with regular paint. The mold underneath will neither die or stop growing unless it is properly treated. Putting mold proof paint on after you already have mold on the wall is like putting your seatbelt on after you’ve already been in a car crash.

Why Is Painting Over Mold Bad?

There are actually several reasons why painting over mold is a bad idea. Here are just a few:

Temporary/Ignorant Fix

Simply painting over mold is the same as turning a blind eye to it. The mold will remain and will keep growing and causing problems in your home. It will eventually grow through the paint and spread further.

Costlier repairs

When a home repair project gets worse, the cost to fix it goes up. Since painting over mold simply lets the mold and its cause make the problem worse, you’ll end up with a costly repair project rather than a simple mold cleaning.

Legal trouble

If you are a landlord or are trying to sell a home that has a mold problem, painting over it can land you in hot water legally. Should the tenant or buyer experience health problems from mold exposure or have to spend a large amount of money to repair it, they could sue you for it. Even if you win, you’ll have costly legal bills to pay. If you lose, it could be even worse.

How Should I Get Rid Of The Mold?

Rather than painting over it, use a solution of 1 part bleach to 10 parts water and wipe the mold away. If it is on a smooth surface, this is all you’ll need to do. If it is on a rough surface like concrete or porous surface like wood, you may need to call in a professional mold remover to take care of the problem since that mold will be much harder to remove.

When Should I Use Mold Proof Paint?

After, and only after, you have removed all mold from the wall. Then, use a few coats of mold proof paint to ensure you won’t have to deal with the problem again in the future.
