Painting over Mold: A complete guide by Painters in Austin

Can you paint over Mold?

Painting over Mold has never been easier- with Painters in Austin

Can you paint over mold? Is that a viable way to kill the mold infestation or will it only make things worse? Are there different kinds of paints and different painting techniques that are more or less effective against mold? We at Painters in Austin are here to walk you through the entire process including application and clean-up, so keep reading to find out!

Painting over mold will only work on a permanent basis if you fix the source of the mold problem first. In addition, you need to purchase a mold killing paint rather than the resistant variety as this is the only way to deal with already existing mold. A mold inhibitor paint helps in preventing the future development of mold, but it isn’t the best option to completely eliminate mold. 

Which isn’t to say that you shouldn’t consider mold inhibitor paint – if your home or room is prone to developing mold then this is exactly the paint you should look for. There are a lot of great kinds of mold inhibitor paint on the market, so go over them carefully. Before applying the paint itself, however, take care of the mold with other means.

If you’ve chosen to paint over mold or if you suspect that your walls potentially have mold under the paint, you will likely see visible signs in affected areas. The entire wall may or may not be affected, but even a small amount of mold can be a serious problem. Here is what you may see:

  • The paint is bubbled, cracked or chipped.
  • White or light colored paint has turned yellow or taken on a yellow tinge (a sign of water damage)
  • The walls or ceilings are not entirely flat. They bubble and/or bow out which is another sign of water damage.
  • If you see signs of mold, you most likely have water damage on that wall that was not properly remediated in the past. If you suspect mold growth behind the paint in your home, you will need to determine the source of the leak and make plans to properly remediate it. Mold will not simply go away on its own, and it has a laundry list of serious health ailments that it can cause you and your family.

Paint over mold doesn’t permanently fix or hide the problem. If you suspect there is mold underneath your paint due to one of the signs mentioned above, do something about it now before the problem worsens. You must properly get rid of mold before painting. There is no exception. Local hardware and paint stores sell mold killing or mold resistant paint. If you do your research, you will find that these claims oftentimes are not true. If you have mold on your walls, it must be properly removed prior to painting. Otherwise, the mold will keep growing and can actually eat through the paint. If the source of the water leak has not been determined, the mold problem can be exasperated. Surface mold is what you can visibly see, but most of the time, the problem is deeper into your walls.

If you suspect that there is mold growth underneath the paint on your walls or ceilings, you should hire a professional mold remediation company to start an official inspection. They will be able to do an assessment of your home and determine the extent of the mold damage as well as recommend repairs. Mold grows quickly (even under paint) so the extent of the remediation may be more than you think.


While there are sometimes that you can undertake mold remediation yourself, it is often best to hire a professional mold team simply because mold is sneaky and dangerous. If you aren’t properly trained, you could contaminate the rest of your home, make the problem worse or put you and your family at a serious health risk.

If Not To Kill Mold, When Should I Use Mold Resistant Paint?

Mold resistant paint is designed to work in rooms with extra moisture in the air. The kitchen, the bathroom, moist closets, the basement, the attic, and all rooms that have had mold problems before. As we said, the fact that mold resistant paint doesn’t kill the mold, doesn’t mean that it doesn’t work – killing mold is just not what it is made for. You can buy good mold resistant paints from any reputable home improvement store. These paints may not be a guarantee that mold won’t spread in the future, but they certainly help a lot.

Before painting over the surface with a mold resistant paint, make sure that the surface is as clean as possible, that all the mold is either removed or covered with a mold sealant, and that the surface is as dry as possible. One of the few things that are worse than painting over mold is painting over wet mold.
