Best Paint to Use to Prevent Mold in Bathrooms

Painting the bathroom presents certain concerns that you don’t necessarily need to worry about in other rooms of your home. Of course, mold is a huge issue in many bathrooms, simply due to the nature of bathrooms; steam from showers and baths can seep into walls and cause mold (and we all know what mold can do to a home). Short of tiling your entire bathroom—something that not everyone wants to do—is there anything you can do to mitigate and prevent mold from forming?   Yes! We have a few suggestions that are highly effective:

What Kind of Paint Should You Use?

When you want to paint your bathroom, you’ll need to think about how you can best prevent mold and mildew growth. Hiring an interior painting company can be a lot of help, as they will have access to certain techniques and products that you may not be aware of, such as mildew and mold-resistant paint or paint additives. If you have mildew or mold already, you’ll need to treat for mold first before repainting—simply painting over the existing problem will not solve it; you will eventually have to scrape off paint and deal with the mold.

Ask your contractor what their advice is regarding how to prevent mold. They will be able to offer the best advice. That being said, semi-gloss or high-gloss paint, opposed to flat paint, is more resistant to staining, easier to clean, and creates a harder surface on the wall, which makes it harder for mold to grow.  High gloss, however, is not a popular choice, since many people do not like the way it looks across large areas like an entire wall. Even so, using semi-gloss paint doesn’t mean that mildew or mold will not grow at all—just that it repels moisture better than flat, eggshell, or satin paint and is easier to clean. You will have to be proactive with cleaning, no matter what type of paint you choose.

Other Ways to Prevent Mold

There are a few different ways to prevent mold and mildew growth that have nothing to do with paint.

For instance, if you don’t have an exhaust fan in your bathroom, you need to install one. Keep it running during and after baths and showers, as well as when you clean the bathroom. Anytime there is more moisture in the air than normal, using the exhaust fan can help clear it out so that it doesn’t seep into walls.

If you already have an exhaust fan but it’s not working well enough, install a stronger one that will provide better ventilation. You may also want to install a window with a screen to open to help dry out the room.

Clean your bathroom with a diluted bleach-and-water mixture every now and then to kill germs within the room, as well.

If you’re building a new bathroom, insulate the walls well so that when they are cold, moisture does not condense on them.

Whether you’re renovating your entire bathroom or making smaller updates, you can refresh the look of your bath and prevent mold growth.  Repainting can be the most effective means of accomplishing both. Be sure your paint selection is right for bathrooms or seek the guidance of your interior painter to ensure the right selection for your rooms.
