Does Mold-Resistant Paint Really Work?
Mold-resistant paint helps to stop mold from spreading thanks to its antimicrobial qualities. Mold loves damp and dark spaces. Any area of your home that has poor ventilation, and a combination of humidity and heat, will take hold and grow.
Mold-resistant paint kills mold spores and slows the spread of the nasty black fungus. However, it will not entirely banish mold and mildew. Over time, they slowly start to grow back.
Types of Mold-Resistant Paint
Choice is a wonderful thing, but unless you know which mildew-resistant paint works for you, how do you decide? Here are some pointers:
Matte
Matte paint has no reflective qualities. It has between 0 and 10 percent gloss, and it dries flat, so if you have a room that gets almost no natural light, you might want to consider a gloss finish.
Matte is better for low impact, drier areas of the house like ceilings and high walls. And because it is a matte finish, it isn’t as robust as other types and harder to clean. You can use it in bedrooms and living spaces, as well as kid’s bedrooms.
You might get away with using matte paint when painting bathroom ceiling, but that’s about it for water resistance.
Eggshell
Eggshell has many of the same qualities as matte paint. The gloss quantities are slightly higher at 10 to 25 percent but still dries with a soft reflective sheen. It is more durable than flat paint, but it is still better for areas with low moisture content.
It’s also easier to clean because there is slightly more of a sheen.
Satin
Satin paint has a slightly more vibrant luster than eggshell, with about 20 to 35 percent gloss. It is more hard-wearing than eggshell, but there is very little to differentiate the finish.
Satin is a good middle-ground option, with better cleaning qualities without the high gloss sheen. You can use satin paint in high-traffic areas, but don’t expect it to hide imperfections and blemishes like matte and eggshell.
Low or Semi-Gloss
This is a popular choice among homeowners because it is used in high-traffic and moisture-rich rooms like kitchens and bathrooms. Thanks to its 35 to 70 percent gloss content, it reflects light to brighten up low light areas. It can also be used in indoor and outdoor situations, and it is easy to clean.
High Gloss
With a gloss content of 70 to 100 percent, high gloss paint is the most hard-wearing and reflective of all the paint options. It reflects light in low-light rooms and is super easy to clean.
You can apply it to just about anywhere and to any surface. You can use it on window frames, door trims, woodwork, and moldings.
How To Choose the Best Mold Resistant Paint
What are the key things you should be looking for when shopping for mold-resistant paint? Here’s a rundown of the key considerations before you commit to a purchase.
Paint Durability
Once it’s down, how long will it stay down between fresh coats? The mold and mildew repelling features of the paint probably won’t last as long as the paint will stay looking good, but at least you still get a nice-looking coat of paint.
Of course, if you want to boost the moisture resistance, you could always paint on a fresh layer.
Paint Coverage
How far will the paint spread? Most cans of paint come in 1-gallon tins, so the amount of coverage you get is important to determine your costs.
You can expect anywhere between 250 and 400 square feet, depending on the quality and porosity of the surface.
Oil-Based vs. Water-Based
The formula of the paint makes a difference in coverage, cost, and drying times.
Oil-Based
Oil-based paints are made up of solvents and other chemical compounds that evaporate when they dry. This gives off VOCs (volatile organic compounds), which can be harmful to your health.
Oil-based paints are also damaging to the environment because when you wash your brushes or roller clean, the solvents drain into the water system, poisoning the planet. However, oil-based paints have greater resistance to wear and tear.
You also get a higher sheen, although this does fade over time.
Water-Based
Water-based paints consist mainly of water, so they have a lower environmental impact and fewer VOCs. It means that there are lower health risks because you don’t have to breathe in vapors as the paint dries.
These paints are often referred to as acrylic paints, and they last longer because they have a lower sheen. They also offer more flexibility when they dry, reducing cracks.
Water Resistance
Mold and mildew-resistant paint should repel water because it is the primary food source that causes black mold spores to grow. You need the paint to have that special resilience, otherwise, it would just be ordinary paint.
Higher gloss paint has the best waterproofing because the sheen has more luster, meaning the water beads on the surface, ready to be wiped dry.

FAQs
Can I Paint Over the Existing Mold?
The simple answer is no; you cannot paint over existing mold. It keeps growing under the paint, and eventually, it breaks through the surface.
How Do You Get Rid of Mold Before Painting?
Mix up a solution of 2 parts bleach to 10 parts of water and fill a spray bottle. Apply it to the surface of the mold and let it sit for 10 minutes. Then, wipe it clean with a dry cloth. Repeat as necessary until the mold is gone.
Where Are the Best Places To Use Mold-Resistant Paint?
The best places to use mold-resistant paint are the bathroom and the kitchen. They have the highest moisture content of any room in the house.
How Long Does Mold Resistant Paint Last?
Most mold-resistant paint will give you up to 6 years of protection. It depends on where the paint is applied and the conditions that allow mold to grow. If you have a damp environment, you might find your resistance to mold reduced to no more than 2 or 3 years.
