Painting with Mold-Resistant Paint: Answers to All Your Most Pressing Questions
How Should Homeowners Choose a Mold-Resistant Paint
You can often stop a mold issue before it starts just by choosing and applying the right paints.
Mold-resistant paints contain antimicrobial agents. These active ingredients defend surfaces from microbial growth. In doing so, they fend off the spread of unpleasant odors and visuals caused by mold. Unfortunately, these agents lose their effectiveness within a few years. It may be necessary for you to continuously reapply your mold-resistant coatings.
Many manufacturers claim that their mold-resistant paints are 100% water-resistant. Since moisture is a key element in creating mold and mildew, it makes sense to choose a water-resistant coating. Does waterproof paint really work?
The short answer is yes; waterproof paints can and do work. However, most products can only withstand a limited amount of water pressure.
As such, it’s essential to repair any leaks or ventilation issues before applying waterproof paint.
Expect that your waterproof paint will do little more than create a moisture-resistant barrier. In essence, it should protect moisture, like condensation from a hot shower, from penetrating drywall boards. With that said, it should not be expected to hold water back. As trapped water can only worsen the spread of potentially health-threatening molds and mildews.
Calculate the amount of paint you need to cover all of your target areas. Most mold-resistant coatings do not offer safe coverage as standard surface paints. There paints offer more similar to primers, which are said to cover anywhere from 225 to 275 square feet of coverage per gallon.
Paint drying times vary dramatically between products. Typically speaking, latex- and water-based paints dry much faster than oil-based ones. Paints may feel dry to the touch in just a few hours. Even so, homeowners should wait even longer before applying an additional coat. Moreover, it typically takes weeks before paint is fully cured. Check your paint’s label for exact drying times.
Most mold-resistant paints serve as either self-priming paints or primers. When a building surface is exposed to mold or mildew, it’s important to apply a protective primer as well as a topcoat.
Primer helps hide imperfections while increasing the durability and resistance of the surface below.
Self-priming paints are like to two can of paint in one. Be wary of complaints that indicate a need for several layers of self primer.
Paints may have oil, water, latex bases. Which base does a better job of resisting mold? If you ask a seasoned contractor, they’ll tell you that oil paints are the gold standard for outdoor projects. On the other hand, latex is naturally mold and mildew resistant. Not to mention, it contains less VOC, meaning it’s the healthier option.
Up until recent times, water-based paints didn’t get the attention they deserve. According to Bob Vila, these paints dry rapidly and are easier to clean. Since oil-based paints are more susceptible to mildew and mold, water-based paints are gaining popularity as outdoor paints.
Paints come in several different finishes, including:
- Matte or Flat
Most home improvement experts recommend that matte paints only be used in low-traffic, low-moisture areas. So reserve flat paint for living room walls and ceilings. Eggshell and satin finishes are a bit glossier. The application of these paints should be limited to indoor areas with low to no moisture.
Can I paint over the existing mold?
Some manufacturers tout the fact that their paint can be spread directly over the existing mold. That being said, painters always get superior results when they take the time to prep their painting surface before hitting it with a brush. You can use a nylon brush and a diluted mixture of bleach and water to eliminate any surface fungi.
Where are the best places to use mold-resistant paint?
Mold-resistant may be suitable for indoor or outdoor surfaces. These paints are intended to be used in rooms with enhanced moisture, such as bathrooms, laundry rooms, kitchens, and basements. There are also mold-resistant coatings that are compatible with specific surface materials, such as masonry, drywall, wood, and metal.
What are EPA-approved fungicides and mildewcides?
The EPA, or the United States Environment Protection Agency, approves the limited and controlled use of some fungicides and mildewicides. EPA-registered antimicrobial agents are proven to kill existing mold, mildew, moss, fungi, and odor-causing bacteria. Some strict environmental regulations come along with these potentially harmful chemicals.
Is mold-resistant paint a cure all for my home moisture issues?
You need to address the principal cause of mold you’re looking to tackle before applying mold-resistant paint. You may even opt to call a professional mold expert. They will help you pinpoint and eliminate moisture issues. Sometimes the issues run deeper than the surface. To put it harshly, mold isn’t something you can wish away.
Of course, you can also use mold-resistant paint as a preventative measure, applying it to inevitably high-moisture areas, like bathroom ceilings, basement walls, and kitchen backdrops. Most paints eliminate mold growth for anywhere from 5 to 10 years.
Most homeowners will have to tackle mold at one point or another. They must know how to mitigate these issues to protect their family members and roommates. In addition to causing overwhelming structural issues, mold is associated with a long list of respiratory and other health issues.
Mold-resistant paint can be applied to floor, walls, and other surfaces to stop the spread of or even kill potentially harmful microbes. Mold is unsightly, smelly, and irritating. With the right products in your arsenal, you can restore high-moisture areas to their original quality.
