Mold and Mildew Resistant Paint Finish Options

Mold and mildew-resistant paints are available in different types of finishes. Let’s take a look at the options available and their ideal surfaces:

Matte (Flat)

  • Price: 4/5
  • Usability: 3/5

With zero to 10 percent gloss, a matte (or flat) finish offers no reflectivity of light. This makes it unsuitable for places that receive little natural light. It’s more suited, instead, for hiding imperfections such as cracks and patches.

Being the least durable of all finishes, it’s also difficult to clean (1). Therefore, it works well on areas such as ceilings since no one touches the ceiling.

We’d recommend it for homes without young children or pets. It’s also not the best paint for the toilet or bathroom because of its low water resistance.

Pros

  • It hides imperfections and cracks.
  • It’s an excellent option for living spaces.
  • It’s suitable for ceilings.
  • It provides a clean and non-reflective finish.

Cons

  • It’s not as durable in high-traffic areas.
  • It’s difficult to clean, which makes it an unsuitable option for homes with children and pets.
  • It doesn’t have good water resistance.

Eggshell

  • Price: 4/5
  • Usability: 4/5

Like matte, eggshell has a low reflective sheen with a 10 to 25 percent gloss composition. We recommend it for rustic-style walls or for adding a vintage touch to wooden furniture.

Due to the sheen, you might love that it makes a room look a little bigger than it actually is.

It’s also slightly more durable and provides more protection than matte. It’s easier to clean as well. One drawback is that it can make cracks or imperfections more noticeable.

Pros

  • It has a subtle glossy finish.
  • It can help make a home look more vintage.
  • It can make a room look bigger.
  • It’s more durable and water resistant.
  • It’s pretty easy to clean.

Cons

  • It can highlight cracks and imperfections.
  • It’s hard to touch up and paint over parts as this will add more gloss.

Satin

  • Price: 3/5
  • Usability: 4/5

Often categorized alongside eggshell because of its slight luster, satin offers more durability and features about 25 to 35 percent gloss.

Since it’s more durable and easier to clean, it sort of fits into the role of middle ground. It offers just a slight gloss. But at the same time, it provides the same uses as eggshell or matte finishes.

Satin paint works well in high-traffic rooms and can even be used outdoors. However, it doesn’t hide imperfections as well as matte or eggshell.

Pros

  • It has a noticeable gloss which some people love.
  • It’s very durable.
  • It’s easy to clean.
  • You can use it in pretty much any room of the house, including outdoors.

Cons

  • It might be more expensive and harder to find.
  • It doesn’t hide imperfections well.

Low or Semi-Gloss

  • Price: 3/5
  • Usability: 4/5

This popular coat is suitable for rooms with high and low moisture levels. With 35 to 70 percent gloss, it offers drastically more light reflectivity than satin. However, because of its high reflectivity, it cannot hide imperfections on the wall.

It’s very durable, making it ideal for rooms with lots of activity and traffic. You can use it both indoors and outdoors. As it’s very easy to clean, you can use satin paint in the bathroom, toilet, and kitchen.

Pros

  • Great for kitchens and bathrooms since it’s moisture resistant.
  • Semi-glossy, giving it a lovely sheen.
  • Very durable, making it great for homes with kids and pets.
  • Suitable for indoor and outdoor use.
  • You can clean it easily.

Cons

  • It doesn’t hide imperfections or cracks at all.
  • It’s a bit harder to apply.
  • You will need to do three coats sometimes.

High Gloss

  • Price: 3/5
  • Usability: 3/5

With 70 to 100 percent gloss, high gloss is the most durable and reflective coat.

It’s the easiest to clean, and you can apply it anywhere, including in high-traffic areas. High gloss paint is perfect for door trims, woodwork, molding, cabinets, kitchens, bathrooms, and even outdoors.

With zero imperfection-hiding qualities, however, it would be difficult to apply by oneself. So, we’d recommend using a professional.

Pros

  • It’s very durable, making it ideal for busy homes.
  • It’s super easy to clean.
  • You can apply it anywhere, including indoors and outdoors.
  • Gives a lacquer finish but is cheaper than lacquer.

Cons

  • It’s a bit more expensive than other kinds of paint.
  • You will need a professional painter to apply it.
  • It can take six to seven strokes to apply it evenly.
  • It doesn’t hide imperfections or cracks on your wall.

Selecting the Best Mold and Mildew Resistant Paints

We have come up with a list of features to check for when choosing mold and mildew-resistant paints. That way, you can make a decision that suits your needs.

Guaranteed Duration

How long will it last? This is the first question that should come to mind when making a choice. To be cost-effective, it’s best to get a product that is guaranteed to last for a while.

The endurance of the paint itself and the effectiveness of its resistance to mold and mildew differ significantly. More often than not, the paint outlasts its ability to protect your walls from mold and mildew.

This means you might still have a decent wall of paint, but it will no longer be resistant to mold. Pay special attention to this particular detail so you know when you might have to repaint.

Coverage Area

Knowing how many square feet a particular product can cover per gallon helps greatly — the more, the better.

This figure determines how much of an area you can paint with what you have. So, for example, paint with a coverage area of 400 square feet per gallon would be preferable to one that covers 250 square feet per gallon. This can vary depending on how porous the surface is.

Ultimately, knowing the coverage area helps you know how much paint to purchase.

Base

This refers to the type of solvent used in the paint. It is the liquid component of the paint that evaporates when the paint dries.

1. Oil-Based

This type of paint uses an organic solvent made up of petrochemicals and plants. It becomes a volatile organic compound (VOC) when it evaporates into the air. This vapor can be harmful to your health (2).

Therefore, when applying, ensure that there is good ventilation. Oil-based paints have a high sheen level, which is lost over time. Although they possess less flexibility, they are resistant to wear and tear.

2. Water-Based

Also known as acrylic paint, water-based paints are made up of mostly water. They release considerably fewer VOCs into the air. They’re also considered better for the environment and general health.

While water-based paint has a lower sheen finish, it lasts longer over time. They also possess flexibility that prevents them from cracking (3).

We recommend water-based paints because of their eco-friendliness.

Waterproof

A mold and mildew-resistant paint should be either water-resistant or waterproof. This refers to how much moisture exposure it can sustain.

This property protects against excessive moisture and prevents damage that can lead to costly repairs. If moisture gets into the surface, mildew or mold can build up, causing ugly stains and creating potential health issues.

Waterproof paint is ideal for bathrooms or parts of the house with high moisture levels because it prevents moisture from seeping into the walls.

Self Priming

When a surface isn’t water-resistant and will be exposed to the elements, priming is compulsory before painting. Priming helps provide better adhesion to a surface. It enhances durability and provides extra protection for the painted material.

Take Note

Some mold and mildew-resistant paints are self-priming. This means prior priming isn’t required. Essentially, it seals the surface by itself. Self-priming paints are designed to perform the role of both the paint and primer. This helps save time and money.

FAQs

How Do You Get Rid of Mold on Walls Permanently?

The best way to get rid of mold on walls permanently is to use one part of hydrogen peroxide and two parts of water. Spray it onto the wall, wait 20 minutes, and then rub the mold away with a cloth. Keep repeating this process until the mold is gone.

How Do You Stop Mold Growth on Bathroom Walls?

The best way to stop mold growth on bathroom walls is to keep moisture to a minimum. Always open windows or run extraction fans to remove the wet air, and always dry the walls with a clean cloth.

Another idea is to paint the bathroom walls with mold-resistant paint, like this KILZ Basement and Masonry Paint. It contains mold-killing ingredients that stop fungal growth.

Does Mold-Resistant Paint Really Work?

Mold-resistant paint absolutely works! It contains antimicrobials that are safe for us but deadly to mold and mildew.

What Can be Added to Paint to Prevent Mold?

You can add lime to paint to prevent mold. The pH value of lime juice is a natural mold inhibitor. The other thing you could do is create your own milk paint. Milk neutralizes mold, causing it to die.

What Happens When You Paint Over Mold?

When you paint over mold, it doesn’t kill the spores but gives them a sheltered and dark environment in which to breed. The mold always comes back, ruining your fresh paint.
