Mold and Mildew Resistant Paint Finish Options
Mold and mildew resistant paints are available in different types of finishes. While they all look attractive in their own way, they also have varying characteristics best suited for different surfaces. This determines where they would be most effective.
Let’s take a look at the options available and their ideal surfaces:
Matte (Flat)
With 0–10 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, matte coats are suitable for dry areas of the house with low traffic. As such, it works well on areas such as ceilings, since no one touches the ceiling.
It can be used for bedrooms, living rooms and dining rooms as well. However, 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.
Eggshell
Like matte, eggshell has a low reflective sheen with a 10–25 percent gloss composition. Use it for rustic-style walls or adding a vintage touch to wooden furniture.
It’s also slightly more durable and provides more protection than matte. It’s easier to clean as well.
Satin
Often categorized alongside eggshell because of its slight luster, satin offers more durability and features about 25–35 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.
Low or Semi-Gloss
This is a popular coat suitable for rooms with both high and low moisture levels. With 35–70 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. It can be used both indoors and outdoors. As it’s very easy to clean, satin paint can be used in the bathroom, toilet and kitchen.
High Gloss
With 70–100 percent gloss, high gloss is the most durable and reflective coat out there.
It’s the easiest to clean and can be applied just about anywhere, including 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.
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 greatly. 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 a great deal — 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, though, 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. When it evaporates into the air, it becomes a volatile organic compound (VOC). This vapor can be harmful to your health (2).
Therefore, when applying, it’s recommended to ensure that there is good ventilation. Oil-based paints have a high sheen level, but lose this over time. Although they possess less flexibility, they are quite 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, then mildew or mold can build up, causing ugly stains and creating potential health issues as well.
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.
