How to choose the mold and mildew resistant paints

Choosing the best mold and mildew resistant paint may be a struggle as there are so many products to choose from in the market. However, when deciding, you must always consider picking paints that are specific to your needs and situations. To help you, we have listed a few features to consider when choosing mold and mildew resistant paint.

  1. Guaranteed duration

When picking paints for your home, you should initially think about the duration of the paint. It is critical to check the endurance and strength of the paint to ensure that it will be able to prevent mold and mildew buildup for a long time. Having durable paint will also help you save money and time as you will not have to keep buying and applying more paint onto your walls.

  1. Base

The base is generally the fluid part of the paint that vanishes once the paint is dry. There are two types of paint bases: oil-based paints and water-based paints.

  • Oil-based paints generally have a higher gloss level due to their formulation. However, the disadvantage of this type of paint is that the sheen becomes dull over time.
  • On the contrary, water-based paint produces a lower sheen finish, but these sorts of paints can maintain their sheen level much longer.

Overall, we recommend utilizing water-based paints as they discharge less volatile organic compounds (VOC) than oil-based Paints. Water-based paints have also been discovered to be better for the environment and they are adaptable which forestalls any cracking.

  1. Finish

There are various sorts of paint finishes that you may should consider as this would add to how your home will look eventually.

  • Low or semi-gloss

Low or semi-gloss paints are shiny. They are durable and mildew resistant, so they are utilized in rooms that create more moisture such as kitchens or bathrooms. Because they are glossy paints, they additionally flaunt blemishes on your walls much easier.

  • High gloss

High-gloss finishes are the shiniest kind of paint finish. They are additionally the strongest and easiest to maintain. Prior to using high-gloss paint, you must prep your surface first as these types of finish show off blemishes when applied wrong.

  • Satin

Satin finishes are the most well-known type of indoor paint. These types of paints have a velvety sheen and are simpler to clean than flat or eggshell paints. They are also suitable for areas such as kitchens, playrooms, bathrooms, etc. The lone issue with satin paints is that it flaunts brush strokes on the wall, therefore, any touch-ups on your wall are not recommended.

  • Matte (flat)

Matte paints (also called flat paints) have the least amount of shine. They also provide the most coverage and require fewer coats than other types of paint. However, they are not durable and are usually used in areas such as dining rooms.

  • Eggshell

Eggshell finishes are well known as they are somewhat more radiant than flat paints, and they have good coverage. They are sturdier than flat finishes and are appropriate for places such as living rooms, entryways, and hallways.

  1. Water-resistance

Because mold and mildew generally form in areas that are prone to moisture, it is important that you choose paints that are water-resistant to prevent any mold or mildew from ever-growing on your walls. Having waterproof paints for your bathrooms or kitchens is recommended as these are the areas that generate the most moisture.

  1. Priming

Priming may not seem significant, but paint primer helps form a steady surface that your paint would stick itself to. It gives protection and hides any surface stains. To save both time and money, we suggest purchasing a mold and mildew resistant paint that can prime itself. Using a primer and paint in one is as effective and less time-consuming than separately priming your walls.

  1. Coverage area

Knowing the coverage area of the paint you pick is important as this would help you calculate how much paint you need. Accordingly, you should check how many square feet a specific item can paint per gallon.

  1. Anti-microbial properties

Because you are attempting to forestall the development of any mold or mildew on your walls, you should consider purchasing a paint product that has anti-microbial properties. This helps kill or moderate the increase of microorganisms such as mold or mildew.

  1. Drying time

Paint drying time can vary according to brands or types of paint. Some paints dry to touch within 30 minutes, while there are some that may take 72 hours to dry totally. It is essential to check the dry time of the paint you are purchasing so that you will know how long you need to wait prior to applying a second coat or a topcoat.

Frequently Asked Questions

Can I paint over the existing mold?

The paint itself does not kill mold, so simply covering up existing mold will not eliminate it. If you want the paint to cover mold, we suggest using KILZ products as this is an anti-mold paint. However, make sure to spray the area with a bleach and water mixture prior to painting.

What are EPA-approved fungicides and mildewcides?

The term “EPA-approved” means that a product that should not pose any danger to your wellbeing. Therefore, an EPA-approved fungicide is a pesticide that is safe for you and it prevents the formation of fungi, while an EPA-approved mildewcide is an agent that is not hazardous and will diminish mildew.

Is mold-resistant paint toxic?

Mold-resistant Paint is like any other paint; however, it has anti-microbial properties that diminish the further development of mold. While normal paint can be entered by mold, Mold-Resistant Paint will act as an obstruction and will prevent mold from growing. However, you must remember that it is just a barrier and will not eliminate the mold from your walls.

How long does mold-resistant paint last?

Mold-Resistant Paints last for different periods according to brands. However, the widely recognized period is from 4 to 6 years. For your mold-resistant paint to last long, you should ensure that your surfaces are thoroughly sterilized, cleaned, and dried prior to the application of the Mold-Resistant Paint. We also recommend using a primer, sealant, and a paint guard to increase the lifespan of your mold-resistant paint.

Where can I use mold-resistant paint?

Areas that are inclined to the development of mold and mildew such as bathrooms and kitchens are the places where mold-resistant paint is most suggested. This is because these areas generate the most moisture. Kitchens produce steam from cooking, while bathrooms generate steam from showers. This generated moisture can add to the development of mold. 

What is better between mold-resistant paint vs mold-killing paint?

Mold-resistant paint has anti-microbial properties that give protection to the painted surface. These properties keep mold from entering by acting as an obstruction. It will not dispose of existing mold; however, it will decrease the chances of new mold growth. Be that as it may, Mold killing paint is a fungicidal protective coating that is utilized to cover and kill mold. It additionally contains an anti-microbial that forestalls the increase of mold. Mold-resistant paint will be safer because it simply inhibits mold growth. However, mold-killing paint contains pesticides which are an effective method of removing mold from your walls.
