Before getting deep into mold-resistant paints and what’s best for you, let us first understand mold. 

It is basically a fungus called hyphae that grows on any surface of our house. And it can grow anywhere, whether in the form of fuzzy white spots on the floor, slimy black (mold) spots on the curtain, or slick orange film in drains. 

These molds can be detrimental for your health, especially if you have asthma or allergies. Besides, constant mold exposure can lead to irritation in your skin, eyes, nose, lungs, and throat.  

However, using mold and mildew-resistant paint will help avoid these problems. So, we decided to search the market and shortlist the five best paints that can prevent a mold outbreak in your house. If the plethora of options have left you confused, then you’re at the right place.

So, without further ado, let’s jump in!

What Could’ve Been Better?

What Could’ve Been Better?

Mold Resistant Paint Buying Guide

Mold and mildew-resistant paints contain strong fungicides that destroy molds. These fungi thrive on humidity and will need to be dealt with quickly before it affects your and your family’s health. But you can’t pick any mold-resistant paint at random, which is why we have curated this buyer’s guide with the key factors to keep in mind before buying one. 

  1. Areas Of Application

The rooms most vulnerable to developing mold include toilets, bathrooms, kitchens, laundry rooms, or utility rooms with less or no ventilation. Hence, such paints should be applied to areas where the deposition of water or moisture is very high. 

Aside from that, you may use them for your basement or workshop to get mold-free walls and reduce the chances of mold growth there.

But as all brands do not create similar paints, you need to check the formula before going ahead with a product. We’d also suggest opting for a brand that offers more than two years of warranty on their paints. 

Remember that mold-resistant paint should be applied to dry, clean, and mold-free surfaces. Using it where you already had mold formation can help avoid future problems. But before its application, the surface needs to be cleaned thoroughly. 

However, it might not kill the ones already growing on a surface. So, applying it on such surfaces may, well, be a waste of money. Also, it is to be kept in mind that anti-mold paints do not guarantee mold growth in the future, especially in case of excessive water damage or flooding. 

  1. Durability

The durability of mold-resistant paint determines how long it can protect the walls from mold formation. Naturally, this factor is a significant concern for homeowners. Besides, anti-mold paints are costly, so users need to emphasize this particular aspect. 

Agencies like the EPA conduct checks to test the durability of these paints and whether they will be effective in the longer term. And the results can give you an idea about the expected longevity of the product. So, it will be viable for you to look out for EPA-registered paints. 

Additionally, many paint manufacturers provide guarantees over these products based on their longevity. Such policies basically depict the quality of ingredients being used. The more extended the warranty, the greater the quality, and vice versa. 

  1. Undercoat

There is more to mold-proof paints than just applying them on a surface. It will be much more effective if used as an undercoat, thereby making it serve as a mold-killing primer. Although it might increase the cost, it will provide increased protection against mold and mildew. 

This method is especially recommended for areas most vulnerable to molds, like in a bathroom, where mold spores can create major problems. 

  1. Additives

Instead of purchasing pure mold-resistant paint, some people opt for buying mold-resistant additives and mixing them into ordinary paints. This might seem a cheaper option for many, but you will need to ensure that everything is mixed correctly. 

We’d suggest getting professional help for mixing and painting such products. They have adequate knowledge about the mixture ratios and the right application method. 

  1. Coverage

As stated above, you will need to ensure that the surface is free from any mold and mildew before you start painting. It can turn out to be a time-consuming task, but it is the most crucial step. If you fail to clean the surface, the paint might not deliver desirable results. 

Plus, you will find that mold-resistant paints work better when applied in a thin rather than a thick coat. In some cases, a single coat of paint over the undercoat may seem just perfect, but in other cases, you may need to apply two or three coats for it to be effective. Hence, it’s feasible to buy a paint that provides more coverage.

  1. Cost

Mold and mildew-resistant paints are more expensive than regular ones and are available in various-sized containers. And truth be told, the high prices are inevitable, as it performs a specialized job and uses specific ingredients fit for the purpose. 

That said, you can cut down on your costs by browsing around hardware stores or options to find the best deals. 

  1. Nature Of Paint

A quality anti-mold paint must be alkaline and breathable, free of any organic elements. Hence, paints that contain tempera or other crude oil derivatives need to be discarded. This is because microorganisms will proliferate if the walls have a lower pH level. 

While purchasing an anti-mold paint, it needs to be ensured that it contains ingredients like vinyl resins, transpiring, and antibacterial, antifungal or antimicrobial agents that are water-repellent. 

  1. Application Methods

Once you have selected the best mold-resistant paint, don’t forget to check the application instructions provided by the brand. This will also help you keep the specialized tools handy for the purpose. 

An anti-mold paint is usually applied just like any other paint. Hence, you can use either a roller or brush to apply the coats. 

Now since most paints are white in color, you can add a colorant, but not more than 5%. But before that, make sure to have tools like a paintbrush, masking tape, paint roller, personal protective equipment, and painting sheets.
