Does Mold Killing Primer Really Work?

Yeah, in most cases Mold resistant paint or primer destroys mold. But from my own experience, I saw that this would not be true in all cases.

It is because no mold or bacteria will be visible within a few years of painting. But in case, it may return within a few months or years.

So, it is better to use mold-resistant paint/primer from an excellent company like Zinsser Rust-oleum, Kilz. Otherwise, you may need to bleach if mold attacks again.

Still not sure about it?

Sometimes you may not see the tiny mold. But mold exists in small sizes. Does mildew-resistant paintwork? All these molds spread quickly in the house afterward. For which it is better to choose mold-resistant paint while painting.

Another essential aspect of mold-resistant paint being practical is whether you apply the color correctly. When you use paint on the exiting mold, if you do not remove the mold well, there remains a re-attack risk.

Where Can Mold Resistant Paint be Used?

Mold-resistant paints are usually manufactured for rooms that have a greater entry of moisture or the rooms with a higher amount of moisture in the air. The rooms with more exposure to moisture, include bathrooms, kitchens, humid closets, attic, basement, utility rooms, laundry rooms, shed, greenhouse, garage, etc.

Although applying the paint will not get rid of the moisture issue, but it will reduce or even cease the spreading of mold throughout the walls.

How does Mold Grow?

The primary requirement for the growth of mold is moisture. The three things that mold needs for growth and reproduction in your happy abode are-

  • Mold requires oxygen and it’s everywhere, so we can’t really stop its supply.
  • It needs organic matter on which it would develop. For instance, it can be a fabric, wood, food stuff, or even paint materials.
  • Finally, as I told earlier, it needs moisture. Without moisture, mold cannot grow. Molds reproduce through tiny spores. These spores float through air and land on areas with moisture, that’s when mold and mildew starts developing on such surfaces. We cannot cut out the access to both oxygen or organic material but we can definitely do something about the moisture.

Can Mold Cause Harm to Humans?

If we are talking about health issues here, most molds do not create major health problems or issues for the human body.

Mold spores are a regular thing and they are present almost everywhere. No doubt, they do not possess much harm to us. However, if mold spores roam around or are found in greater quantities that can create probable health issues.

For instance, greater mold quantities can develop allergic reactions in people, and with continuous exposure to more mold spores, one may be at risk of respiratory problems, or coughing, sore throat, itchy eyes, and continuous sneezing.

On the other hand, there are harmful molds that release mycotoxins. If these harmful molds are present in your home, the mycotoxin can create neurological problems and sometimes even prove fatal, especially when you are exposed to them for longer.

And the worst part is, mycotoxins cannot be identified through visual perception. Hence, why take the risk?

Besides, even the mold doesn’t possess any bodily harm; it surely does harm your home which in turn will create manifold problems.

How to Use Anti Mold Paint to Prevent their Growth?

Mold-resistant paints are very similar to apply just like your typical wall paints. However, if you still have any confusion, let me clear out the steps for you-

  1. Begin on a fresh wall with no molds or mildew accumulated on it.
  2. Take a cloth soaked in water and wipe the wall with it. It will get rid of any dust, dirt, or debris of the wall. Let the water dry off completely.
  3. Take your mold resistant primer and apply it to the whole wall along with the nooks and corners, at junctions of the ceiling and floors. Molds have a tendency to grow on such corners, so be careful about it. Give it a whole day to dry up.
  4. Now time to apply your mold resistant paint. Apply evenly and give it about 24 hours to dry completely.
  5. Then you can move on the next coat as you make sure the first coat has dried perfectly.
  6. Remember not to use the room until the final coat has dried completely. And that’s it; easy as a piece of cake!

What to look While Buying Mold Resistant Paint

Having a preconceived notion about everything before buying is actually a boss move.


If you know nothing about the product’s features, you can’t decide which one will be best for you.

Just like when you buy paint to paint your new house walls, you have to make sure that the color will protect your walls from mold at all. In this case, you have to keep in mind some issues that are the subject of this discussion.

Protect from Mold and Mildew with beautiful Paint

Antimicrobial Agents on Paint

Any mildew resistant paint contains a type of material that destroys the microbes in the area where you apply the paint. It also prevents foul odors caused by mold. This material can destroy all visible molds. Although the ability to kill these microbes is lost daily, applying them once every few days can protect them from mildew.

Base of Paint

Different color bases are other. For example, some colors are water-based, some are oil-based, some colors are latex-based. Now which one to choose to keep your house mold-free? If you want to know the experts’ opinion, then, first of all, you need to know that the oil-based color is right for the exterior project.

But never choose water-based colors for the house. Water-based paints can hold water. And the best place for mold to grow is high moisture areas. So, the water base color is not right for the home. You will see that water-based paints dry very quickly but retain water for a long time, mostly if the walls are plywood made.

Latex-based paint is perfect for the house, and it can prevent mold and keep the walls dry. But nowadays, people use water-based colors more for outdoor projects.

Paint Works as Primer

The primer is the first applicable material. However, some colors act as primers themselves. Some companies say that their color primer will work together as primer and lacquer. But that may not always be true. So before buying the paint, find out if the primer will work properly. If the finishing gets perfect when using primer, the color durability is also much higher. But if you don’t use the right primer, your coloring intent may fail.

Coverage of Paint

Decide in advance how many colors you need for space. Every mold-resistant paint does not work everywhere like all other pigments. You can use mold resident paint as primers.

Each gallon of color can give coverage up to 150-400 square feet and more. That’s why measuring the mold-affected area of your house is vital. Then quickly calculate the amount of color you need.

Paint’s Drying Time

Not all best mold resistant paint’s drying time is the same. Some colors dry out in a few hours, while others take days or even weeks to dry. So before applying the paint again, make sure that the previous coating has dried. However, if you look at it manually, all the colors will seem as is dry. But you should not apply the paint before it dries well from the inside.

But to be honest, water-based paint and latex-based paint dry out quickly. Here, oil-based paint takes a lot of time to dry. Again, the drying time depends a lot on the surfaces.

How Long Does Mold Resistant Paint Last?

Between 4 to 6 years!

Pretty straightforward? Well, to be honest, It is challenging to say how long the mold-resistant paint will be useful. Nowadays, different mold-resistant paints are available in the market. The working capacity of paint varies from one to another.

Not all colors are permanent.

The durability of the color also depends on the type of surface you are applying the paint. Because not all places are the same, some have a brick cover, some have wood, and some have plywood.

It is also necessary to know whether the surface you are using is already mold-infested or painting a mold-free wall. If your walls are already mold-affected, the paint may be less effective.

But if you use fresh wall paint that will protect the wall from the new mold, then maybe that color will be more effective. Usually, mold-resistant paint lasts for 4 to 6 years.

What are the Benefits of Using Mould Paint in the Bathroom?

Bathroom is one of those places with exposure to higher content of moisture. Come on! It’s water everywhere and all the time! But you don’t have to worry about the molds and building mildew if you can get hold of some good mold resistant paint. However, why should you? Because of the following benefits-

  1. Anti-fungal benefits:

Molds grow and reproduce by means of spores. But once you apply a nice coat of mold resistant paint on the mold spore-prone areas, you don’t have to worry because the paint prevents the mold spores from forming.

These paints do not have higher exposure to moisture since they are easy to clean up and lock the wall pores to block water seeping inside. Besides, they even possess fungicides to kill mold spores before they grow and spread. Hence, no fungus, no mold, no mildew, no risk of damaging the structure or own health!

  1. Functional benefits:

Look at the shower ceiling, moisture droplets accumulate there the most. A mould paint can keep the mildew and molds at bay which if not applied, the ceiling will be damaged. And the ceiling will not survive there for long.

Hence, there will be functional disadvantages as well, such as you cannot fix your shower there or hang wooden boards on the walls. But applying two simple coats of these paints will take care of the job, so why not?

Final Words……..

Everyone wants to keep his house mold-free. And the first line of defence is to use mold-resistant paint to do the job.

There are many other ways to prevent mildew from spreading. However, it is best to destroy the mold before or during growth. But in this case, it is essential to choose the best paint. Since not all colors are effective on mold, you rely on the mold or mildew resistant paint in this review.

A small patch of mold poses a serious health risk to us. It can also spoil the beauty of the walls or flooring by spreading all over the surface. When you see mold attack on the floor, walls, ceiling of the house, the invasion is already high. So, it is essential to take timely actions.

The mold spreads a foul odor that can cause itchy skin. Mold also carries the risk of death. So, if you are the victim of this problem, take immediate action and save your family.
