Black mold spores are especially dangerous and they can cause lasting health conditions.

Furthermore, mold can cause skin and eye irritations. It can worsen or even cause the symptoms of asthma and allergies. It is therefore important that mold is eradicated from the home before it could take a hold on your health. It is also imperative that a mask is worn when working with mold.

Do Mold Killing Primers Really Work

According to Rust-oleum, the maker of Zinsser, Zinsser Mold Killing Primer does actually kill the mold and prevent future mold growth.

However, I believe some healthy skepticism is in order.

For me, there is no reason in world to not clean the surface with a bleach mixture before painting. This is a known way to kill and clean mold and bleach is super cheap and can be purchased anywhere.

NOTE: Bleach will kill mold that it comes into contact with, however, it will not do a great job on porous surfaces such as drywall which I discuss more here.

In my professional opinion, it most likely works, but why not kill and clean the area with bleach first to make sure? Your health is worth a small extra step!

How Does Mold Grow

Mold needs three things to grow and reproduce in your home.

First it needs oxygen, which there isnt much we can do about.

Second, it needs organic matter to feed off of such as wood, paint, fabric, foods and other materials.

Last, mold needs moisture. Moisture is the key to mold growth in your home. We cannot cut out oxygen or organic materials in our homes, but we can control the moisture found in our homes.

But How Do I Get Rid Of Mold & Mildew

Thatll require a few remedies outside of paint use.

There are multiple ways to approach that problem. Some are effective, others not so much. They are:

  • Bleach
  • Specialized Remover Agents

Bleach can be effective for minor cases. But in most situations, itll simply change the mold color .

Vinegar is slightly effective since it carries anti-bacterial and anti-fungal properties. However, it wont kill every type of mold.

But those arent the only problems with those remedies.

How To Apply Kilz Directly To A Wall

You may wonder how to apply Kilz directly to a wall. In fact, it is possible to cover about 300 square feet of wall area with just a single coat of the product. However, you must be aware that Kilz can absorb moisture and damage the substrate if it is not applied properly. In order to prevent this, it is best to use a high quality synthetic brush or roller with a 3/8 to 3/4-inch nap. You may also want to use an airless sprayer with a tip that is.021 to.021 inch and 60-mesh filter.

Before applying Kilz, you should thoroughly clean the walls. If the walls have mold or mildew, it is best to remove it using a mildew-removal product. If the surface is already clean, then you can apply Kilz without precleaning it. If the surface has mildew, you should rinse the area with water and let it dry completely. However, do not apply Kilz directly to mold-ridden surfaces. The fungicidal property of Kilz will prevent the fungus from returning.

Additionally, Kilz doesnt solve the problem directly, but it can greatly limit its growth. This makes it a good choice for those who want to prevent mold growth from affecting their property. If youre unsure about whether Kilz can be used to treat mold, make sure to contact professionals who specialize in this area for advice.
