How to Paint over Mould & Mildew

Once your mold killing primer is dry, youll want to paint over the area with a mold resistant paint.

Does Painting Over Mold Or Mildew With Kilz Paint Kill Them

If you are wondering if painting over mold and mildew with Kilz mold and mildew resistant primer will kill the mold and midlew, the short answer is no. Kilz was designed to prevent mold and mildew not to kill them once they have already grown.

Things Needed Before Painting Over Mold

1. Safety First

Many people try sanding over a mold-infested wall to clean it before painting, but this isnt the right thing to do. When you sand an infested surface, the tiny particles spread all around the air, which is not something youd want. It reaches directly to your lungs, which can be very dangerous and potentially deadly.

If the mold infestation is that bad, wed strongly suggest calling a professional. This might cost you some extra bucks, but the overall safety makes it worth the investment.

But if you find yourself capable of doing it well, wed advise taking necessary precautions, like wearing 3Ms full-face respirator and rubber gloves before sanding. It will protect you from inhaling mold particles.

Putting on rubber gloves is always important to avoid contact with toxins that might be present in the paint. They prevent the chemicals from touching the skin, and you might not want to take any chances with your health. You will find quality gloves that can be reused multiple times.

Some may only be meant for single-use and should be discarded after a certain number of uses. Also, make sure to discard them properly, away from humans and animals.

Just make sure to avoid any bleach-formulated paint on the surface it can even make the mold problem worse. Furthermore, always wear quality rubber gloves while working to remove the mold.

Most Common Places Mold Is Found In The Home

Since moisture is a required ingredient in the growth of mold, high moisture areas in your home are the most susceptible to mold growth.

These areas include bathrooms, kitchens, laundry rooms, humid basements, cabinets under sinks, plumbing areas and storage rooms among other places.

These are the areas that you should always keep an eye on for mold growth. The sooner you catch it, the easier it is to deal with.

One area Ive personally dealt with mold is in the basement of my home when I first moved in. Non-green treated wood was used for the sole plates and drywall came into contact with the concrete floor. This allowed moisture to form on the organic materials in my basement and cause significant mold growth on the framing and drywall. I had to gut and redo my entire basement.

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!
