What Does Kilz Do For Mold

Can I Paint Over Mold With Kilz

How To Apply Zinsser Mold Killing Primer

Kilz, or KILZ, is a company that offers primers and paints. When it comes to mold, their most relevant product would be their Mold & Mildew Primer.

It works as an all-in-one primer, sealer, and stain blocker for high-humidity areas where mold is known to develop. Some of their own listed examples are bathrooms, laundry rooms, and busy kitchens.

It works by coating a wall and then having paint spread over it. The use of primers like these is great for anchoring the paint to the wall.

EPA-registered ingredients in the mixture then create mold-resistant barriers to prevent mold or mildew growth. As a stain blocker, it also stops stains in its tracks.

While that all sounds great, theres no such thing as primer or paint that can roll over mold and destroy it. Mold has its reputation for being persistent for a reason, after all.

KILZ, and similar products, would be a great thing to have before the mold even started. If you had them, you may have prevented the current mold problem.

That said, you cant paint over the mold. If you want to explore those products, apply them after the mold has been dealt with to ensure it never rears its head again.

What Makes It So Dangerous

What makes mold so dangerous is the mold spores it releases in order to reproduce. The spores become airborne, especially when disturbed by rubbing or cleaning, and they can be breathed into the lungs. When these spores are inhaled, serious lung infections may occur. 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.

Mold sealant is far from a guarantee against mold if you are able to deal with the mold completely you absolutely should since an overly stubborn mold can keep spreading even after the mold sealant and paint has been applied. This isn’t to say that mold sealants don’t work, they do.

Does Kilz Paint Kill Mold

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.

Reason : The Moisture Source Needs To Be Addressed

Even if you address the mold properly, the moisture source that is feeding the mold needs to be taken care of in order to prevent the mold from returning. So if you want to actually get rid of the mold for good, you will need a professional to identify and fix the issue that is causing the moisture in your property. In addition, you will need to dry or get rid of any water damaged building materials because they are prime breeding grounds for mold. The good news is that our nationwide network of mold remediation contractors, can do all of this for you.

This is a problem best suited to the professionals, but if you must do it yourself the number one priority is the safety of you and those around you. This can be a very hazardous task, if you do not take every precaution to contain and remove the spores properly.

The first thing youll have to think about is containment, you dont want to spread the mold spores while you clean the area. Youll want to seal off the area with plastic sheeting, making sure all seams are properly sealed.

Once the area is sealed off, youll need the appropriate clothing.

Easy Steps To Paint Over Mold

  • Dont breathe the spores: put on your respirator . Scrape off any loose mold and recover it for disposal.
  • Dont be tempted to use bleach: its deadly and will make the problem WORSE. Thanks to a generous reader who pointed out that bleach can make the mold that survives stronger and faster to multiply.
  • Put rubber gloves on for any toxins: dont go dollar store on this one: re-use quality gloves many times over. This prevents chemicals from touching the skin. There is no reason to take a risk with your health ever.
  • Wipe with any rag until no more black/green comes off.
  • Rinse the surface with clean, wet rags. Leave rags outside away from people/animals.
  • Let dry your first coat should be a mold killing or resistant primer, then two coats of mold resistant paint.
  • If you have a very large area to treat, you can use a sprayer with your mold killing paint You would not want to use your garden sprayer here as the plastic will probably not handle the bleach solution well. Conversely, a sprayer that works with bleach will probably also be fine with garden solutions. Bleaching inside can be very deadly: choose from the respirators above.

    We like this eco-safe mold-killer which comes in large one- and 5-gallons as well as spray bottles. Spray and let dry. It leaves a mold-blocking film that can be painted. We use a garden sprayer to apply solutions like these as well.

    When you hear about anti-mold paint, it is not a mold-prevention paint and certainly not a mold killing primer.

    • Home safety
    • Property damage
    • Long-term costs

    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!
