Mold can be a tricky problem to deal with, since it can potentially cause health problems if not dealt with properly. If you’re considering using Kilz to cover up mold, it’s important to understand a few things about the product first.

Kilz is a brand of primer that is designed to cover up and seal various types of surfaces. It is often used as a first layer of paint on walls, since it can help to prevent bleed-through from happening. Kilz is also sometimes used on wood or metal surfaces that have been affected by mold, since it can help to create a barrier between the surface and any paint that is applied over top.

It’s important to note that Kilz is not necessarily designed to kill mold spores that are already present on a surface. Rather, it is meant to seal them in so that they cannot spread or grow any further. For this reason, it’s important to make sure that any surface that you’re planning on painting with Kilz is thoroughly cleaned beforehand. Any mold spores that are left behind could potentially continue to grow, which would defeat the purpose of using Kilz in the first place.

If you’re dealing with a small amount of mold growth, it’s generally safe to assume that Kilz will be effective at preventing any further spread. However, if there is a large amount of visible mold growth present, it’s best to consult with a professional before proceeding. They will be able to advise you on the best course of action for your particular situation.
