Review: Zinsser Mold Killing Primer — The only primer that actually kills mold, not just “prevents” it - I didn’t even know this product existed until a customer told me about it back when I worked at Wally World. They were dealing with a major mold problem in their home, and every time they used Kilz, the mold came right back. After doing their research, they found this primer — the only one marketed as a true mold‑killing primer instead of just a mold‑resistant one. That stuck with me. Since then, I’ve used it myself several times, and it’s been consistently effective. Real‑world results: - Warehouse drywall: We had constant mold issues from dampness. We painted the affected areas with this primer — no topcoat, just two coats of the primer — and it stayed clean the entire time I worked there. (And honestly, the coworker who applied it didn’t even clean the walls first, which is not recommended, but it still worked.) - Flood‑prone basement: Even after cutting the drywall higher to avoid water contact, the leftover dampness kept causing mold. I used this primer on the walls, and the mold didn’t return while I lived there. - New house with vent moisture issues: One storage room had a massive mold patch on the wall. I cleaned it as well as I could — not perfectly — then painted it with this primer. Months later, the mold still hasn’t come back. Bottom line: If you’re dealing with mold and you’re not confident you can remove every last trace before painting, this primer is absolutely worth it. It saves time, reduces stress, and actually kills what’s there instead of just hoping it won’t return.
Review: Does its job but smells! - Strong smell but it did the job. It dries quickly and has helped stop a mold issue. The white color looks nice but you can also paint over it. It’s a good quality and a little goes a long way. The paint is thicker so it had great coverage and does what it’s supposed to!

## Questions & Answers

**Q: will this remove water stains?**
A: It worked very well on the small mold discoloration. I'd try it for water stains because of the completed coverage on the darker mold stains. Seems as opaque as would be needed....

**Q: Need to wait 2 days before applying second coat to undersink area. Is that a problem?**
A: I do not know for sure; I used the stuff in an un-ventilated cupboard and applied 2 coats as 1/day. I do not recall anything thing that conditioned application other than to be sure that the previous coat was dry. Clearly there is some chemical reaction going on, but once dry one may imagine that the process is complete? Good luck.

**Q: Did this get rid of mold? For how long? Did the mold come back later?**
A: Yes it did get rid of the mold. There are a couple of spots where the mold is returning but they seem to be areas that did not get as much paint but even those areas took about 6 months to return. I highly recommend  this item in fact I am planning to order more for another room. T

**Q: Why does this say recommended for metal,non porous surfaces but shows wood walls as the objects used on,painted with?**
A: I used in on a concrete floor

### ⭐⭐⭐⭐⭐ Does its job but smells!

Strong smell but it did the job. It dries quickly and has helped stop a mold issue. The white color looks nice but you can also paint over it. It’s a good quality and a little goes a long way. The paint is thicker so it had great coverage and does what it’s supposed to!

### ⭐⭐⭐⭐⭐ Kinda thin but works great on mold.
*by S***L on November 12, 2025*

A little thin but I’m guessing it’s because of the mold killer. Covered great and no more mold smell. If I run into more mold I’ll definitely buy this again.
