What Customers Are Saying

Customers overwhelmingly praise this mold-killing primer for its exceptional effectiveness, with most reporting visible mold elimination after a single coat that doesn't return—even in bathrooms and basements. Reviewers highlight smooth application, quick drying, and excellent coverage that often eliminates the need for multiple topcoats. Many note improved mold allergies and appreciate that it works directly over existing mold without complete removal first. While the odor is noticeable, most find it tolerable compared to harsh alternatives. A few mention adhesion issues on certain surfaces or wish for smaller sizes, but overall customers consider it a reliable, time-saving solution.

Very easy to work with

Would Recommend

I am not an experienced painter (just a home improvement DIY-er) and I found this primer very easy to work with.

Mold Killing Paint

Would Recommend

Works great. Was recommended by Lowe’s employee. Clean up the area and paint over it and forget about it. Keeps the area mold free! Haven’t seen a problem comeback yet.

Zinsser Mold-Killing Primer

Would Recommend

This primer works very well. We had about a dozen 10' lengths of pre-primed MDF baseboard trim stored in our garage, and with all the rain this past spring the room was damp and that caused the moulding to get moldy. There were spots of mold and mildew all over these pieces of trim. We sprayed each piece with Concrobium Liquid Mold Remover. Once that was dry, we wiped each piece with a rag and then painted them with the mold-killing primer. The trim is still in the garage awaiting a top coat of ...

Works great but be careful

Would Recommend

As professional painters, we use this all the time to cover mold with outstanding success. I really recommend this product as a problem solver and time saver. CAUTION: DO NOT spray unless full PPE. Respirator and skin covered. I was in a room where this was sprayed, 30 feet away from the application area. I was not wearing PPE while talking to the contractor. Within 4 hours of breathing it, I was deathly sick. It took a few days to finally recover. Read the can. Do not use without vent...

Great product.

Really works well to kill mold and mildew. Is a good covering primer as well. We've used it out bath and bed rooms and on our shed outside.

I was painting a wall that had mold growing. I didn’t want it to come back so I used it and it done a great job. Then I was able to paint over it.

does the job

Would Recommend

We had some mold on a piece of wood under a pool. We covered the wood with this primer and so far so good - it looks better (we didn't even paint over it with regular paint) and we have not had any new developments with mold. Mary

True one coat coverage!

Would Recommend

I used this and when I ran out went and got a cheaper brand that claimed to do the same. It took 4 coats and still didnt fully cover. Will stick with this from now on!
