Specially formulated to prevent mildew (and potentially mold) from growing on the primed surface before paint is applied, KILZ Mold and Mildew Primer contains active ingredients that are registered with the Environmental Protection Agency. This mold and mildew resistant film protects the primer film, sanitizes the surface it is applied to against fungi organisms and helps ensure a fungi-free primed surface for painting. KILZ Mold and Mildew Primer blocks stains such as markers, lipstick, food stains, smoke, nicotine, grease and more. This primer has a thicker consistency compared to most non high build primers which helps achieve a more uniform finish. The primer also helps paint bond to multiple surfaces and ensure years of topcoat integrity. Use over and under alkyd, oil and water based paints, this primer dries quickly, has a low odor and is environmentally conscious with little to no volatile organic compounds.

Kill Mold and Mildew interior/exterior primer work
[This review was collected as part of a promotion.] I have used this product on mold in our basement wall and also on sub-flooring in several spots inside our renovation project. It covers great, dries quickly, and there is little odor.

    [This review was collected as part of a promotion.] I have a client with over 300 units in South Florida, with all the humidity and rain mold can build up quickly. We started implementing as part of our schedule maintenance to paint all AC closets with Kilz Mold & Mildew Primer and the results have been great!

      Did not like this
      With this many positive reviews it seemed great before I started to paint. Its not sticky at all over joint compound. I cleaned the walls very thoroughly before. See picture. The coverage is ok but It’s the worst primer I’ve painted with.

      Response from KILZProblemSolverAug 19, 2021
      Hi Andre - Thank you for your review. I'm sorry to hear that this primer isn't sticking to the joint compound on your walls. Based on your picture, it looks like the primer may be pulling off the surface in these areas. To fix the finish, I recommend adding up to 4 oz. of water per gallon to your primer, mixing it in thoroughly, then re-priming. For further assistance with your project, please feel free to reach out to us directly. We'd be happy to help. - Sara Kilz

          Difficult to apply
          I bought this product to repaint our bathrooms. From starters, the product was too dense. Since there were no instructions about adding water to thin it, I used a standard paint roller. The results were horrible, as the primer would no adhere well to the paint or cover pores on the surface. Moreover, it would not spread uniformly and require extreme pressure on the roller. With sore arms, I added some water to the primer in the pan, which thinned the primer a bit but did not improve coverage. See the photos below. I want to know how I fix this mess, as I am not going to paint on the primer until I get it right.

              Great barrier for van reno!
              [This review was collected as part of a promotion.] We applied 2 coats of kilz to our base floor in our van renovation prior to laying linoleum. I feel confident that kilz has created a safe barrier for the floor!

                  Amazing!
                  [This review was collected as part of a promotion.] I had a mild issue in my bathroom and I decided to try KILZ and it was the best thing I could have ever done. I cleaned and scraped the area: The mold dissapeared and was never to be seen again. It was amazing and I'm glad I went with my gut feeling to use this product because it was worth it.
