    This is Incredible Stuff!!!!
    [This review was collected as part of a promotion.] This is incredible stuff!!!! We never paint anything in or out of our home without using KILZ Primer first!!! KILZ Primer does everything it says it will do. Currently we are painting our kitchen and family room plus the cabinets. KILZ has covered all the stencils, all the old wallpaper marks, and has covered a darker molding. We are beyond thrilled!!! KILZ never disappoints!!!! We will never paint without using KILZ first!!! Thank You for an incredible, amazing product!!!!

      This stuffs a blessing!
      [This review was collected as part of a promotion.] I bought two gallons and painted 3 huge rooms. The walls were dark brown and I painted egg shell white. This primer was perfect. And the musky smells are gone too.

        great coverage on paneling
        [This review was collected as part of a promotion.] I had a oak panel wall and shelving in my dining room that needed a much deserved update. After a quick sanding of the glossy paneling I gave it a primer coat to seal it for painting. Worked like a charm, as always. My dining room looks much better without all that oak wood.

          Excellent for small touch ups
          [This review was collected as part of a promotion.] Since I have the habit of drastically changing my interior wall colors I've used KILZ reliably many times - when a small area of my dining room ceiling needed to be repainted I knew I could rely on this spray to quickly & completely cover the area, leaving it perfectly prepared for my next project.

            My dream come true!
            I have wanted a coffee bar for the longest time, but unable to buy one. So I had constantly looked for a used affordable dresse and at last…..it found me! Coming home one day, I glanced across the street toward my neighbors house and there it was. I waited for them to come outside and walked over to see if they were going to get rid of it. He said he was and asked if I wanted it. Less than 10 minutes later, I had it up on blocks and was preparing to start sanding. Now, this 6 drawer chest was red, ugly red, with glitter on the top and permanent marker writings and pictures. The red was apparently applied to bare unprimed wood and it was not willing to come offf. After 5 days of on and off attempts, it struck me….get KILZ! Within 48 hours, my coffee bar/ storage chest is in use!!

                I thought it was supposed to have coverage…
                We bought a can less than 2 weeks ago, used it soon thereafter and found it was very thin. I could have sworn the product was supposed to be thick enough to cover but it did not. The smell was so intense and lingering that I don’t think I’d be up for a second coat. I’m praying that when I paint over with my white it’ll at least cover the smoke stained part of the wall.

                Response from Giovanna, Kilz Customer CareJul 28, 2021
                Hello, thank you for your review. I'm sorry to hear that the product seemed thin and did not cover well. Typically, even though you can see stains coming through the primer, your topcoat should cover them as the primer is sealing them in. It is a good idea to test your topcoat first on a small area. If the stain bleeds through the topcoat, another coat of a stain-blocking primer will be needed. I'll reach out to you directly in a private email to ensure you have a successful project. Have a great day! -Giovanna
                  Horribly disappointed
                  Just opened a new can and inside was large lump of something inside and parts of dried paint. This was after being out in the machine to be mixed. Complete waste of time and money…

                  Response from Sara, Kilz Customer CareJul 22, 2021
                  Hi Unhappy2021 - Thank you for your review. I'm sorry to hear about the large lump and dried primer in the can you purchased! Our primer should have a very smooth and creamy consistency, and I'm concerned that this wasn't the case for you. I've reached out to you via email to assist you with this further. Thank you again for reviewing our primer, and I hope to hear back from you. - Sara
