Questions & Answers

Can I apply KILZ oil base primer over water base paint?
ByAug 12, 2026
1 Answer | 
Answer This Question

Hi Rick, thank you for your question. Yes, the oil-based Kilz Primer can be used over water-based paint in good condition. The surface should be sound, clean, dry, and scuff sanded to promote adhesion if the finish is glossy. Good luck with your project! -Giovanna

    Hi Ron, thanks for reaching out. Our Kilz Original Primer can be used over chalkboard paint. While it may not cover completely on it's own, it will help your topcoat cover in fewer coats. Good luck with your project! -Christina

      Can I use Kilz as a heat reflecting cover on my asphalt shingles roof? It's only to reflect some of the UV rays and heat. If yes, which product do you suggest? Average summer temp is 115°-118° and stays that hot at least 5 months out of the year.

      Answer This Question

      Hi there, thanks for the question. I wouldn't recommend using any of our primers om a roof to reflect heat. Also our primers aren't meant to be left uncoated and need to be top-coated with paint within 30 days. If you have additional questions about your project, please reach out to us directly. Our customer care team is happy to help. -Ronald

        Which which one of these would be best to come and help cover up wallpaper
        ByMar 21, 2026
        1 Answer | 
        Answer This Question

        Hi Danny. Thank you for your question. It's recommended to prime the wallpaper with an oil-based primer before coating. This is to prevent the glue from reactivating. Our Kilz Original is a great choice. After priming, you can apply your paint of choice. If you have further questions or concerns, please reach out to us directly. We are always happy to help. -Alex

          I just applied two coats of Zinzer bull’s-eye 123 primer to a previously stained exterior door. I now have something bleeding through the new primer. Can I apply your product over the Zenzer Bull’s-eye. If yes, how soon can I apply it?

                Can use on flex seal liquid?
                ByNov 4, 2025

                Answer This Question

                Hi Gary, thank you for your question. Our Kilz Original Primer can be used on paintable sealers. However, please note that it has not been tested specifically on flex seal liquid. I advise reaching out to the manufacturer to confirm if the products are compatible. You can also apply the primer to a small area to test the performance. Have a great day! -Lina

                  I’ve used a lot of primers over the years and KILZ Original White Oil-Based Primer is still one of the best for difficult jobs. It covers stains extremely well, blocks odors, and sticks to almost anything. I used it on old patched walls and stained trim before painting, and the final finish came out much smoother and more even. The coverage is excellent, it dries fairly quickly for an oil-based product, and it gives a really solid base coat. Definitely worth the extra effort compared to cheap water-based primers when you need real stain blocking and adhesion.

                  Amazing sealing all Ive tried it on
                  [This review was collected as part of a promotion.] I love this stuff, always the first step of any floor or anything that moisture can hurt around homes and business alike. It really provides a water/moisture barrier from about anything you can throw at it. It is a game changer in restrooms and kitchens, floors, walls or ceiling, but I use it mainly on subfloors when I floor homes for customers

                    Don't hesitate to buy!
                    [This review was collected as part of a promotion.] I purchased a gallon of Kilz Primer for interior and exterior and I'm nearly out. This stuff is fantastic. I've used it on dressers, cabinets, chairs, railings, patio furniture, porch railings, deck furniture, and much more. It covers everything and makes painting easy. Get yourself a gallon and get your stuff painted!!

                        Great Coverage
                        [This review was collected as part of a promotion.] By using this high-quality primer, I was able to achieve significantly better coverage and a smoother, more polished finish with the paint application. The colors are vibrant, and the overall look of the house has been enhanced remarkably. It now stands out beautifully in the neighborhood and looks absolutely fantastic.
