Questions & Answers

Can this product be used over rust
ByOct 31, 2026

Answer This Question

Hi abcd, thanks for your question. We recommend removing all loose rust from the surface before application. If there are leftover rust stains that will not come off, it's okay to prime over these areas with our Multi-Surface Primer. Good luck with your project! -Christina

      Answer This Question

      Hi Jerri, thank you for your question. Our Multi-Surface Primer and Sealer No. 436 can be tinted with up to 4 oz of tint per gallon. Tinting the primer will help achieve the color of your topcoat in fewer coats, and a great idea when using rich and dark colors. Good luck with your project! -Giovanna

          Hi Ceril, thanks for reaching out. Our Multi-surface Primer does not provide UV Protection, as this product is designed to be topcoated. Enjoy the rest of your day. -Christina

            I am thinking of using on a wall of stucco with only 10 days of curing, is this product ideal for this job? The pH can be between 10 and 15!!

            Hi Samuel99, thanks for reaching out. We don't recommend using our Multi-Surface Primer on a new stucco surface that has only cured for 10 days. We recommend letting the surface cure for at least 30 days before applying this primer. Enjoy the rest of your day. -Christina

                  Exceptional coverage for preparing multiple types of surfaces. We used this primer on masonry, unfinished drywall, and wood and it provided a great bonding surface for paint. We followed the instructions and highly recommend this multi-surface primer.

                  This primer worked great on my wooden front door after I removed all the old paint and provided a great base for the alkyd paint.

                  Does not adhere to plastic as specified
                  Applied this to our vinyl plastic hot tub panels beneath a coat of BEHR black acrylic enamel. One day later it’s peeling off in big sheets. We washed and sanded the surface for better adhesion. Applied as directed. Now we don’t know what to do. It’s ruined our hot tub. Not sure how to fix this.

                    This paint is simply awsome to work with! The finish looks like I sprayed it when I used a roller and brush

                    Primer / Sealer Ceiling Paint
                    Used this on an unpainted 20 year old stucco ceiling and the product covered the area well with very good adhesion. I applied 2 coats of this product before finishing the project with 2 coats of ceiling paint. It seems like a lot of paint, but the finish looks great. I should also add that I started this project not knowing that the ceiling had never seen a lick of paint. Subsequently the regular ceiling paint applied just soaked into the stucco like a sponge. If you need to apply a sealer coat I would recommend this product without hesitation.

                    I used this on melamine which is plastic coated practical board. It worked well to form a foundation.

                    When I bought my house, built in 1915, a previous owner had put water-based paint over oil-based paint, and it was peeling everywhere. My contractor had to use a grinder with sanding wheels to get it back to bare wood. He wanted to use Sherwin Williams oil-based primer, but I had done my research and insisted on this Behr primer. After finishing a huge dormer on the back of the house, the first part to be painted with two coats of primer and two coats of paint, my contractor warned me that in a couple of weeks there would be a few blisters in the paint but that this always happens and he would sand them down and repaint them. There has never been a single blister. My contractor has to wear latex gloves when he uses this primer, because when it gets on your skin you can't wash it off. My huge old house looks amazing now. People driving by stop to tell me how pretty it is. And my contractor is now recommending this Behr primer to people!

                    Excellent primer. Just one coat did the job.
