A:  Hi Blac, thank you for your question. As it turns out, we don't advise using any of our primers on bathtubs because they are not designed to be submerged in water or have constant contact with it. This can cause the product to fail, and we want to ensure that your project is a successful one. Instead, we recommend you visit your local hardware store and ask for a product recommendation best suited for your specific project needs. Good luck with your project! - Alex

A:  Hi Timmy, thank you for your question. The Kilz Mold and Mildew Primer can be applied to plaster walls, providing excellent stain-blocking benefits. However, it's hard to say exactly what could be causing this to occur on the ceiling. If the liquid has left a stain on the ceiling, we recommend thoroughly cleaning and allowing the surface to dry before spot priming using the Kilz 3 Premium Heavy-Duty Stain-Blocking Primer or Kilz Original Primer and top coating with your preferred paint. Have a great day! - Randy

A:  Hello, thank you for your question. Yes, Kilz Mold and Mildew primer can be used on previously painted surfaces. The surface should be sound, clean, and scuff sanded to promote adhesion if the previous finish is glossy. Have a great day! -Giovanna
