Is there a special adhesive to tile over painted cement?

Yes, there are specific adhesives designed for tiling over painted cement surfaces. It's important to use a high-quality thin-set mortar or a modified adhesive that adheres well to both the paint and the tile. Before applying the adhesive, ensure the painted surface is clean, and consider roughening the paint with sandpaper to improve adhesion. Additionally, it's advisable to check if the paint is stable and not peeling to ensure a successful tile installation.
