Artiteq profiles are lacquered using a polyester-based powder coating which is generally easy to overpaint. The primer version can be overpainted using commonly available lacquers (latex-based, acrylic-based or alkyd-based). If you intend to overpaint the profiles, you must first prepare the surface. It is sufficient to remove any excess grease (preferably using surgical spirit) and slightly polishing it with fine sandpaper.
