Acrilex 100ml primer for metals, PET, and glass creates an adhesion base and provides anti-corrosive protection on non-porous surfaces. Ready to use and water-soluble, it is easily applied with a soft brush or sponge to glass, PET bottles, aluminum, iron, and previously cleaned galvanized sheets. It dries in 4 to 6 hours, forming a matte film that protects the metal against corrosion and prepares the surface to receive acrylic, PVA, or Metal Colors paints. On pieces with previous varnish, light sanding before application is recommended. This primer is indispensable for recycling projects, decorating cans, and crafting with glass bottles.
