Can the paint be applied over any substrate?

In almost all cases, the answer is yes. Any paint can be applied over any type of surface as long as this latter has been properly prepared and/or primed with the specific adhesion primer. Without adhesion primer, the paint adhesion cannot be guaranteed! Some substrates, such as metal, plastic, glass, concrete, leather, etc., require a primer. Other irregular substrates, such as wood, require a primer to smooth the surface. Other supports, such as old paints do not require primers; a light sanding is sufficient to allow them to be covered while ensuring a good adherence.
