In addition – Surface preparation: For best results, ensure surface is clean, dry & free from loose paint, mould & mildew, wax or oil. If wax has been used, clean the surface thoroughly with white spirit. We recommend that bare wood should be sanded before painting. Hard glossy surfaces should be abraded before painting. Cover surrounding areas to protect from spray mist.

Also – You can apply this to a multitude of other surfaces such as Metal, Wood, Plastic, Ceramic and even Glass with the correct preparation.
