How should I prepare metal before painting?
Any loose and flaking paint should be removed and all surfaces should be cleaned, and degreased with Coo-Var Universal Degreaser. Any rust should be removed, and surfaces should be abraded to make sure an adequate ‘key’ is produced. If the surface is galvanised, mordant solution should be used to etch the surface prior to painting.
Remove any existing rust using a mechanical sander or a wire brush.
