Can you powder coat over existing powder coating?
Hands down, one of the most frequently asked questions in this business…about powder coating.
Yes! Typically if the coating is newer and recently powder coated. However, there are some variables that could play into whether you should coat over it or not.
Is the current coating sound and without flaws? If the coated metal project has imperfections i.e. bubbling from outgassing, fish-eyeing or spots where the coating has resisted, recoating may not be the first solution.
Was it cured properly the first time? If the original coating hasn’t cured properly the first time recoating will not be the solution this time.
Is there existing rust or corrosion from exposure already? As expected re-coating would not be the solution here because powder coating does not stop the process of decay.
Is it a painted finish instead of being powder coated? Believe it or not, many customers bring in projects they assume to be powder coated when in fact they are painted. We find this especially in the outdoor furniture and fixture market because many of those products come from China and have the appearance of being powder coated when in fact they are not.
Determining these important features to your metal project is best left to the experts. Something as easy as a color change or color match may not be so simple.
