Why is prepping the material so important?

What happens if the metal is not prepped properly?

  If the coating on the material is defective or there is a contaminant present and the metal has not been properly prepared before powder coating, there are several defects that can occur in the finished powder coat’s appearance as well as its ability to allow the powder to attract to the metal during the spraying process. 
​ If dirt is present, either within the powder coating mechanical system or even in the air within the spraying booth, the finished product can have evenly distributed or random patches of “lumpiness” in its appearance.  Extreme care must be taken to ensure a clean booth and operating system in addition to meticulously cleaning the material of any grease, dirt, or residue prior to coating the metal.  We clean all our iron initially with acetone.  It is a slightly acidic, organic solvent that most people associate with paint thinner or nail polish remover.  It is also a substance that is produced in and removed from our own bodies in metabolism.  Once the metal is thoroughly cleaned of all contaminants, it is hung on large racks and placed into the booth, ready for the powder coating process.
