Keys to successfully sandblasting a powder coating surface

l 100 grit aluminum oxide media is a good choice for a blast media, it's more efficient than coal slag or sand at removing powder coating and does not create the dust issues that sand does.

l Having the ability to maintain a minimum working air pressure of at least 15 cfm at 90 psi combined with the proper blast media, will make the job of blasting powder coating easier and more efficient.

l Media selection and air pressure are key to making the process a worthwhile exercise.

l Powder coating is meant to be very durable, and thus sandblasting can be an aggravating process if your equipment is not up to the task.

l Delicate parts may not be able to withstand the pressure they are subjected to during the blasting process without warping or other damage occurring. In these instances other powder coating removal techniques may need to be used, such as a chemical stripping agent or the use of a burn off or hot strip oven.
