Medias for Powder Coating Media Blasting

There are many type of medias to choose from when blasting. Having the ability to blast opens up a lot of options in the garage, not just for powder coating. For now, I will talk about the type of media that you want to use for powder coating prep.


Coal slag: This media is very cheap, it leaves a good profile, and it lasts a pretty long time. It is great at stripping paint and rust very fast. Examples of coal slag is the popular brand: Black Diamond, its sold at Tractor Supply Company. 50lbs is about $7.


Aluminum Oxide: This is a very aggressive media that easily removes rust, paint, and is more efficient at removing powder coat than the coal slag. It is pricier, but it lasts longer. This leaves a great profile in a steel or iron part to be powder coated. If you are doing any ceramic coating, you must use aluminum oxide to prep. Although when blasting aluminum, you need to be careful not to leave too much of a profile, as aluminum is much softer than steel. Hold the gun back further and lower the air pressure.


Sand: Sand is the cheapest. You can get a bag of play sand from Home Depot for next to nothing. However, sand is very dusty, making it almost impossible to see in the cabinet. Sand also produces silica dust when blasting which can severely damage your lungs even when using a cabinet. The only safe way to use sand is with a supplied air breathing system.
