Abrasive blasting is a useful and often times a necessary
pre-treatment to obtain a clean surface, or an aggressive profile prior to
coating. In order for the powder to adhere to the metal surface, the surface
needs to be completely clean and free from any previous paint, rust, dirt, or
minor imperfections especially around weldments. In order to ensure a proper
surface for powder coating, abrasive blasting is often the only way to
accomplish this high standard of cleanliness. This step in the process should
not be compromised, it is vital for the durability and longevity of the powder
coated finish depending on its intended use.
For your convenience we have two on-site blasting units.
Our largest unit is 8’ x 8’ x 20’, and our small unit is 3’ x 3’ x 3’. We use
Aluminum Oxide, which is an angular media which gives the proper profile for the
metal surface to be prepared and cleaned without harming the metal itself. We
have found that the angular quality leaves a superior surface for the powder
coating to adhere to, versus bead blasting, which leaves a round profile on the
surface. Both will work, it just depends on the intended use of the item to be
painted; decorative vs. functional.
