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 painted or powder coated finish depending on its intended use and substrate.
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 steel grit, 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 profile for paint or 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 and delicacy of the item to be painted; decorative vs. functional.
