Metal surfaces are susceptible to rust and corrosion. To protect such surfaces, you can use protective paint coatings or other corrosion protection systems. However, before you can apply such protection, the experts at Euro-Blast NZ Ltd recommend that you first need to prepare the metal surfaces for the application of the coatings.
Preparing the metal for the protective coating
You need to prepare the metal surfaces of structural materials, vehicle bodies, and other metal items so you can make sure that the coatings would adhere to the metal surfaces. Any contaminants and residue on the surface would result in poor coating performance.
You can use hand and power tools to manually clean surfaces. You can use scrapers or wire brushes, although these tools are relatively ineffective in cleaning surfaces. Alternately, you can use power tools like percussive reciprocating needles, right-angle grinders, and rotary abrasive coated flaps. Just make sure that you know how to use these tools efficiently.
Power tools offer a good way to clean surfaces, but you can also use acid pickling. Acid pickling involves immersing the metal surface in a solution of inhibited acids. The method can be 100% effective, and can clean off all rust and contaminants. Experts use this technique for cleaning structural steel.
Perhaps the best way to prepare metal surfaces for coating application is abrasive blasting. Abrasive blasting shoots material such as sand or garnet at high speeds to clean surfaces such as metal. You can use abrasive blasting for your surface preparation, but make sure you have the proper safety equipment and tools.

Preparing a metal surface is something you can do on your own, but the process poses several health hazards and risks. It would be best to consult professionals who can do these and even apply the protective coating on your metal items.
