Sandblasting is one of the most efficient means of removing rust, corrosion, and old paint from metals, plastics, stone, and wood. Depending on the application, abrasive blasting can create a bright, shiny surface, rough up smooth materials, and even reshape some substances. If you want to refurbish a rusted metal item, below is some information you should know about the sandblasting process.

A Guide to the Sandblasting Process

Choosing the Medium

While silica sand was the preferred medium for sandblasting, it is no longer used due to health risks posed to workers. These days, blasters use baking soda, glass beads, steel grit, and a variety of other abrasive materials.

Glass beads are typically best if you’re creating a matte or mirror finish. Steel grit and baking soda are generally used to remove paint from metallic surfaces without marring the underlying finish.

Preparing the Cabinet

To keep abrasive materials from spreading all over the shop, abrasive blasting is usually done inside of a cabinet. These cabinets are sealed, with rubber gloves attached that allow technicians to manipulate the object inside.

The technician will need to adjust the air compressor, which provides the pressure the machine uses to smooth out the surface. Finally, any sensitive equipment in the shop should be covered to protect it against any grit that escapes the cabinet.

Sandblasting the Item

Using abrasive blasting is a difficult process that requires training and patience. The technician will then use the nozzle inside the cabinet to make short, lateral movements across the object being blasted. Starting on one end, continue the process until the object has been cleaned of rust or the surface adequately prepared.
