Sandblasting and shot blasting are both abrasive surface preparation methods, differing mainly in how abrasives are propelled. Compressed-air sandblasting offers flexible access to large, complex or on-site structures, while centrifugal wheel blasting delivers efficient, consistent treatment for batches of regular parts. Garnet abrasive, with its non-metallic, low-dust properties, is an ideal choice for compressed-air sandblasting to achieve reliable cleaning and coating adhesion. Read More
