Sandblasting & Surface Preparation

Sandblasting is a general term often used to describe abrasive blasting. Media blasting is a broader term that includes different types of blasting materials such as sand, coal slag, glass bead, or other abrasives. The media selected depends on the material being cleaned and the desired surface profile.

Yes — when performed correctly, sandblasting removes rust, corrosion, mill scale, and old coatings down to clean metal. However, if deep pitting exists, blasting removes the corrosion but cannot restore lost material thickness.

Improper sandblasting can warp thin materials or damage delicate components. That’s why media selection, pressure control, and operator experience matter. Thinner metals and aluminum require different handling than structural steel.

In most cases, yes. For proper powder coating adhesion and durability, rust, old coatings, and surface contaminants must be removed. Media blasting creates the correct profile for the powder to bond properly.

Time depends on the size of the part, level of corrosion, and amount of old coating present. Smaller parts may be completed quickly, while heavily corroded structural components require more time.

After blasting, parts must remain clean and dry. Depending on the material, they may move immediately into coating or go through additional pretreatment steps to prevent flash rust.
