Pre-Paint & Coating Surface Preparation
Surface roughening by blasting so coatings adhere better to the metal.
Overview
Roughening a metal surface before paint, powder coating, metallization, and other coating processes is a fundamental manufacturing step that ensures better adhesion of the coating to the surface. From automotive parts such as chassis, wheels, and engine blocks to pipelines and ship plating, pre-paint blasting is an industry-standard practice across a wide range of applications. The consumable used and the grain size vary according to the target surface roughness (profile) — sharp-edged abrasives (steel grit, aluminum oxide) provide more aggressive roughening, while round-grain media (glass beads, steel shot) deliver a smoother surface finish.
Related Consumables: Steel Grit (fast and economical roughening, dirt/rust removal), Aluminum Oxide (high hardness, sharp edges, fast surface preparation), Stainless Steel Grit (for corrosion-sensitive materials, without leaving corrosive residue).
