A key step that creates "mechanical tooth" (roughness) so new paint can bond effectively.
Sanding Blocks & Sandpaper: Manual abrasives ranging from coarse grits (60–80 grit for heavy stock removal) to fine grits (180–220 grit for final smoothing).
Orbital & Detail Sanders: Power tools that sand surfaces evenly without leaving deep swirl marks.
Angle Grinders / Scarifiers: Heavy machinery equipped with diamond or abrasive wheels to level concrete surfaces, grind down weld seams, or strip thick coatings.
Abrasive Blasting Equipment (Sandblasters): Uses compressed air to propel media (grit, garnet, or glass beads) against metal or concrete for high-volume rust and scale removal.
