What Is Sanding?
Sanding is surface preparation that uses abrasive material to remove loose paint, smooth rough areas, and create a cleaner surface for the next coating. The process may expose sound material, soften sharp edges, or remove residue after paint stripping. Proper sanding helps new primer or paint bond evenly.

Key Takeaways About Sanding
- Sanding changes surface texture through controlled abrasion.
- The abrasive choice depends on the material and coating.
- Sanding isn't the same as stripping all paint.
How Sanding Works
Sanding uses abrasive paper, pads, or tools to cut down high spots and remove weak material. The goal may be a smooth surface, a dull finish, or a gradual edge between bare and painted areas. The surface material guides the abrasive choice.

During a paint stripping service, sanding can follow chemical or mechanical paint removal. The work removes remaining flakes and smooths transition lines. The surface is then checked for dust, loose fibers, and rough patches. Paint adhesion depends on a clean, sound surface with a texture that suits the next coating.
Surface Check
- Wood may need light sanding to smooth raised fibers.
- Metal may need careful sanding around rust or old coating.
- Previously painted surfaces may need edge sanding before primer.
Expert Note
When we sand during paint stripping, we match the abrasive method to the surface and remaining coating. We check edges by hand so they feel gradual, then remove dust before the next preparation step. Our team also watches for soft wood, exposed metal, and areas that need separate repair.
Sanding in Practice: A Real-World Example
A homeowner may have peeling paint on an exterior trim board. During paint stripping service, we remove the loose coating, sand the remaining edges smooth, and prepare the sound surface for primer.
