Sandblasting · Surface preparation

Prepare metal surfaces properly through sandblasting — for a paint job that lasts

Sandblasting doesn't just clean: it removes rust and old paint and creates the anchor profile (the roughness) the new paint needs to adhere and not peel.

Paint applied to a superficially cleaned surface peels within a few months — because it has nothing to grip onto.

A paint job lasts exactly as long as the surface was well prepared. If the rust, oxide and old paint are not removed down to clean metal — and if the surface stays glossy, with no profile — the new coating has nothing to grip onto and peels within a few months.

Sandblasting solves both at once: it removes contaminants down to clean metal and creates the anchor profile (the roughness) the paint needs for durable adhesion. The abrasive and pressure are chosen to suit the material, from fine parts to thick steel or car bodies.

Below you can see the mechanism, the recommended equipment and what proper preparation means for the durability of the work.

Consequences

What happens without proper preparation

  • ! The paint peels and rust appears underneath
  • ! Redoing the work — wasted time and material
  • ! Advanced corrosion under the paint layer
  • ! Uneven appearance and poor adhesion
  • ! Lost warranty on coating work

The solution

How sandblasting prepares the surface — cleaning + profile

Abrasive projected under pressure removes rust, paint and oxide down to clean metal, then creates a roughness profile (anchor pattern). This micro-texturing is exactly what allows the paint or coating to bond mechanically and last over time.

Frequently asked questions

What we get asked most

Why is sandblasting needed before painting? +
Because paint needs a surface that is both clean AND rough in order to bond mechanically. Sandblasting removes rust and old paint and creates the anchor profile — without it, the coating peels.
Does sandblasting damage thin parts? +
No, if the abrasive and pressure are chosen correctly. For fine parts, gentler media and reduced pressure are used; for thick steel, more aggressive media.
Can I also sandblast car bodies? +
Yes. Sandblasting is used to remove rust and paint from car bodies before repainting — with parameters adapted so as not to warp the sheet metal.
