Sandblasting & Abrasive Blasting

Abrasive blasting removes rust, mill scale and old coatings and establishes the surface profile a coating needs to bond. Proper prep — not the paint — is what determines coating life.

What abrasive blasting achieves

Abrasive blasting removes rust, mill scale, old coatings and contaminants, and establishes the anchor profile a new coating needs to bond. It is the foundation of every protective coating system — and the step most responsible for how long that system lasts.

SSPC / NACE surface-prep grades

Surface prep is specified to a standard grade, not "as clean as possible." The common grades (SSPC, now under AMPP; NACE equivalents in brackets):

GradeNameTypical use
SSPC-SP 7 (NACE 4)Brush-off blastMild exposure, over tight rust
SSPC-SP 6 (NACE 3)Commercial blastMost atmospheric coatings
SSPC-SP 10 (NACE 2)Near-white blastImmersion, aggressive/marine service
SSPC-SP 5 (NACE 1)White metal blastMost severe / critical service

The higher the grade, the more material removed and the more labor and abrasive — which is why the specified grade drives cost.

Abrasive & profile

Garnet, coal slag, steel grit and other media each produce a different surface profile (typically 1.5–4 mils). The coating system dictates the target profile; blasting is set up to hit it consistently and verified with profile tape.

Industries we serve

Refineries and petrochemical, structural and bridge steel, tanks and vessels, manufacturing and fabrication — anywhere steel must be prepped to a coating spec.

Common questions

What SSPC surface-prep grade do I need?
It depends on the service. SP 6 (commercial blast) suits most atmospheric coatings; SP 10 (near-white) is standard for immersion and aggressive environments; SP 5 (white metal) is for the most severe service. Your coating's data sheet specifies the minimum grade.
What is surface profile and why does it matter?
Profile is the roughness (anchor pattern) blasting creates, typically 1.5–4 mils. Too shallow and the coating won't grip; too deep and peaks may not be covered. The coating system dictates the target profile.
Do you handle containment and disposal?
Yes — vetted contractors provide environmental containment and dispose of spent abrasive per regulations, which matters near occupied or sensitive sites and is priced into the quote.
