Grit-Free Surface Preparation: Comparable to SSPC-SP10, Without the Blast Booth
Grit-free surface preparation is a mechanical method that removes corrosion and coatings and generates an anchor profile in a single step, without abrasive media. MontiPower's Bristle Blaster® reaches cleanliness comparable to abrasive blasting with a controllable 65–85 µm Rz (2.6–3.3 mil) profile (also comparable to SSPC-SP10), with no grit, no dust and no blast containment.
How grit-free preparation works
Forward-curved bristle tips strike the surface with kinetic energy comparable to grit-blast media, then retract instantly. That impact-and-rebound action removes corrosion and coatings and cold-works a clean, micro-indented anchor profile in one pass: no heat, no smearing, no embedded grit. For heavy build-up, the Two-Step Method pairs Tercoo® heavy removal with the Bristle Blaster® finish.
The standards it meets
Grit-free preparation reaches surface cleanliness comparable to abrasive blasting, with a controllable 65–85 µm Rz (2.6–3.3 mil) anchor profile (up to 120 µm Rz) measured by replica tape to ASTM D4417-C. Digital data tracking provides a traceable audit trail for the most demanding coating specifications.
Where grit-free preparation wins
The further a job is from an open blast yard, the more grit-free wins: ATEX Zone 1 offshore platforms, in-service refineries and tanks, confined spaces, weld seams and field joints, bridges and rail under live traffic, and spot repair where containment is impractical. It is the only hand-held method comparable to abrasive blasting without a blast pot.
