Frequently Asked Questions

The questions we answer most, in one place. If yours isn't here, ask a specialist — describing your substrate, standard and environment is enough.

The technology

What is bristle blasting?

Bristle blasting uses a rotating belt of hardened, forward-angled bristle tips that strike the surface and immediately rebound, removing corrosion and coatings while cutting an anchor profile in the same pass — no abrasive media, no containment.

What cleanliness standard does the Bristle Blaster® reach?

A cleanliness comparable to ISO 8501-1 Sa2 ½ & Sa3 (SSPC-SP10/SP5 visual equivalents), depending on belt and technique.

What anchor profile does it produce?

A controllable 65–85 µm (2.5–3.3 mil) Rz profile — also on weld seams, edges, around bolts and in surface irregularities.

How long does a bristle belt last?

Roughly one hour of working time, or about 1 to 1.5 m² of prepared surface, depending on substrate condition.

Can it be used in explosive atmospheres?

Yes — the Bristle Blaster® is ATEX-approved, including with dust control, and works without the spark-producing media stream of abrasive blasting.

How does it compare to sandblasting?

Comparable cleanliness and profile, without loose media, dust containment or a blast yard. For large continuous areas (roughly 5,000 m² and up), conventional blasting may still be more economic; everywhere access, containment or permits are the constraint, grit-free wins on total job time.

Tools & belts

Which tool is right for my job?

Bristle Blaster® for corrosion, coatings and profile on steel; MBX® for lighter coatings, rust and automotive substrates; Vinyl Zapper® for vinyl, stickers and adhesive; Tercoo® for bulk removal of heavy rust and thick coatings; Prepper® robotics for large or hazardous areas. When in doubt, ask us — describing your substrate and standard is enough.

How do I choose the right belt?

Use the interactive Belt Selector, which matches belt type, width and grade to your substrate, cleanliness standard and target profile.

Is there a subsea version?

Yes — the Bristle Blaster® Subsea, developed for underwater surface preparation on offshore and marine assets.

Buying, training & service

Do you offer training?

Yes — hands-on operator training through the Dr. Prepper® Academy (Training), on-site or in Hennef, covering technique, standards and certification.

Can I rent tools instead of buying?

Yes, rental is available for project work — see the Tool Rental page for terms.

How do I buy, and what does it cost?

MontiPower® sells through regional offices and authorized distributors. Request a quote describing your application, or find your nearest distributor — pricing follows configuration and volume.

What about repairs and warranty?

Register your tool for warranty coverage, and use the repair service for maintenance and fixes; spare parts are available for the full range.
