Dry ice can strip paint — but at typical industrial pressures it doesn't, and that's almost always the answer customers actually want. The most common reason a buyer asks 'does it remove paint?' is that they want to clean a painted asset without damaging the paint underneath. That's exactly what dry ice is built for. If you genuinely want a coating off, dry ice can do it under specific conditions — but it's rarely the most cost-effective tool for that job.
When dry ice preserves paint (the usual ask)
At normal blast pressures (60–140 PSI with 3 mm pellets), dry ice removes grease, soot, mold release, food residue, and similar contamination off cured paint without disturbing the paint film. Pellet hardness is below that of cured industrial coatings. This is why dry ice is the go-to for cleaning painted fleet equipment, food-plant machinery, restoration of fire-damaged painted surfaces, and decal-protected vehicles.
When dry ice will strip paint
- High-pressure setup (250+ PSI) with aggressive nozzle geometry
- Poorly bonded coatings — failing primers, lifting house paint, soft latex on metal
- Carbon-built-up paint layers where the heat embrittles the bond
- Thin powder coats on textured substrates, with the right approach angle
When dry ice is the wrong tool for paint removal
- Well-bonded automotive or industrial coatings on smooth steel — sodablasting or media is faster
- Bridge or structural steel paint — abrasive media is the spec'd method
- Lead paint — abate per OSHA 29 CFR 1926.62; dry ice doesn't capture pigment for disposal
- Multi-layer epoxy or polyurea — chemical strip or media is more economical
The middle ground: selective stripping
Where dry ice shines on coating work is selective removal. Logos and graphics off otherwise good paint. Adhesive residue from old decals. Failing topcoat on otherwise sound primer. Carbon char off paint that's mostly recoverable. These are the jobs that media would over-blast and chemical strippers would damage.
How to brief a quote
Tell us what you want the surface to look like, not the method you think you need. 'I want this conveyor cleaned of food residue without losing the equipment paint' is a perfect dry-ice job. 'I want this paint off down to bare metal for recoating' is usually a media job, and we'll tell you so on the site walk and refer you out.
