Concrete Surface Ice Blasting
Concrete Surface is one of the jobs dry ice blasting was made for. We clean it without water, without chemicals and without anything abrasive touching the surface.
What builds up, and why it matters
On this kind of work the problem is grease, soot, mildew staining, old finish and garage grime. Household surfaces are usually softer than industrial ones, so the non-abrasive part matters more, not less.
We come to the house; the rig runs off the driveway. The people who call us about concrete surface are usually homeowners and collectors, and the thing they are actually worried about is damage to something in your own home.
The method
Why dry ice and not the alternatives
- Non-abrasive
The pellet is soft and sublimates on impact, so the work is thermal rather than mechanical. Machined faces, plating, paint and gaskets survive it.
- Low moisture
No standing water in a harness, a bearing or a cabinet, and no dry time before the equipment goes back into service.
- No secondary waste
Sand, soda and walnut shell all have to be swept and hauled. Dry ice leaves only the contaminant it removed.
- Often no teardown
Much of this work is done in place, which is usually where the real saving is. The labor is in the disassembly, not the cleaning.

Questions we get asked first
Will it damage the surface underneath?
On most substrates, no. The pellet is soft and sublimates on impact, so it does thermal work rather than mechanical work. We still test an inconspicuous spot first on anything unusual.
Do you have to take the equipment apart for concrete surface?
Usually far less than you would expect, and often not at all. Cleaning in place is where most of the saving comes from, because the labor is normally in the teardown and reassembly.
How much mess does it make?
Far less than the alternatives, because the blasting media disappears. What is left is the contaminant itself, which we contain and clean up.
Do you come to us?
Yes. The whole rig is mobile. Compressor, hose and operator arrive at your shop, plant, driveway or dock, anywhere across South Florida from Miami out to roughly a hundred miles.
What does a job cost?
It depends on the equipment, the contaminant and the access, so we will not throw a number at you over the phone without understanding the work. Describe the job and we will give you a real figure.
How soon can you look at it?
Send photos and a short description and one of the owners gets back to you. If you have a shutdown or a deadline, say so up front and we will tell you honestly whether we can hit it.
The comparison
Why not just pressure wash it
- Solvent and degreaser
Chemistry works, but you inherit ventilation, waste handling and a film on the surface.
- Hand scraping
Slow, inconsistent, and the tool marks the surface. Fine for a small area, unworkable across a machine.
- Media blasting
It takes the top off whatever it touches. That is the point on rusted plate and the problem everywhere else.
- Pressure washing
Water gets into everything and has to come out again before the equipment runs. Around electrics it is off the table entirely.
- Dry ice
Thermal shock breaks the bond. The pellet sublimates, so nothing abrasive touches the part and nothing is left to collect but the contaminant.
What comes off
What comes off, and why
If it is bonded to the surface rather than part of it, there is a good chance this takes it off. The list below covers most of what we are called out for.
- Ink and printing residue
Dried ink on precision roller faces, cleaned without altering the cell structure that does the work.
- Food residue
Carbonized product build-up in a plant where neither standing water nor a chemical film is acceptable.
- Grease and oil
Oil film is the layer everything else sticks to. Remove it and half the job is already done.
- Carbon and soot
Baked carbon on a manifold, oven or weld fixture. Thermal shock is exactly the wrong thing for the bond holding it on, which is why this works.
- Adhesive and sealant
Cured sealant, old gasket, tape glue and sound deadening, the residue left when something was removed but its bond was not.
- Resin and mold release
Release agent and resin build-up on tooling, where a solvent fix trades one residue for another.
- Paint and coatings
Removed selectively where the substrate underneath has to survive, which rules out most abrasive approaches.
How a job runs
Nothing about this should be a surprise
Nobody should have to guess what they booked. This is every stage of a job in the order it happens.
- You look before we pack up
We would rather you find the missed spot while we are standing there than a week later. Another pass on the day is the cheapest fix available.
- You describe the job
Tell us the machine, the mess and the constraint. A couple of photos answers more than a long description, and if the honest answer is that something else suits it better, we say so.
- We look at access and containment
Where the compressor sits, how far the hose has to reach, what gets masked or moved, and where the removed contaminant ends up. On food and electrical work this is most of the planning.
- We test a small area
Pressure and pellet size get dialed in on an inconspicuous spot before we touch anything visible. Painted parts, soft alloys and older finishes all behave differently, and the right setting on one is the wrong setting on another.
- We blast, then clean up
The ice is gone on impact. What is on the floor afterward came off your machine, and clearing it is ours to do.
What to expect on site
The part will be cold when we finish. Sometimes that means a short wait before handling; sometimes it means a film of condensation as it warms back up.
Everything the rig needs arrives with it. No tap, no drain, no outlet.
Anything nearby that should not be touched gets masked before we start. That is quicker than explaining it afterward.
Dry ice is carbon dioxide in solid form. It is non-toxic and leaves no residue, but it does displace oxygen in an enclosed space, so ventilation is part of the setup rather than an afterthought.
Send us the job.
Tell us what the machine is, where it is and what is on it. A photo or two speeds it up. One of the owners calls you back.
