What are the pros and cons of using shotblasting to remove a coating system from a concrete floor?


Selected Answers

From TATIANA FEDOROVA of AOTCC on February 4, 2011:
In my 15-years experience I have found that  sandblasting in some cases doesn't work at all, especially if you have to remove thick coatings, even those as soft as asphalt. Shotblasting doesn't work properly if you have to remove thick (4-6 mm) and hard epoxy or PUR floorings. I use for this purpose scarifying machines (for example, Von Arx), 200 mm wide  for thin coatings, 300-350 mm wide  for thick. If you use a good vacuum cleaner, you have practically no dust.

From Lee Edelman of Independant on January 28, 2011:
Using a shot blast system peens the surface and does not give an angular profile. Also, it will not get close to edges. You can damage the concrete if close attention is not given to the process.

From remko tas of Futuro SRL on January 24, 2011:
Shotblasting compared to sandblasting on a coated concrete floor will generate a lot less dust. But the shotblasting system will likely be done with a portable wheelblaster and recovery unit. This way, you are not able to see when the coating removal has finished and when the abrasives start to eat away the concrete surface, creating in this way an irregular base. Before application of the next coating, you may have to fill up the holes, which may be costly. Using an alternative wet sandblasting unit or a high-pressure (hot water) jetting machine can reduce this damage as the operater keeps the lance in a place only until he removes the paint and will then move on.
