Sandblasting

If you have a need for sand blasting, call on the services of EMS.

Typically, sand blasting including concrete sandblast finishing / exposed aggregate finishing involves cleaning or etching a surface by bombarding it with fine particulates propelled at high velocity. The particulate may not be sand, either. These days it actually could be steel grit, copper slag, powdered abrasives – even walnut or coconut shells! Sand was replaced because prolonged inhalation of its dust can cause silicosis, a serious, often deadly lung disease. Of course, inhaling any kind of dust can be dangerous, so sand blasting – regardless of the particulate used – should always be a carefully controlled process. An alternate air supply, protective clothing, and proper ventilation are essential. So too is effective containment. This must be built to collect dust and contaminants for proper disposal and protect non-involved bystanders as well as property.

The primary tools of sand blasting are an air compressor, a blaster nozzle, and the particulate, or abrasive, itself. These may be applied in one of two distinctly different ways:

  1. more broadly, to clean a surface of especially ground-in dirt or anything unwanted that may be clinging to it, or
  2. more finely, to etch words or graphics into glass or some such material. (In this case, two other pieces of equipment are needed: a workstation to hold the piece to be etched in place and a collection chamber for the excess dust.)
