Dry Ice Blasting

Dry ice pellets, when applied under high pressure to a soiled or painted substrate,
cause the surface finish to flash freeze and crack. The pellets then move into the cracks and sublimate creating thousands of small explosions that lift the finish off the substrate.


Dry ice is minimally abrasive with with a Mohs scale hardness of about 2 so it can be
used in delicate situations as well as those that require more aggression.
Once sublimated, the dry ice reverts to its natural state of gaseous carbon dioxide.
Because there is no secondary waste the process is ideal for cleaning machinery that
cannot tolerate grit or areas where the presence of water or other solvents is
unacceptable. Dry ice application is scalable in terms of pressure, rate of ice flow and particle size allowing its effective use over a wide range of situations.


Vapor Blasting

Vapor blasting employs water vapor mixed with a small amount of media under high
pressure. This process is appropriate for applications requiring more aggression than
dry ice but far less than traditional sand blasting. In addition to using a relatively small
amount of media, a major advantage is the reduction of dust from blasting by more than 90%.

As with dry ice, vapor blasting is scalable. This allows us to clean everything from soft
plastic to marble statuary to steel beams. The pressure, grit size and ratio of water to
media can be adjusted to suit specific requirements. An example of this is the ability to
remove soil or paint from brick and block surfaces with little to no degradation of
masonry joints. There are several media options depending on the project. We find
garnet, crushed glass and microcrystalline silica to provide a complete range of abrasion
to work effectively with any job. It is an ideal solution for complete graffiti removal and
other exterior cleaning that creates very little secondary waste with low environmental impact.
