Dry Ice Blasting

Dry ice blasting safely removes dangerous mould and more

Dry ice is a perfect option for people looking for environmentally friendly and non-aggressive cleaning methods.

What Is dry ice?

Dry ice is frozen carbon dioxide, a normal part of the Earth's atmosphere. It is the gas that is exhaled by mammals and absorbed by plants and trees. It is also the same gas commonly used when making soft drinks and soda waters.

Dry ice in the past has been used for many purposes, primarily freezing and keeping things frozen due to its extreme temperature. Dry ice is simple to handle with the use of insulated gloves.

Dry ice blasting with pellets

Dry ice blasting is similar to sand or soda blasting: a granular substance such as sand, soda, or dry ice explodes outward in a pressurized air stream to impact a surface to be cleaned.

But that's where the similarities end.

Instead of using sand or other abrasive media to clean the surface, dry ice blasting uses soft dry ice that sublimates (turns into a gaseous state) on impact. The dry ice pellets create mini explosions that lift the unwanted material from the underlying substrate.

Moreover, because dry ice sublimates on impact, there is no cleaning media to remove, as there is with sand. Only the material that was removed must be cleaned up.

Mould remediation with dry ice blasting

Dry ice blasting is quickly establishing itself as the favoured method of mould remediation. It is superior to cleaning mould compared to traditional remediation techniques because it removes the microscopic layer below the surface on which the mould is growing. This allows the abrasion to scour off spores and discolouration left behind.

By eliminating that layer beneath, dry ice blasting eliminates up to 99.999% of the mould spore and other organic contaminants from the surface.

Applications for dry ice blasting

At DKI-Pro Pacific, we favour dry ice blasting for many applications, such as:

• Fire remediation
• Graffiti removal
• Grease and oil removal
• Removal of most adhesives

Advantages of dry ice blasting

• Jobs completed faster
• Safer and cleaner
• Environmentally responsible
• Surface is left completely dry
