FREQUENTLY ASKED QUESTIONS
Dustless blasting is an innovative and environmentally friendly way to return surfaces to their original condition, clean of paint and buildup, without any damage to the original surface. Unlike traditional dry blasting, it doesn’t produce dust or pollutants and it’s much more effective than power washing. The wet blasting process reduces heat and friction, so it prevents warping on materials that are hard to restore otherwise. It’s the perfect solution for paint stripping, rust removal and to restore a variety of surfaces to like-new condition.
Dustless blasting uses a combination of water, recycled abrasives and compressed air to achieve a high-powered cleaning force. Instead of releasing dust into the air, it releases only water vapor. This allows a safe environment even while cleaning is going on. It’s only incredible fast and effective, leaving virtually no trace of prior paint coats, debris or dirt buildup. You can watch the years come off right before your eyes.
Dustless blasting suppresses the plume of dust by encapsulating the dust in water, allowing us to work almost anywhere with minimal containment. This water containment reduces dust by approximately 92%.
Our system can use any kind of abrasive media that sinks in water. We generally use a high-quality crushed glass or garnet. It’s clean, free from harmful silica and chemicals and versatile. We choose to use materials that are inert, so both our abrasive and rust inhibitor are friendly on the environment.
The dustless blaster will NOT cause warping because friction and heat are reduced by the water. Warping occurs when sheet metal heats up due to friction from dry abrasives. In fact, the temperature of the metal being blasted is usually REDUCED by about 10 degrees from ambient.
Our wet blast equipment will remove the toughest coatings yet can be adjusted to clean the most fragile surfaces, without embedment or damage. Whether removing corrosion on structural steel or removing graffiti from sandstone, wet abrasive cleaning is extremely versatile.
Glass and chrome can be damaged by any kind of abrasive blasting. You should always mask off or remove chrome and glass prior to blasting.
We use an environmentally friendly rust inhibitor in our blast and wash down water, once dry you should treat it like bare metal. It can be stored in a dry environment for several days without rusting, for best results we recommend priming within 72 hours.
Dustless blasting is significantly cleaner than conventional sandblasting, however, some blast media residue is created. By laying down drop sheets or plastic at the base site, the majority of this media will then be captured as it falls to the ground leaving you with minimal clean up.
No, once we have pressure washed with rust inhibitor mixed with water, nothing is left, not even the rust inhibitor. Once the surface is dry the surface is ready for paint.
Dustless blasting using crushed glass is very effective on hardwoods only. Even soda will damage softwoods. Once again it depends on how hard the coating you are removing is as to whether the timber underneath will sustain any damage. We can gladly blast a test piece to establish the final result prior to beginning work.
Because blasting is generally accompanied by a paint process, most blasting operations are conducted during warmer seasons. However, if required, dustless blasting can be carried out during the winter months by adding alcohol to the water tank and using other precautions.
Although the dustless blasting process can produce sparks, these are classified as “cold sparks”, which are not capable of igniting flammable gases. This is because the water used in the dustless blasting process dissipates static electricity, effectively preventing the type of spark which can cause combustion.
Dustless blasting can be used on flammable sites where other methods of surface preparation are not permitted. This is because the “cold sparks” produced by dustless blasting are not capable of igniting combustible atmospheres.
Several independent studies conducted by unbiased third parties have confirmed this. Reports done by Thornton Laboratories, Shell Research Ltd, UK and Bradley, National Safety Council Congress, USA show the same results, even with a wide variety of abrasive and combustibles.
“Cold sparks” are produced by friction, whereas the type of spark that can ignite a combustible atmosphere is caused by static electricity.
Many other independent studies and real-world jobs have confirmed that no static electricity build-up occurs during the dustless blasting process. This is because the water used in the process creases a natural ground which prevents static electricity. It should be stressed that during dry blasting operations, measures must be taken to prevent the build of a static charge.
Our focus is primarily on the East and West Kootenay’s of British Columbia as well as Southewest Alberta. We will however travel outside this area for larger contracts.
