Although lead-based paint has not been available for over forty years, there are still thousands of buildings covered with multiple layers of that toxic coating. When paint or other industrial coatings must be removed, protecting nearby occupants from the clouds of dust generated by that process is a priority. Sponge blasting can achieve that goal without creating toxic dust, noise, and the disruption that accompanies sandblasting.
Used for industrial scouring as well as paint removal, this new process can be effective on several types of materials, including hard surfaces, easily damaged substrate layers, and even on some types of heavy equipment. The process is commonly compared to those using sand, abrasives, or high pressure water, but is actually more advanced. The abrasives used are much more easily managed, cause less damage, and are environmentally safer.
The primary ingredients are tiny, water-based polyurethane fragments containing various forms of abrasive grit. They are propelled at high speed onto the cleaning surface, and the impact allows their particular chemical makeup to instantly collect and surround fragments of detritus. They actually absorb the paint or grime, which is later removed from the sponge, and disposed of in an environmentally safe manner.
The most common abrasives are included in five basic categories, and are color coded according to the function they best perform. Red sponge media contains steel grit, and is ideal for cutting through industrial coatings. Silver contains aluminum oxide abrasives for targeting paint and other hard coatings, as well as pre-conditioning surfaces for petrochemical and paper production companies.
Flaking coats of old paint and lighter industrial sealers are easily removed using Brown media, which is also effective against surface rusting. The White variety is commonly used by store owners to eliminate building graffiti, and can be used on composites, tile, or fiberglass. Green sponge media is the lightest abrasive, and is employed mainly to get rid of soot and grease deposits in places hard to reach with normal cleaning tools.
Unlike traditional scouring processes, this system creates little dust. Sandblasting is somewhat less costly due to wide availability and lower media cost, but is more difficult to precisely control, making surface damage a real possibility. Not only do the polyurethane sponges prevent dust clouds from forming by trapping loosened contaminants, but they allow much greater accuracy of operation.
Scouring media is reusable multiple times after being cleaned, and recycling is economical over time. The machines that shoot these particles onto surfaces during cleaning are far less noisy and intrusive. In many cases, this cleaning process makes it possible to finish jobs in high density urban locations without forcing co-located businesses to suspend activity, and is also safer for nearby residents.
The final result is higher quality surface preparation, and safer emission levels. The local community greatly appreciates fewer interruptions, and contractors using this method often face fewer fines for breaking environmental regulations. When compared to other scouring methods, the setup is less involved, waste is more readily captured and safely eliminated, and the job completed both efficiently and quickly.
