Even though lead-based paint has not been used for nearly four decades, many standing, inhabited structures are still covered with multiple layers of this dangerous substance. Safe removal includes protecting nearby residents from the toxic residue disturbed during the cleanup process, including unhealthy airborne dust. Sponge blasting achieves that goal without the billowing clouds, disruption and noise that accompany traditional 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.
Sponge media make this possible. They are actually tiny, water-based polyurethane bits that contain different strengths of abrasive material. When shot under high pressure onto a surface, their unique chemical consistency actually collects and surrounds fragments of surface paint or rust. Sponges absorb the environmentally harmful substances, which can later be chemically removed, and the media recycled. Disposal is consistent with current EPA standards.
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.
This method excels at suppressing nearly all the dust generated using harsher processes. Sandblasting initially costs less, primarily due to easy availability of materials. It is harder to precisely control during operations, however, and can lead to surface damage if great care is not exercised. Not only do sponges eliminate most residual dust clouds, but they also trap contaminants, and allow precision depth control.
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 end result is decreased emissions, and a higher initial quality of surface preparations. Contractors face fewer fines based on environmental regulations, and the surrounding community is generally less hostile to the disruption. Compared to traditional methods, setup is less complicated, the results are contained more readily, disposal problems are simplified, and the overall job can be finished quickly and efficiently.
