Lead-based paint formulas have been unavailable for over four decades, but there are still many standing structures bearing multiple coats. Part of the cleanup and removal process involves shielding nearby residents from the toxins that become airborne, primarily paint fragments and dust. Sponge blasting can accomplish that without the noise, disruption, and choking clouds that can accompany other commonly used scouring methods.
The technology is safe for use on most hard surfaces, vulnerable or easily damaged layers of substrate, and even some types of industrial equipment. Although this method is frequently compared to scouring processes using high pressure streams of water, other abrasives, or plain sand, it is a step ahead of them. While abrasives are still part of the equation, they are managed more easily, cause less damage, and little environmental harm.
The process relies on sponge media, which consists of small, water-based polyurethane fragments that have been impregnated with different abrasives. These particles are shot pneumatically onto a surface, where their chemical structure allows each to collect some of the substance being removed. The media absorbs that material, which can then be safely removed from the sponges, and disposed of according to current 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.
Media designated Brown is best suited to removing flaking paint, or eliminating light surface rust along with lighter industrial coatings. White is the right strength for getting rid of the latest building graffiti without additional damage, and is effective on tile, composites, or even fiberglass coverings. The least abrasive is Green sponge media, perfect for eliminating grease or soot in awkward places hard to reach by hand.
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.
Individual sponges can be cleaned and recycled, making them even more cost effective. The machines that pressure-spray these particles are quieter than other types of blasters, and make it possible to complete jobs in crowded urban locations without forcing adjacent businesses to close down for the duration. In some cases, employees can remain inside while work continues on other floors.
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.
