Seeing The Benefits Of Sponge Blasting

By Essie Osborn


There is a new method of cleaning paint and corrosion off buildings and other structures that uses a non-polluting substance that is also reusable. This new process is also virtually dust free when in use. Sponge blasting can etch, remove coatings and clean several substrates and is reportedly superior to customary methods used to date for this process.

This process propels water based polyurethane foam particles at the surface to be cleaned. The particles contain abrasives that break through the surface coverings without damaging the original surface. The five levels of abrasive range from a very mild abrasive to steel grit. They handle the most fragile of surfaces to the toughest rust in record time.

The lowest abrasive level of grit is used for oil removal from hard substrates and heavy machinery. It will not damage hoses or fittings on the machinery. It also works well on smoke and soot removal from concrete and steel structures. The other four levels contain components that rise in intensity with the most abrasive being steel grit that is used for heavy rusted structures or where multiple heavy coatings present the need for a deep profile system.

One of the best features of this process is that the media will be recycled on the spot and used to continue the removal process. It has been recycled up to seven times and the waste product is not toxic waste and is containerized and taken to the city dump. The water usage is also very low and there is very little dust created during the procedure.

By choosing this technique of surface cleaning the customer saves money because labor costs are reduced. By not needing a lot of preparation or clean up time the workers can concentrate on the job at hand. The actual process is much more efficient than sand blasting and can cover two to three square feet a minute. This can cut the working hours in half on an average job. The recycling of materials will also cut the costs not only to the customer but also to the contractor.

The buildings and structures that employ this method of cleaning do not need to stop doing business while work is in progress. There are no chemicals used and the dust and pollutants that normally would be air borne are absorbed by the polyurethane foam on impact and waste water is minimal. All of these factors work to keep the health and safety of the workers and employees at the fore front of the operation.

This procedure is so advanced it can remove single layers of paint or dirt without damaging the substrate beneath. It undoubtedly is the preferred method for historical buildings and private homes. The process is so precise that it could be used around and near sensitive control systems. It is capable of removing man made coverings as well as those created by nature or the environment around the building. This process is very good for removal of patina from metals without damaging them.

This new process of cleaning large surfaces is perhaps the biggest step forward in this field for decades. Not only is it environmentally safer it can save both the customer and the contractor valuable time and money. The cost effective use of labor and materials is made even better by the use of recycling and product safety.
