Sponge-Blast is Fast, Clean, and Dry!
Sponge Blasting adds speed and decreases dust in the removal of paint and coatings when compared with more traditional preparation methods. This new technology offers PennFleet the ability to remove individual layers of coatings with no damage to the surface beneath.
Sponge-Blast technology is so advanced that we can remove finite layers of paint, grime, or other coverings without damage to the substrate beneath. This system is often used on historic buildings and homes, and is the industry choice when precision is required. Sponge-Blast is even safe for use around delicate control systems.
Other removal systems cause dangerous particulate emissions or fumes from chemicals, and make a big mess. Because the Sponge-Blast system uses a sponge abrasion method, your ability to use your business or home is unhindered. There is no moisture, harmful fumes, nor air quality concerns to contend with. The sponge media is recaptured for re-use so it is clean and environmentally friendly.

The Sponge-Blast Process
Sponge Media is an open-celled, water based polyurethane impregnated with abrasives. As a result it has several inherent cost, time and money saving benefits. The pliant nature of Sponge Media allows its particles to flatten on impact exposing the abrasive. After leaving the surface, the media constricts pulling and encapsulating what would normally have become airborne contaminants.
Sponge-Jet’s Sponge Blasting System™ consists of the Sponge-Jet Media Feed Units, Sponge-Jet Media Classifiers and a variety of different Sponge-Jet Sponge Media designed to offer a dry, low dust, low rebound, reusable abrasive or non-abrasive surface preparation system.
Sponge Media is poured into a Blast Feed Unit where it is mechanically stirred and fed into a rotating screw-auger port at the bottom of the pot. The auger entrains the sponge in a variable pressure air stream – and the air-media mix flows through a hose and venturi blast nozzle to impact the work surface at 15 to 100 mtrs (50 to 325 ft.) per second depending on the blast pressure. On impact with the surface the sponge particles compress and slide across the surface producing a scrubbing and cleaning action, more similar to a sanding effect eliminating the more harsh and dusty negative effects associated with conventional grit blasting. The abrasive rebounds at quite low velocity as the media converts the majority of its energy into work at the surface. For most projects a tarpaulin or light plastic sheeting around the work area will contain media for pick-up and recycling. The Sponge Blast media will generate less than 10% of the airborne dust levels normally experienced with conventional grit blasting medias. This is a key Health and Safety benefit when removing lead and chromate paints. The Media Feed Unit requires a 7 bar (100 psi) air supply – capable of supplying clean dry air at 6 to 10m3/min (210 to 353 cfm).
Other removal systems cause dangerous particulate emissions or fumes from chemicals, and make a big mess. Because the Sponge-Blast system uses a sponge abrasion method, your environment is virtually undisturbed. There is no moisture, harmful fumes, nor air quality concerns to contend with. The sponge media is recaptured for re-use so it is clean and environmentally friendly.
