Architects, conservators and engineers need to specify products and methods of surface preparation and cleaning that will maintain the integrity of the surface.
Chemicals may be difficult to dispose, water may be difficult to contain, and ordinary abrasive materials may damage the substrate.
Sponge-Jet’s proven technology is chosen by professionals to precisely clean and remove surface contaminants from sensitive substrates:
Inspectors can observe the surface cleaning in real time for better control of their project—all while protecting the environment.
Sponge-Jet protects the public during a courthouse coating restoration project; It was selected to suppress lead-based dust during complete coating removal from cast iron cornices on the Historic Marion County Courthouse.
Sponge-Jet partners in the safe restoration of the Massachusetts State House; Sponge Media™ abrasives were used to remove multiple layers of lead-based coatings from structural steel beams (adjacent to sensitive glazed white brick ceiling tiles). Removal relied heavily upon the reduced rebound (protecting tiles) and the process’ ability to contain hazardous coating particles at the source of generation.
This historic facade contained multiple stone types, all heavily soiled from years of city smog and acid rain. Here the preservationist easily adjusted for each stone type and was able to clean adjacent to place windows.
Sponge-Jet helped de-paint and clean the exterior of the second oldest Synagogue in the US; the preservation project used Sponge Media™ micro-abrasives to remove layers of failed coating from the building’s various substrates – in doing so the preservation project won the esteemed Carolopolis Award.
This highly skilled team, specializing in remote access technology (repelling from ropes) used White SPOCC Sponge media™ at low pressure to clean environmental staining from the copper roof of the Oakland Tribune Building. Containment debris nets were positioned below as they freely blasted high above the city.
West Point’s Bartlett Hall was the perfect to setting to show Sponge-Jet’s ability to remove efflorescence from the hall’s exterior Olean Granite blocks; even better were the constraints… no moisture… no fugitive emissions and no interruption to ongoing classes and activities scheduled in the building.
The Guilder’s Studio, charged with restoring roof-top decorative copper lanterns on the New York Life Building, chose Sponge-Jet to controllably remove multiple layers of lead paint, provide proper cleanliness and the specified anchor pattern for the sizing primer – ultimately preparing the finals for gold gilding.
The five Torres de Satélite structures were blasted with White Glass Sponge Media™ micro-abrasives to remove badly faded and peeling paint from their concrete substrates, but without damaging the substrate or causing interruption to the thousands of commuters passing the site each day.
Cleaning a Grand Rapids Historic brick building and removing soot and environmental damage from granite architectural headers; see the remarkable before and after results.
Sponge-Jet cleans aged soot/burned coal residue from brick, wood surfaces, ceilings and trusses of historic, 1920 cold-storage building.
The first major restoration of the William Tecumseh Sherman statue includes Sponge-Jet as the primary restoration technology; the bronze statue employed Sponge-Jet to remove the failing layers of guilding and then slightly profile it in preparation for resurfacing.
Restoration contractor uses Sponge-Jet micro-abrasive control to regulate enough pressure with the right Sponge Media™ product to remove the accumulated layers of paint but without appreciable damage to the original brick facade
There was a Sponge Media™ product for every substrate in this historic church where every media equally dissipates collision energy so as not to cause additional damage to surrounding stained glass, icons and wood work.

Brick has been used for the construction of homes and buildings since ancient times. The first known brick was discovered on an archeology site in the Middle East, dating its use back to 7500BC. This discovery means humans started using brick 3,000 years before the invention of the wheel! Similar to the wheel, the materials used to make brick has evolved.Read More >
Corrosion is everywhere - from a speck of rust on a bridge’s bolt to the advanced chemical erosion of a process pump, to blistering paint on a building’s structural steel, fences, and railings. When coatings fail and metal components oxidize, property and infrastructure risk further damage. Corrosion weakens metal from the outside in - untreated metal can rust away completely, leaving behind gaping holes.Read More >
