Preserve History – Protect What’s Important
Sponge-Jet provides professionals with a dry, low-dust, micro-abrasive composite to clean multiple substrates across many applications.
- Removal of environmental contaminants
- Historic structures & monument rehabilitation
- Graffiti removal
- Lead paint remediation
- Efflorescence & exfoliation
- Soot, char & smoke damage
- Stone & marble cleaning
Materials can be selected that can remove contaminants without damaging the surface. This controllable system allows the operator to adjust pressures and media rates to match the needs of the project. The low rebound nature of Sponge Media prevents damage to adjacent surfaces, while the low dust feature enables the operator to visually watch and control contaminant removal during the process.
Testimonials
“In terms of preservation, graffiti is among the bigger problems we face on the wall because it’s fragile sandstone. In the past, we’ve had to use chemicals… Now, we have available gentle abrasive measures.” - Christina Wallace, Senior Preservation Conservator, Presidio Trust
“It had the advantage of keeping all of that lead contained. And they had worked out a process for cleaning the lead out of the sponge and then reusing the sponge. So we could get up there and remove the lead completely, and very easily." - David Kemnitzer, Preservation Director, Powe Jones Architects
