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.
