For precise, material-friendly cleaning
Historic buildings, sculptures, fountains, or façades are valuable cultural assets. Over time, however, weathering, air pollution, algae, moss, or previous renovation measures can take a heavy toll on them. Professional cleaning and surface preparation are therefore essential to preserve their aesthetic impact, historic fabric, and long-term stability.
In heritage conservation, abrasive media enable precise, material-friendly cleaning. They remove soiling, loose particles, or old coatings without damaging the material’s substance. They also prepare the surface optimally for protective measures, conservation, or restoration.
Why abrasive media are indispensable in heritage conservation
The requirements for blasting processes in heritage conservation are particularly high: historic materials must be treated gently, structurally protected, and cleaned with precision. Abrasive media fulfil several functions in this context:
Dust, soot, algae, moss, graffiti, or old coatings must be removed reliably.
The historic fabric and sensitive materials such as sandstone, limestone, or wood must not be damaged.
After cleaning, protective coatings, impregnations, or restoration materials adhere better.
During blasting, the requirements of heritage conservation and restoration guidelines must be complied with.

Benefits of using abrasive media in heritage conservation
- Effective removal of soiling, graffiti, and deposits
- Gentle cleaning of sensitive, historic materials
- Optimal preparation for conservation and restoration.
- Preservation of the substance and structure of listed objects
- Sustainable care and long-term protection of historic buildings.
Tips for using abrasive media in heritage conservation
You should only treat soft and sensitive materials with gentle abrasive media.
Excessive pressure can damage historic surfaces, while too little pressure does not remove soiling sufficiently.
Historic buildings often require scaffolding or mobile elevating work platforms. Personal protective equipment is mandatory.
On damp surfaces, blasting can lead to pore damage, while dry materials deliver better results.
After cleaning, surfaces should be conserved, impregnated, or protected to preserve the substance in the long term.
Residual abrasive media and loosened contaminants should be collected and disposed of properly, especially in urban or protected heritage areas.
