Façade cleaning using dry ice blasting for monument restoration in Prague

Type of measure: Substitution

The restoration of well-known historic monuments in Prague included façade cleaning using dry ice blasting. Technical experts, architects and historians were pleased with the results and with the working conditions of the restoration teams.

Façade cleaning is usually performed with chemicals or by using blasting with various media. Chemical cleaning is often done with hazardous substances like dichloromethane or methyl pyrrolidone. Sandblasting is hazardous due to the crystalline silica, a carcinogen. Using dry ice blasting may be a safer alternative.
