Before treatment / general view: sculpture is heavily stained by a permanent anti graffiti coating. Conspicuous joint (repair) at the lower corner.
 

Before treatment / detail: surface is badly weathered and shows extensive damage (pitting).

After treatment / general view: a combination of steam and solvent cleaning was applied to minimize the layer of anti graffiti. Previous joint repair (mortar) was removed and surface losses were in filled and colour matched. This is a reversible process that can be undone if necessary.
