Historic stone facade cleaned of graffiti and weathering by laser

Historical Stone Building Restoration success story

Graffiti, weathering stains and biological growth had to be removed from stone facades.

The customer

A historical building restoration team

The challenge

Pressure washing caused water intrusion and runoff pollution; chemical cleaners risked discolouration or etching.

The solution

We deployed our Trolley Laser Cleaning Machine — a 100W–300W machine — with parameters established on the customer's own material before installation.

“The laser restored the stone beautifully without harming its historical integrity.”
