Graffiti removal from Limestone
Pmac were called upon by Stone Systems Ireland to clean all the Asian black limestone at the newly erected IDA building in Waterford.
The client was concerned this surface could be a target for graffiti in the future. Generally, the only way for graffiti removal from Limestone is by using chemicals – and this limestone would be damaged by the use of any harsh chemicals or acids.
P Mac therefore advised that the best solution was to coat the surface with an anti-graffiti sealer. This would mean that any paint could be removed using hot water and Stone Soap if necessary. We initially cleaned the facade by padding it with P Mac Stone Soap, and then we hot washed the entire facade. Once dry, we applied two coats of anti-graffiti coating. The client was very happy with the outcome.
Pmac is strongly committed to sourcing the best anti-graffiti products on the market as this technology is constantly developing and changing. We examine each site on an individual basis and determine which coating is most appropriate. Once an anti-graffiti coating has been applied, any recurrence can be removed quite simply with water. The application of an anti-graffiti coat saves significant money in the long term.
