Amélia Dionísio at 90 Segundos de Ciência: Graffiti in Monuments- The faster the cleaning, the lower the damage

Amélia Dionísio presented her project, concerning the study of graffiti (as an act of vandalism) and the stone used in the cultural heritage. In this project, an SO2-rich urban atmosphere, simulated in a laboratorial climatic chamber, was applied to graffiti painted stone samples (spray paints). After the exposure, different cleaning technologies we applied and various laboratory methods were used to study: a) the aging processes of graffiti paints and their interaction with stone and b) to optimize the cleaning processes of these aged graffiti.

European Union’s Cultural Heritage is being celebrated during this year and one of the aims of the Agenda 2030 (proposed by the UN) for Sustainable Development is the strengthen the protection and safeguarding of the heritage.

This project was partly financed by Fundação Calouste Gulbenkian.
