Graffiti on facades often has a heavy impact in social and economic terms, particularly when historical and artistic artefacts are affected. To limit the damages to the surfaces, preventive plans are implemented and anti-graffiti coatings are used as a protective measure. In this study, the distribution of a spray paint inside a highly porous stone, with and without anti-graffiti protection, wa...

apermanent anti-graffiti clear polyurethane coating, using a silicone additive, was prepared and studied. various techniques, such as contact angle measurements and edx were employed to characterize and investigate thesurface properties of the coatings. the results revealed that with inclusion of silicon additive to clear coating, according to wu method, surface free energy was decreased from 4...

11 Abstract 12 13 Coating building materials with anti-graffiti treatments hinders or prevents spray paint 14 adherence by generating low energy surfaces. This paper describes the effect of coating 15 cement paste, lime mortar, granite, limestone and brick with two anti-graffiti agents (a 16 water-base fluoroalkylsiloxane, “Protectosil Antigraffiti®”, and a Zr ormosil) on the 17 dispersive comp...

Extending the use of novel anti-graffiti coatings to built heritage could be of particular interest providing the treatments are efficient enough in facilitating graffiti removal and long-lasting to maintain their protective properties without interfering with the durability of the substrates. However, studies of the durability of these coatings are scarce and have been mainly carried out under...

Graffiti, as a social phenomenon, has been with us since people first began painting on cave walls. Our responses to graffiti range from recognition of artistry, to interpreting it as a sign of urban decay and disorder. Major cities respond to tax-payers with this latter response by providing graffiti abatement programs, often at substantial cost; thus, understanding and mitigating the causes o...

Microorganisms that can act as biocleaning agents potentially be isolated from existing graffiti. In this study, a total of 30 different isolates bacteria, fungi and yeasts were obtained black, blue, red silver graffiti coatings exposed outdoors conditions for 10 years. An additional strain was samples black powdered under laboratory 5 Each the most prolific sources (i.e. graffiti) evaluated al...

Graffiti tagging, the inscription of an individual graffiti writer’s unique mark in public space, is considered to be an antisocial behaviour and is a criminal offense. Due to the costs involved in the removal of graffiti tags it would be desirable to deter tagging. A searchable database of graffiti images could be an integral part of the policing system aimed at deterring graffiti vandalism. I...

This thesis will argue that graffiti and street art increase the democratic self-expression values that Christian Welzel’s (2008) democratization theory argues are integral to the process of democratization. In countries where a repressive authoritarian regime allows little room for the population to express themselves, graffiti and street art offer a venue for the voicing of selfexpression val...
