Significance and Use | ||||
5.1Graffiti on buildings and structures is a significant problem in various regions across the country. A variety of coatings have been developed to be either resistant to the application of paints/marker or to aid in their removal. This standard practice describes a procedure for evaluating the effectiveness of anti-graffiti coatings applied to various concrete, masonry and natural stone substrates. It does not address graffiti removal on metal or any other non-mineral substrate. 5.2This practice only addresses graffiti removal on substrates in a laboratory environment, that have not been exposed to either natural or artificial weathering. Specification D6578 describes a method for graffiti removal after both natural and artificial weathering. |

1. Scope | ||||
1.1This practice covers a basic method for evaluating the performance of anti-graffiti products on mineral building substrates by a series of increasingly abrasive cleaning methods. The anti-graffiti materials are applied to a series of concrete, masonry and natural stone specimens for evaluation. Graffiti resistance is based on how a defined set of markings are removed by a designated set of cleaning techniques. 1.2This practice also defines a procedure to evaluate graffiti removal after re-marking with subsequent re-cleaning. It does not address the re-treatment of substrates after a material is no longer graffiti resistant. 1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
