Pohledové betony a jejich odolnost proti grafiti

Abstract

This diploma thesis focuses on „béton brut“ (raw concrete) and the ways how to improve its properties and resistance to graffiti. This thesis concentrates on verifying effectivity of particular commercial detergents. Theoretical introduction describes general problems of exposed surfaces, including options of concrete surface treatment. Practical part of the thesis verifies effectivity of waterproof coating using laboratory testing, such as moisture absorbing, resistance to water, chemical defrosting agents and resistance of treated surface to water pressure. The thesis continues with testing of variously treated surfaces and their resistance to graffiti. It verifies options of removing the undesirable drawings. The end of the thesis contains economic evaluation of tested detergents.
