Acrylic surface treatment applied to architectural High-Performance Concrete (HPC): Identification of potential pitfalls on the way to long-lasting protection
Source abstract
Abstract
Surface treatment is recommended for the protection of High-Performance Concrete (HPC) against weathering. This laboratory study highlighted the underlying weathering mechanisms of treated HPC surfaces when cyclically exposed to UV irradiation and condensation. The extent of the weathering-induced changes in colour of the acrylic films (perceived as opacity of former transparent films) were revealed to depend on the application amount (associated with film toughness) and the application method (associated with film quality). To ensure long-lasting protection through surface treatment, the films have to be free of pinholes and sufficiently thick in order to withstand stresses resulting from weathering.
