Description
Summary:On-site surface applications of superhydrophobic paint and coating products were investigated for their self-cleaning effectiveness in this study. This paper presents findings from the ensuing visual assessments using a novel method based on digital image processing. Findings confirm the self-cleaning ability of the superhydrophobic surface applications, which has sustained effects over a period of one year. This paper discusses how these findings contribute to the domain of facilities management (FM) to increases the ease of façade maintenance and the maintainability of the superhydrophobic façade coating systems. •Self-cleaning effects of superhydrophobic products were observed over time.•Novel technique using digital image processing used to assess surface dirt staining.•Superhydrophobic surface applications improve ease of façade maintenance.•Knowledge bridge to disseminate maintainability information to practitioners.
