Abstract

Purpose – Painting of buildings predates civilization. The primary purpose was to add beauty or aesthetics to the built environment. It was also to showcase the level of civilization, taste and fashion drive of the people. However, modern findings have proved that paint (when applied as a finishing coat on buildings) can elongate the service life of such buildings due to some characteristic properties it contains and modern additives that are included at production stage. This paper aims to examine some of the properties inherent in paint through which resistance to failure and better performance is enhanced, aesthetics is maintained and maintenance is reduced. It also examines whether these qualities subsist in all environments. Particular attention is given to its resistance to the impact of saline air when used around the Atlantic Ocean. Design/methodology/approach – The research adopted a qualitative and quantitative approach with empirical analysis in examining the performance of paint used in salt laden environment. Findings – It shows that paint used in an environment where saline air and salt is prevalent begins to deteriorate after two years and requires repainting as against the established norm of five to seven years (5-7) in areas that are not exposed to saline air. The impact of saline air is significant at p<0.01. Practical Implication – Maximum life span of current paint products in the area is determined to provide adequate information for the preparation of maintenance schedule for painted exterior. Paint with higher resistance to salt attack is required to enhance the longevity of painted exterior in areas at close proximity to sources of salt. Specifying current available paint for exterior finish will be uneconomical and non-compatible with the principle of sustainability. Originality/value – The authors made a fresh attempt at investigating the life's span of paint used as exterior finish in salt laden area around the Atlantic Ocean due to the peculiarity of the stresses of the tropical region on external finishes. It also compared the result with existing researches. Differences in paint performance are established.
