Abstract

Purpose – Paint that is used as exterior finish is subject to the stresses of the climate. The factors of climate such as sun and rain are major source of quick deterioration of paint. The existence of saline air and endogenic salt in substrates in any environment will increase the rate of failure and frequency of repainting of building exterior wall. The purpose of this paper is to ascertain the difference in the frequency of repainting of exterior surface of buildings in areas at close proximity to the Atlantic Ocean and the hinterland. Design/methodology/approach – The research adopted a survey method that involved the administration of structured questionnaire on 384 respondents to elicit data for analysis. SPSS 15.0 software was used to analyse the data. The study area is divided into two zones. Findings – Paint of the same quality from the same manufacturer is found to perform differently. All defects that are caused by salt attack occur earlier in Zone B than Zone A. The frequency of repainting (maintenance) in Zone A is two years due to direct contact with the Atlantic Ocean and Zone B is four years because of the distance from the ocean. Practical implications – This study enlightens the stakeholders in the building industry in the preparation of maintenance schedule for buildings in salty environment. It will also assist the architects in decision making during specifications of exterior finishes in such environments. The maintenance challenges of paint that is applied as exterior finish in salty environment is made clear. Originality/value – It is a novel search into understanding the maintenance frequency of paint that is applied as exterior finish of buildings in areas with direct and indirect contact to salt attack.
