Service life prediction of paint coating of Algiers building envelopes by applying a multiple linear regression analysis
Keywords:Paint coating; Degradation; Service life prediction.
The durability of a building is strongly related to the service life of its various components, including the coatings of its envelope. The paint on the building envelope is the first protective layer exposed to the harmful effects of the climate and environmental conditions. These effects are manifested over time by degradations such as color change, cracking, peeling, etc. In this contribution, a predictive model of the service life of paints coating, applied on cementitious materials of building envelopes located in Algiers, is proposed. The model is based on a multiple linear regression analysis of descriptive results of visual investigations combined with in situ tests on the degradation of the facade paints of 45 buildings sample, selected according to their age, their distance to the coast as well as their orientation with respect to the climatic factor exposures. The proposed predictive model satisfactorily reproduces the field results.
