Abstract	This paper reports the results of a study conducted to evaluate the performance of ten concrete coatings, representative of five generic types, under varying exposure conditions. The performance of selected coatings was assessed on laboratory specimens by testing their adhesion to concrete, crack-bridging ability, chloride permeability and resistance to moisture and thermal variations. The data indicate that the overall performance of epoxy resin and polyurethane coatings was better than that of other generic types of coatings depending on chemical formulations. Further, a variation in the performance of coatings of similar generic type was noted. The selected coating needs to be tested under conditions similar to the exposure environment. Guidelines for the selection of concrete coatings appropriate for the service conditions are presented along with the performance criteria.Ce papier rapporte les résultats d'une étude qui a été conduite afin d'évaluer la performance d'une dizaine de revêtements en béton représentant cinq types génériques sous des conditions d'exposition variables. La performance des revêtements sélectionnés a été évaluée sur des échantillons de laboratoire en testant leur adhérence au béton, leur aptitude à émousser les fissures, la perméabilité des chlorures et la résistance à l'humidité et aux variations thermiques. Les données indiquent que la performance globale de la résine époxyde et des revêtements de polyuréthanne était meilleure que celle des autres types de revêtements en fonction de leurs formulations chimiques. De plus, une variation de la performance des revêtements de type générique similaire a été notée. Les revêtements sélectionnés doivent être testés sous des conditions similaires à celles de l'environnement d'exposition. Les règles de sélection des revêtements de béton approriés pour les conditions de service sont présentées ainsi que les critères de performance.
