Resealing of joints in a typical building structure needs to take place a number of times within the life-time of the building. The resealing process is more difficult than sealing joints for the first time and among the most significant difficulties are the removal of old sealant, and the likely presence of residues left in the joint. This chapter reviews briefly the fundamental concepts of adhesion and uses surface energy measurements to predict the adhesion and durability performance of resealed joints. Tensile adhesion joints were tested before and after UV/condensation (QUV) accelerated weathering, and trends in performance compared favourably with theoretical predictions.
