abstract = "This study examines the influence of various environmental stresses on the behaviour of elastic facade sealants. Five {"}aging methods{"} were used as follows: - aging in constant indoor conditions (reference specimens) - aging under the influence of heat - {"}aging{"} under the cyclic influences of heat and water (two methods) - aging under UV radiation. The influence of aging was studied with maintained extension tests performed at +23 °C, -20 °C and -40 C. Fourteen sealants were studied using concrete sealant concrete test specimens. The results indicate major differences between specimens, in both their cold behaviour and resistance to stress factors. The type of binder, however (silicone, polysulphide, polyurethane or mixtures), did not affect the durability of the product. This appeared to depend on the commercial product or sealant used. The selected test methods appear to be good determinants of product properties. Products which passed the tests without failure could be subjected to further and more severe tests in order to distinguish the excellent from the good.",
