Construction sealant is the material to maintain the waterproof and airtight functions, and it's function depends on adhesive property, movement capability and weatherability. Testing methods of adhesive property and movement capability are standardized, but the weatherability is not established. Though the construction sealants are influenced by weathering from static to dynamic conditions, many studies of sealant for the weatherability is evaluated on static condition. Factors of sealant weatherability are compounded from degradation on static condition, effect of joint dynamic transformation and climate of region. Our purpose in this study is to demonstrate the quantitative effect of dynamic transformation for the weatherability of sealants by using newly devised testing method.
