Abstract
When we executed the work in building coating materials on sealants for buldings,there is the case that malfunction such as a soil and the cracking occurs to building coating materials with passing time by the combination. We had executed reseach for compatibility of the building coating materials and the sealants for buildings,in the outdoor exposure test.This outdoor exposure test was the collaborative reseach with Japan Building Coating Materials Association,Japan Sealant Industry Association and Building Reserch Institu. In this study,we examined accelerated test method that can confirm a soil of building coating materials by the influence of sealants for building while comparing the results of outdoor exposure test. By heating at 50°C and using Sakurajima volcanic ash(200mesh) except some combinations, we confirmed the tendency of soil in 7 days acceleration examination, and obtained same result of the outdoor exposure in 14 days acceleration examination.
