We made specimens for tile facing using light-weight adhesive mortars. In a cold region (Kushiro city, Hokkaido), after 10 years outdoor exposure tests, we estimated the durability evaluation. Specimens for external wall didn’t degrade to adhesive strength. Small size specimens degraded to adhesive strength, exposed to rain has caused strength degradation. On the other hand, Light-weight adhesive mortars didn’t catch the frost damage.
