Are there special considerations when setting Cast Stone in Hot or Cold Weather?
Both hot and cold weather present their own set of challenges while setting Cast Stone. In hot weather care should be taken to soak the Cast Stone prior to setting and to be sure the mortar has and retains sufficient water to ensure a proper bond to the Cast Stone. The increased rate of hydration of the cement and favorable curing conditions in hot, humid weather will help develop masonry strength provided sufficient water is present at the time of construction and for a curing period of three days. In cold weather care should be take to follow the recommendations set forth by the International Masonry Industry All Weather Council. Further information can be found in the Cast Stone Institute Technical Bulletins # 41 (Cold Weather Setting Practices) and # 48 (Hot Weather Setting Practices).
