How many layers of stucco should they be applying?
If their applying a natural stucco to the surface, most cases would require a three coat application. One base coat, one scratch coat and a finish coat. In an acrylic finish, we apply one ½” coat of base and wait ten days to dry. This drying time allows for any movement that may occur in the stucco. We then apply a 1/8″ coat of finish. Acrylic finish allows for slight movement because it can move with the temperature changes that occur. The temperature changes cause mortar to restrict and expand. This is why many natural stucco’s crack. Natural stucco does not naturally move with the temperature changes.
