1, decorative mortar

Decorative mortar refers to a mortar that is applied to the surface of the base material to protect the base layer and increase the appearance. Plastering mortar is used for the wiping of brick walls. Due to the strong water absorption of the bricks and the large contact area between the mortar and the base layer and the air, moisture is lost quickly, and lime mortar should be used. When there is waterproof and moisture proof requirements, apply cement mortar.
