Roughcasting is a process of applying a thin layer of mortar to the surface of masonry walls and other building surfaces. The purpose of roughcasting is to improve the appearance and weatherproofing of the surface, and to provide a key for further decoration or rendering.
If you’re looking to roughcast your property, you’ll need to find a roughcasting contractor who can provide the service. Once you’ve found a reputable contractor, they will prepare the surface by cleaning it and repairing any damage.
They will then apply a basecoat of roughcasting mortar, which is usually made from sand, cement, and lime. Once this has dried, they will apply a topcoat, which is usually made from cement and sand. The topcoat is then textured to create the rough finish.
