Rough-cast is a term used to describe a type of exterior finish used to create a coarse, textured surface. Sometimes, however, you might want to use a different term for this type of finish. Some synonyms you could use include sand finish, stippled, or pebbledash. All of these terms suggest a textured surface created through specific techniques or materials, such as sand or small pebbles mixed into the exterior coating. Additionally, you might use words like rustic, rugged, or unrefined to describe the aesthetic look created by rough-cast finishes. These synonyms convey a sense of natural, rough-hewn charm that can lend character and appeal to many different types of structures.
