My ceiling is sheetrock or something similar covered with a thick layer of spackling like material that has a wavy design in it. What is this procedure called? (The design isn’t elaborate, it’s just waves and shapes.)
I need to find some materials to repair some damage to this part of my ceiling, but I’m not even sure what to ask for or what the procedure of making the design is called and I don’t want to pantomime.
I’m assuming there are little tools just for this.
