How to repair a plaster ceiling: restore its smooth surface

Wondering how to repair a plaster ceiling? There are a few different ways you can do it. Which method you use ultimately comes down to the cause of the damage and how extensive it is (and sometimes the structure of your ceiling, but more on that later), so it’s always best to start with a little investigation. 

The good news is that in most cases, it’s relatively simple to restore the surface to its smooth former glory, meaning that you won’t have to plaster a ceiling in its entirety.
