The short answer is yes, a sagging plaster ceiling is dangerous. Sagging plaster on a wall is something you should fix immediately, but it isn’t a major concern. If the same type of sagging occurs on a ceiling, however, you could be in danger of your ceiling falling in large chunks. When plaster sags, it loses its strength and ability to hold itself up. The bonds that hold it together are strong, though, so if a sagging area falls, it will take large pieces down with it.

You can plaster over an old plaster ceiling if the existing plaster is in good condition. Ensure the surface is clean, free of loose material, and roughened slightly to promote adhesion. Applying a bonding agent or primer can further enhance adhesion. Proper preparation ensures a smooth and long-lasting plaster finish.

Whether you can repair or install plaster yourself depends on the project size and your tolerance for DIY projects. You may feel perfectly comfortable taking on a small plaster repair project, but prefer to leave a room restoration or renovation to a local plaster repair professional.

Since the project's end result, including its durability and appearance, depend on how well you prepare the wall and apply the plaster, you may want to let a professional take it on if you're not 100% confident.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly.
