The two most common drywall thicknesses for ceilings are 1/2-inch and 5/8-inch. For most standard residential applications, 1/2-inch drywall is sufficient and widely used. It provides adequate support and is lighter and easier to handle during installation compared to thicker sheets. However, 5/8-inch drywall is often used for specific cases where additional benefits are needed. It is heavier but provides superior sound dampening and fire resistance. You should consider using 5/8-inch drywall for ceilings in commercial buildings, between a garage and a living space, or above a finished basement to meet building codes or for enhanced soundproofing.

Drywall tape is made of paper, while drywall mesh is made of fiberglass or metal. Drywall mesh patches are suitable for repairing small holes in drywall, while paper drywall tape holds a crease better for corners. You need joint compound to adhere drywall tape to the wall, while mesh patches may be self-adhesive.

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.

There are a few ways to figure out if your walls are plaster or drywall, but the pushpin method is probably the easiest option. To try it, choose a part of your wall where you can insert a pushpin or thumbtack without leaving an obvious mark. If it goes in easily, you have drywall. But if the wall is tough to penetrate, that’s plaster.
