Installing or repairing plaster on ceilings differs slightly from performing the same motions on a wall. You’ll apply slightly less plaster to lower the overall weight of the ceiling. Wall texturing is common, whereas most ceilings are smooth plaster. Tough coat plaster is strong, meaning you can use less while retaining a solid surface.

Knowing what causes drywall damage can help stop it before it starts. Here are some of the most common causes of drywall damage: 

• Water damage from roof leaks or leaky pipes. 

• Small holes caused by doorknobs, minor accidents, and rodent infestations. 

• Wall dents stemming from moving furniture and minor accidents. 

• Wall cracks that form from a settling foundation or seismic activity. 

• Nail pops from nails and screws in the walls. 

• Large holes that are caused by accidents with heavy objects, children and pets, or sporting equipment.

A 50-pound mirror can be hung on drywall, but only if it has the support of strong hardware. Ideally, you can find the studs behind the drywall and attach the mirror to them; this will give your mirror better stability. Otherwise, confirm that you are using anchors appropriate to the weight of the mirrors. Another technique is to use French cleats—two pieces of wood that fit together, with one piece attached to the wall and the other to the mirror. This allows the weight to be distributed over a wider area.

Popular wall textures include orange peel, knockdown, spray sand, and smooth finishes. Orange peel and knockdown are particularly common choices for drywall as they are simple and cost-effective. Orange peel texture has a lightly bumpy surface resembling the skin of an orange, while knockdown (sometimes called knockout) looks like a stucco finish with flattened high spots. In contrast, popcorn texture has fallen out of fashion, partly due to its past association with asbestos and a shift toward more restrained interior design styles.
