You’ll want to inspect your plaster walls for signs of damage before painting. If you notice soft spots, deep cracks, bubbling, or areas where the plaster is crumbling or pulling away from the wall, it likely needs repair. While small hairline cracks are common and likely cosmetic, you should address larger issues before painting to ensure a quality, smooth finish.

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.

Smaller is better when patching holes with spackle. Any holes wider than four to six inches in diameter tend to be too wide to repair with spackle alone. You'll likely want to patch bigger holes with a drywall panel. 

Even holes measuring up to 6 inches may be challenging to fill with spackle alone. For best results, purchase a wall repair patch made from wire mesh. Cut the patch to fit over the hole, then use the spackle to hold it in place. Apply the spackle over the patch as you would for a smaller hole.

Skimming is covering drywall with a layer of drywall compound after installation or to smooth old walls. Plastering is covering walls with a mixture of gypsum or lime, cement or sand, and water. Plastering is more costly and labor-intensive than skim coating. Some homeowners and professionals refer to skim coating as plastering, even though the material spread over the wall is totally different.
