Plaster Repair FAQs, answered by experts

Drying alone can take 1 to 4 hours to dry to the touch per plaster layer, but some types of plaster take several hours longer to dry. However, this doesn’t mean the job is done because plaster doesn’t fully harden until it cures, which can take a few days to a couple of weeks. It may take even longer if you’re building a new, pretty thick plaster wall. Allow the plaster to cure before painting it.

You can put certain types of plaster over other types, but doing so isn't always the best idea. For example, putting a coat of gypsum over lime plaster is possible, but doing so will limit the lime plaster's breathability and potentially affect its performance.

Since cement plaster tends to leave a textured surface, no matter how much you smooth it, some people prefer to use gypsum plaster as a topcoat over cement plaster, creating a smoother surface.

While it’s most common to sand plaster dry, it is possible to wet-sand plaster, too. Doing so can reduce the amount of plaster dust released into the air and make it easier to work in smaller, more delicate areas (such as around wall trim). However, some people find that wet sanding leads to more imperfections, which is why larger walls are more often dry sanded to ensure an even finish.

Look for flaking paint or air bubbles that burst and then flake away. Paint will begin to flake after being exposed to minimal moisture or water, so it’s a good indicator of any water damage. If you notice your paint starting to flake, feel the plaster underneath to see if it is soft or damp.

While you should consult with a ceiling professional for larger cracks, especially if you’re not sure what’s causing your ceiling to crack, you can certainly try to repair small cracks on your own. If you’re up for the task, here’s how to repair ceiling cracks for $150 or less.
