"I had old horsehair plaster walls that had holes in them plus a crack plus a cutout where the plumber had to fix a leak. Kyle and his crew did an awesome job of fixing the holes and cutout and crack in the original plaster. They were here on time and left my house cleaner than what they found it. Now itâ s time to paint once the plaster dries. Thanks Wilson Plastering!!"

"We contacted Distinctive Painting because we were having issues painting a ceiling in our house. Turns out the plaster had calcimine and that's why the latex paint wouldn't stick. Mario contacted us back and even though they didn't perform the service, Mario told us exactly what to do and which materials to use to be able to do the job. We were happy to do it (it was only a ceiling...), but his information was crucial. I will also say that I contacted five other painting contractors, left messages, but no other company got back to us. If we ever need a bigger job, we will certainly contact Distinctive Painting!

Plaster Repair FAQs, answered by experts

Yes, you can apply new plaster over an existing plaster surface, such as a wall or ceiling, provided the old plaster is in good condition. Before you begin, check the stability of the existing plaster. The surface must be clean, free of loose material, and have no peeling paint. It is also recommended to roughen the surface slightly to promote adhesion. For older plaster, applying a base coat like a PVA emulsion or a specific bonding agent or primer is crucial. This step makes the existing plaster less porous and ensures the new and old layers adhere properly for a smooth, long-lasting finish.

Technically speaking, you can use drywall primer over plasters. However, oil-based primers work the most effectively on wall plasters. Meanwhile, water-based primers work just as well with drywalls. Nowadays, there are also universal primers suitable for drywall and plaster. Overall, you will be fine as long as you are using a trustworthy brand.

Plaster repair costs range from $4 to $10 per square foot for refinishing, while skim coating can be less expensive, usually between $2 and $5 per square foot. The price you pay for plaster repairs will depend on the extent of the damage, the type of plaster you have on your walls, and the accessibility of the damage. Plaster repair on the exterior of your home tends to be more expensive, as there’s a higher chance that ladders or scaffolding will be necessary to carry out the repair.

Plaster ceilings can sag for several reasons. In some cases, the plaster and other building materials shift and come apart over time, which is why you’ll commonly find drooping plaster ceilings in older homes. Improper installation, foot traffic, and water damage—often from a leaky roof or a broken pipe—can also cause plaster ceilings to sag.

The tool you use to sand plaster will depend on the size of the project. If you’re just working on a small section of your wall to get rid of an uneven spot on the surface, hand-sanding might work. However, for larger projects, a drywall sander can make a huge difference when it comes to both time and elbow grease—and an orbital sander can help for detailed areas such as around ceiling fans.
