"Turned out there was no plaster lath to plaster over, so sheetrock was used to repair ceiling. MnM also did some plaster crack repairs. Results look excellent. Ready to paint. MnM was extremely punctual, knowledgeable about work required. Started and finished as expected."

Plaster Repair questions, answered by experts

You can plaster over regular drywall, but it's essential to prepare the surface properly. Before plastering, the drywall should be clean, free of dust, and any loose or peeling paint should be removed. Applying a primer specifically designed for plastering can improve adhesion. Some professionals recommend applying a base coat of plaster or joint compound to create a better surface for the plaster to adhere to. Proper preparation ensures a smooth and durable plaster finish over regular drywall.

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.

If you already have plaster walls and ceilings, adding new plaster costs $2 to $10 per square foot. For an average-sized room, that would come out to $1,200 to $10,000. However, the cost to replace plaster with drywall is higher—running between $720 and $1,250 for a 10-by-8-foot wall or ceiling (not including drywall finishing).

To maintain plaster walls, inspect them regularly for cracks and seal them early. Clean the walls by dusting regularly or using a gentle, damp cloth. It's also important to avoid moisture exposure. Repainting as needed will help maintain the wall's appearance and longevity.

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.
