"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."

"Mike is very friendly and courteous, as well as quite dedicated to doing a good job. When installing our new attic stairs and door, he spent numerous hours over two days. I saw him place the weatherstripping perfectly, and both this and the paint look excellent. As he works, he explains the steps of what he is doing. After finishing, he called later on to make sure that there were no problems. He is easy to contact and returns calls. I would therefore highly recommend Mike and Palma Construction."

Plaster Repair questions, 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.

Your walls are likely cracking due to fluctuations in the temperature outside. Drywall tends to expand and contract when temperatures and humidity levels change, and this repeated movement can lead to cracks in your walls, particularly around door frames. If you have multiple diagonal cracks, you may want to have your foundation inspected, as cracks can also be a sign of a bigger issue.

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.

It’s not a good idea to plaster over broken plaster (unless by broken you’re referring to cracked, in which case that’s perfectly fine). However, broken plaster can be a sign of a larger underlying issue like foundation damage or severe damage to the lath holding up the plaster, so it’s worth investigating before you simply plaster on top of the damage.

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.
