Repair Damaged Plaster

Q: I have an old house that has lath and plaster walls. When taking off some wallpaper, a lot of plaster came off. Can I repair this with a drywall product?

A: If the remaining plaster on the lath is fairly solid, you can repair the damaged area with new plaster. Pick up some Plaster of Paris at a hardware store and mix it up according to the package instructions. Trowel the plaster into the damaged area. Do this in a couple of applications so the weight of the plaster doesn’t pull it off the wall before it dries. Once the repair has completely dried, you’ll need to sand and apply an oil-based primer, assuming you plan to paint the wall.
