Can I Replace Plaster with Drywall

A: Yes, it’s expensive and messy, but your first thought is your best. To do the job properly you should strip all the plaster from the walls, leave the lath in place and cover it with 3/8 -inch drywall. Tape the joints with fiberglass mesh tape, and cover that with a quick-drying joint compound such as Durabond 90.

Is it worth it to replace plaster with drywall?

Since plaster is considered a higher quality material than drywall anyway, it should not be replaced with drywall in most situations. The one exception is if you’re pulling down the walls to replace the plumbing and electrical systems anyway. In that case, it makes sense to replace with drywall.

Should I remove plaster or drywall over it?

If you just want to cover an unsightly wall where the plaster is in good shape, go ahead and attach drywall over the plaster. If you have long-term plans for the house that include updating wiring and insulation, a good time to do those projects is right after plaster removal when the stud spaces are open.
