Plaster Repairs

As far as repairing unsightly hairline cracks in stucco or interior plaster, Urethane (water base) caulks work the best - sponged in. Repairing actual voids in plaster, Durabond works best for small to med repairs. If the plaster has lost its bond or broken keys in wood lath, I remove the loose plaster and fill with drywall and veneer plaster. I have never tried to use adhesive or washer screws to fix larger sections of loose plaster. Seems like a lot of work for something that may or may not hold.

I’ve done as you, Brad, where the key bond was broken at the wood lath, unless it was very widespread. Then, I would do as Jeff mentioned above; i.e. cover the walls with 3/8" drywall and jamb extend the trim.
