Steps to Repairing Plaster Walls
- Protect walls and floors in the repair area with plastic drop cloths; use painter’s tape to hold the drop cloths in place.
- Use a 3/16-inch carbide-tipped masonry drill bit to bore holes through the plaster, but not through the wooden lath. Drill evenly spaced holes—about every 3 inches—around damaged wall area.
- Clean dust from the holes with a wet/dry vacuum.
- Spray liquid conditioner into each hole; remove any conditioner that runs down the wall with a sponge.
- Trim the adhesive tube’s nozzle with a utility knife. Then, inject adhesive into each hole by giving the caulking gun’s trigger one full squeeze.
- Immediately after squeezing adhesive into the holes, use a drill/driver to screw a plaster ring into as many holes as necessary to pull the plaster tight against the lath.
- Allow the adhesive to dry, then use the drill to remove all the screws and plastic rings. If necessary, scrape the rings from the wall with a putty knife.
- Scrape off any high points of adhesive with the 6-in. putty knife
- Apply a thin coat of joint compound to the wall using the putty knife.
- Let the compound dry overnight, sand the surface lightly with 120-grit sandpaper, then apply a second, thinner compound coat.
- Prime and paint the wall.
