Estimated Time
You just gotta love plaster. That rock-hard substance, which was applied to the walls and ceilings of nearly every house in this country until the 1950s, gives us surfaces that are seamless, mold resistant, fire resistant, and noise deadening.
1. Drill Into the Plaster
Using a 3/16-inch masonry bit, drill a hole in the plaster about 2 inches from the crack. When you hit lath, stop—the bit won't go through wood—pull out the bit, and drill another hole about 3 inches from the first and about 2 inches from the crack. Try to hit a strip of lath with every hole you drill.
2. Prime and seal
Put on safety goggles and disposable gloves, then spray-pump a stream of the acrylic conditioner into each of the holes (but not into any you've marked). One or two squeezes should be enough.
3. Inject the adhesive
Place the adhesive tube's nozzle in one of the primed holes. Gently squeeze the caulking-gun trigger until the creamy glue fills the hole and a little backs out around the nozzle.
4. Clamp the wall
Slip a 2-inch plastic washer over a 1 5/8-inch drywall screw, and drive it into the lath through one of the adhesive-filled holes. The screw pulls the lath against the plaster's back side while the washer gives the screwhead a wide clamping surface.
6. Fill the crack
Mix up a small batch of setting-type joint compound and use it to fill the crack and all the holes. Smooth the wet compound with a trowel; then, as it begins to harden, wet it and smooth it again.
