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.

What to use to clean plaster?

Vacuum cleaner (optional) Broom and dust pan (optional) Tip. Use a vacuum or broom to sweep up any dust or plaster particles between each step. If you don't have matching paint, pry out a chip and take it to your local paint store or home improvement store to be matched. Warning.

Can Durabond be used on painted walls?

Do not use Durabond on painted surfaces; it won't adhere properly. Maintaining a busy household amid the chaos of daily life can be challenging. Even the most careful family occasionally cuts a corner too close or bumps into a wall, resulting in chips and dings in the plaster.
