How To Repair Gouged Drywall

You lot merely gotta love plaster. That stone-hard substance, which was practical to the walls and ceilings of most every house in this country until the 1950s, gives the states surfaces that are seamless, mold resistant, burn resistant, and racket irksome. But what to do when plaster cracks, buckles, and pops loose? It's a perplexing question for many of our readers, including Tim Thorp, whose firm in Providence, Rhode Island, is filled with badly blemished plaster.

"How practise I patch 100 years of gouges, cracks, and screw holes so the walls look flat and make clean when painted?" he asks u.s. in an email. Here, Tom Silva shows how to repair plaster walls to make them wait equally good as new.

The central to any gear up is to reunite the plaster with the strips of wood board underneath. Otherwise the cracks come back, no affair how many times you patch over them. That'south why This Old House general contractor Tom Silva usually reattaches lath with screws and metallic washers before attempting a repair.

Recently, though, he tried Large Wally's Plaster Magic, a homeowner-friendly agglutinative that uses glue instead of screws. While it costs more than the spiral-and-washer method—a vi-tube kit runs $120, versus $20 for 120 metallic washers—the last finishing is easier and looks better considering there aren't any washers to cover. Plus, a glued bond lasts longer than a screwed connectedness.

1. Drill Into the Plaster

• Using a 3/16-inch masonry bit, drill a hole in the plaster about ii inches from the crevice. When you hit board, end—the bit won't go through forest—pull out the fleck, and drill another hole about iii inches from the first and about 2 inches from the crack. Try to hitting a strip of lath with every pigsty you lot drill. If you lot miss, the fleck will sink in right to the chuck.
• Mark such holes with a pencil as a reminder not to inject them with primer or adhesive in the next steps; endeavour drilling once more nigh half an inch up or down.
• Continue until in that location is a series of holes about 4 inches apart on both sides of the crack. Vacuum the plaster crumbs out of all the holes.

2. Prime and seal

• Put on safety goggles and disposable gloves, so spray-pump a stream of the acrylic conditioner into each of the holes (just not into whatsoever yous've marked). One or two squeezes should exist enough.
• Spray the edges of the scissure, as well, and clean upwards drips with a wet sponge. Wait 10 minutes for the milk-thin conditioner to soak into the plaster and wood.

3. Inject the adhesive

• Slip a 2-inch plastic washer over a 1 v/eight-inch drywall screw, and bulldoze it into the board through one of the adhesive-filled holes. The spiral pulls the board confronting the plaster'due south back side while the washer gives the screwhead a wide clamping surface.
• Establish washers about viii to 12 inches apart on both sides of the crack.

5. Wipe and wait

• Wipe away whatever excess adhesive with a moisture sponge.
• Wait a 24-hour interval or two for information technology to cure, and then back out the screws and scrape off the washers. (Relieve them for some other plaster-repair project.) Besides, scrape off whatsoever dried adhesive poking out of the holes.

half-dozen. Fill the crack

• Mix upwardly a small batch of setting-type articulation compound and use it to fill the crevice and all the holes. Smooth the wet compound with a trowel; then, equally it begins to harden, wet it and shine it again.
• Later on the chemical compound sets, sand the area lightly, then prime and pigment.
