How To Repair Outside Corner Cracks In Drywall

If the interior walls of your home are surfaced with drywall, chances are at least ane exterior corner has been crippled past a vacuum cleaner, couch, or runaway Radio Flyer carriage. A coat of spackle and paint won't hide the resulting cracks and disfiguring dents. The only solution is to cutting out the damaged corner and rebuild information technology with a new metal corner bead and fresh articulation chemical compound.

The actual repair takes only a couple of hours, only you will have to await overnight for the articulation compound to dry out before applying the concluding paint coat.

Step i - Uncover One-time Metal Dewdrop

First by using the utility knife to make a vertical slice on each side of the damaged metal corner bead (photo 1). Position each cutting about two inches away from the corner and make both of them long enough to cover whatsoever hairline cracks visible to a higher place or below the point of impact. With the repair area outlined, use the hammer and cold chisel to flake off the old joint compound and betrayal the metal corner bead beneath.

Step 2 - Cut Out Damaged Section

Use the hacksaw to cut through the bead (photo ii); remove a section at least six inches long around the damage. If the bead is screwed in place, remove the screws and pull it out with pliers. If it's nailed, gently pry information technology off without crushing surrounding surfaces. If you lot tin can't pry out the nails without further damaging the wall, use the snips to cut the dewdrop from around the nailheads. Then pull off the damaged section and tap the nails below the surface with the hammer.

Pace three - Measure out and Cut a New Metal Dewdrop Section

Utilize the snips to cut a new piece of bead to fit into the space where the old section was removed. A tight fit is important, so measure carefully to make sure the new piece doesn't overlap the existing one.

To snip through the 50-shaped bead, cut in from each border, and so curve the piece dorsum and forth until it breaks off. Metal corner bead is sold in 8-foot lengths that toll about 2 dollars each.

Step 4 - Attach New Dewdrop Section

You can attach the new bead section with ane v/8-inch drywall screws or ii-inch drywall nails. Nailheads lie flatter and are easier to spackle over, though hammering them in tin crevice the quondam joint compound. Screws hold meliorate, only their thicker heads are a petty harder to muffle, especially if the existing corner bead is covered by a thin coat of joint compound. Our corner was finished with a thick layer, so nosotros attached the new slice with 1 5/8-inch-long drywall screws (photo 3).

Exist sure the new bead'due south edges align with the existing corner. If yous've secured the patch and the edges are misaligned, endeavor tapping them straight with a hammer. If that doesn't work, you'll have to remove the replacement piece and put in a new one.

Footstep 5 - Apply a Thick Glaze of Joint Compound

Once the new department of corner bead is deeply fastened, the adjacent step is to cover it up with articulation compound. Thoroughly stir the material until information technology's shine and lump-free. So utilise the four-inch drywall knife to spread compound over both sides of the corner (photo iv). Don't fuss over this first, thick coat of compound—information technology will shrink, and you'll need to apply at to the lowest degree two more than thinner coats. Just lay it on and wipe it smoothen.

Step half-dozen - Add together More Compound and Paint Over Information technology

Wait for the first glaze to dry (10 to 12 hours). And so, use a sanding block and 80-grit sandpaper to knock down the high spots (photograph v). Switch to the eight-inch drywall pocketknife and spread on a thinner, wider glaze of articulation chemical compound with more care. Apply pressure level on the outer border of the pocketknife as you draw the tool across the surface to form a sparse, "feather border" of compound. Later on the 2d coat dries (about ii hours) lightly sand information technology with 120-dust sandpaper. If needed, apply a thin skim glaze of compound to fill up airholes, scratches, and other flaws. Wait two more hours or then, so wipe down the repair with a damp sponge and utilize 2 coats of paint.
