Fixing Cracks
and Gashes in Drywall
You can repair stress cracks or minor
gashes in drywall easily, using only joint compound and mesh tape. With
most cracks, there is no need to cut out and patch sections of drywall;
you don't have to provide backing if the cut does not go all the way
through the panel. Simply treat it as though it were a drywall joint that
you were finishing from scratch. Apply tape over the damaged area, and
apply the customary three coats of joint compound, sanding the final coat
as necessary
-
Prepare the
crack
Clean out the crack by making a V-shaped cut along its length
with a utility knife or small putty knife. Undercut slightly to create a
key for the patching material to grab on to. Carve out all of the loose
or broken gypsum, and clean off any torn face paper. Push on the panel
around the crack. If the panel shows any movement, drive fasteners along
each side of the crack into the nearest framing members. This will help
to stabilize the panel and prevent further movement
-
Apply the
first coat of joint compound then
apply Joint tape
(mesh tape) directly to the crack, and then spread a first coat (the
rough coat) of joint compound over the tape. Smooth out the joint
compound, feathering its edges. Let this coat dry completely.
-
Apply subsequent
coats and then sand smooth
Using a taping knife as a scraper; knock down any
burrs or high spots on the first coat. Then apply a second coat of joint
compound, and let it dry thoroughly. Scrape down any burrs or high spots
on this coat. Apply a third coat of joint compound, allow it to dry, and
then sand this final coat with sandpaper or a sanding sponge until
smooth.
