Tools
The materials and tools you’ll need for most repairs are:
1. All-purpose joint compound
2. Drywall tape
3. Gypsum board scraps
4. Gypsum board nails
5. Utility knife
6. 59 (127 mm) and 109 (254 mm) taping knives
7. Hammer
8. Safety glasses
Medium to Small Holes
1. Cut out a rectangle around
damaged area with knife or
keyhole saw.
2. Cut a scrap section of gypsum
board, with top and bottom
slightly larger than the hole.
3. Place a piece of string through the center of scrap.
4. Apply all-purpose joint compound to edges of
scrap, then slide into hole.
5. Center scrap and pull tight until joint compound
is set.
6. Cut string, fill hole with joint compound.
7. Additional finish coats may be necessary.
Dents and Gouges
1. Fill with all-purpose joint compound or sandable
setting compound.
2. Touch up with paint.
Large Holes
1. To patch larger holes,
you may have to cut the
gypsum board back to
the studs to replace the
entire damaged section.
2. Apply gypsum board
tape and finish off with all-purpose joint compound.
Nail Pops
1. Drive new nail about 19-29
(25.4-51 mm) above and below
the one that has popped.
2. Push panel close to the stud while
you “dimple” the two nails. (See
Installation section for explanation
of “dimpling.”)
3. Remove loose material from
dimpled areas, sand lightly.
4. Fill dimpled area with all-purpose joint compound,
let dry overnight.
5. If shrinkage occurs in drying, re-apply all-purpose
joint compound. When patch is dry, sand lightly.
6. Prime and texture or paint to match existing wall.
Cracks
For large cracks, use all-purpose joint compound and
drywall tape.
1. Sand the area about 69 (152 mm) on each side of
the crack.
2. Work all-purpose joint compound down into crack.
3. Center tape over the crack and press down firmly
with a 59 (127 mm) drywall knife.
4. Cover tape with a coat of all-purpose joint
compound. Smooth it out well beyond tape edges
by feathering.
5. Allow patch to dry overnight. Apply another coat
of all-purpose joint compound which extends 1 1 ⁄
2 9
(38 mm) wider than the last coat. Smooth edges,
let patch dry. Sand lightly.
• Narrow cracks may be filled with all-purpose joint
compound alone. Use a stiff brush or screwdriver
to remove loose material from the crack.
• Dampen edges of the crack with water.
• Fill deep cracks almost to the surface. Let dry, then
add a thin coat of all-purpose joint compound.
Smooth out 29 (51 mm) on each side of crack, by
feathering. Let dry. Sand smooth.
