Tips
To join panels at an inside cor-
ner, butt the second panel
against the first and fasten the
end of the second to a stud.

To join panels at an outside cor-
ner, lap the end of the second
board over the end of the first,
and fasten both panel ends to
their common stud.

9 Drywall Inspection and

Preparation
After drywall installation, inspect
the surface you are going to fin-
ish. Drywall panels must be firmly
attached to the framing, properly
lined up, butted together, and not
damaged. Remove any drywall
dust or other particles from the
wall. Tape and joint compound will
not adhere well to dusty surfaces.
This can result in joint cracking,
and may cause the tape to sepa-
rate from the joint.

Make sure that your fasteners are
properly seated by drawing a
clean knife over each fastener. If
you hear a metallic ring, drive the
fastener below the surface. Be
careful not to break the face
paper.

Remove any loose paper, and cut
out any soft spots or bulges in the
board.

Butt joints, where cut board edges
meet, should be cut with a “V”
groove to remove fuzzed paper.

Deep holes and gaps larger than
1/8

Љ should be prefilled with joint

compound before finishing.

10 Corner Bead and Metal Trim

HEETROCK

RAND

Paper Faced Metal

Bead and Trim

Apply compound to both sides of
corner, extending 2

Љ on each

side. Cut bead to desired length.
Align tightly, pressing firmly to set
bead. Be careful not to bend. Use
taping knife to embed bead firmly
into the joint compound by run-
ning the knife at a 45° angle over
the corner with even pressure.
Remove excess compound using
the knife to eliminate any air bub-
bles under the paper. Allow to dry.
Keep the nose of the bead clean
with a slightly damp sponge.

Tips
When bullnose bead is to be
applied to an outside corner, the
drywall panels forming the corner
should not be overlapped. This
will permit the rounded bead to fit
snugly around the corner. (For
inside corners, no special align-
ment of panels is necessary to
accommodate bullnose bead.)

If regular right-angle bead is to be
used for an outside corner, the
boards should overlap as usual.

Application of paper-faced metal
bead will be quicker and easier if
you apply compound to the bead
using a hopper. This is a simple
piece of equipment that spreads
compound on the bead as you
pull it through the hopper’s spe-
cially designed openings or
gates. For best results, you
should place the hopper on a
plastic pail to collect any excess
compound. Cut “V” shapes out of
the pail on both sides so that the
bead can enter and exit smoothly
as you push it through the hop-
per.

The hopper has two differently
shaped gates. One is for right-
angle bead, and one is for bull-
nose bead.
