Outside and Inside
Corners
Measure wall height to be
covered by bead. Using
metal snips, cut bead
1/2 in. shorter than the
wall height. Cut first from
one side and then the
other; bend and snap.
Using a 4 in. knife, apply
an all purpose or taping
compound to wallboard
surfaces, extending
compound just wider
than the trim.
Press paper faced metal
bead in place and embed
by running a knife over
each side with even
pressure at a 45° angle.
Once bead is in place,
use a 4 in. knife to apply
a thin layer of compound
over the paper facing,
while pressing out
excess compound and
eliminating air bubbles.
A damp sponge may
be used to remove
excess compound
beyond the blade edge.
Allow to dry.
Using a 6 in. knife for
outside corners (4 in.
for inside corners),
apply another coat of
all purpose or topping
compound. Keep this
coat as smooth as
possible, feathering
out approximately 1 in.
beyond previous coat.
Let dry.
