USG SHEETROCK Gypsum Panels - Manual (Page 17)

Keep the blade clean, especially
of dried bits of compound, to
avoid leaving scratches in the
wet joint compound as you draw
the knife over it. Discard any
compound containing dried bits
of material. Clean blade by
drawing it over edge of pan.
While embedding tape, draw the
knife slowly along the length of
the tape to provide an even
distribution of joint compound.
Don’t worry about a few grooves
or streaks in the joint com-
pound. They will be covered
over in the subsequent coats.
12 First Coat, Inside Corners
Use a 5
Љ joint finishing knife
to apply thin layer of joint
compound on both sides of
corner. Extend compound
slightly beyond area to be
covered by tape.
Fold tape along center crease
and lightly press into position
with your fingers.
Tightly embed tape as with
other joints.
