USG SHEETROCK Gypsum Panels - Manual (Page 11)

Tips
For 1/4
Љ, 3/8Љ and 1/2Љ thick
panels, use 1-1/4
Љ wallboard
nails. For 5/8
Љ panels, use
1-3/8
Љ wallboard nails.
Drive nails in straight, not at an
angle. Do not overdrive or
countersink nails. This results
in breaking the face paper or
fracturing the gypsum core. If a
nail happens to go in crooked,
hold the panel tight against the
framing and drive a second nail
in about 2
Љ from the nail that
punctured the paper. Then drive
the first nail in below the surface
of the board.
Double-nailing reduces the like-
lihood of nail pops. It is highly
recommended for ceilings. Drive
first nails 12
Љ o.c. along framing
in the field of the board and sec-
ond nails about 2
Љ from the first.
Fasten the perimeter 7
Љ o.c. for
ceilings and 8
Љ o.c. for walls.
6 Screw Attachment
Space screws maximum of 12
Љ
apart on ceilings, 16
Љ on walls
and at least 3/8
Љ from ends and
edges of panels. Sink screws to
just below the panel surface,
leaving the paper intact.
Use an electric screwgun equip-
ped with an adjustable screw
depth control head and Phillips
bit. If an electric drill is used, be
careful not to overdrive screws.
