USG SHEETROCK Gypsum Panels - Manual (Page 12)

Tip
On 3/8
Љ, 1/2Љ and 5/8Љ thick
panels, use 1-1/4
Љ Type W
Bugle Head Screws for superior
holding power and high resis-
tance to popping due to wood
shrinkage.
7 Adhesive Attachment
Select the proper adhesive for
specific job requirements. Make
sure that framing is clean,
sound and free from oil, dirt or
contamination. Apply adhesive
and nails per instructions on
adhesive cartridge. Do not use
just adhesive to secure panels.
8 Ceilings
Apply ceilings first. Because
panels are difficult to maneuver
over one’s head, it’s best to
have a helper or two. Fasten
panels to all joists and perimeter
framing. Space nails maximum
7
Љ apart along framing, screws
12
Љ apart, starting in the center
of the panel and working toward
the perimeter. Double-nailing is
recommended to reduce nail
pops.
Tip
Make T-braces consisting of
1x4’s nailed to 2x4 uprights that
are 1/2
Љ longer than floor-to-
ceiling height. Wedge T-braces
between floor and panel to
support panel while driving
fasteners to ensure firm contact
with joists. The preferred
method is to use a panel lifter
tool (available at many building
material rental outlets). See
the table ”Frame Spacing for
Single-Layer Application” on
page 7 for application on
ceilings.
