1. Sketch
A little planning before the job begins can save you a
lot of time and materials later on.
• Sketch out the area you want to cover with gypsum
board. Use the sketch as a guide to determine how
much wallboard you’ll need.
• Remember to plan for the board to be installed
across (perpendicular to) joists and/or studs.
• Try to avoid end joints wherever possible. To do that,
you may want to buy 12
⬘ gypsum board, instead of
8
⬘, depending on your room size.
• If end joints can’t be avoided, stagger them so they
all don’t fall at one end of the room.
Your gypsum board should be stored flat, indoors,
away from moisture and temperature extremes, until
you’re ready to use it. As soon as possible after joint
treatment is thoroughly dry, all surfaces should be
sealed or primed with a vinyl or oil base primer/sealer.
2. Estimate
Once you’ve determined how much wallboard you’ll
need, you can use the charts on the next page to
estimate for nails, joint compound and tape.
If you choose the adhesive/nail-on method for wall
installation (see installation instructions), you’ll also
need some gypsum board adhesive. Use 8 quart-sized
tubes for each 1,000 sq. ft. of wallboard (1 tube to 4,
4
⬘ x 8⬘ sheets; 1 tube to 2
1
⁄2,4⬘ x 12⬘ sheets).
Note: If you’re applying wallboard to masonry walls,
see ‘‘Masonry’’ section for additional materials.
How Much Board Do You Need?
First, figure out the wall and ceiling areas.
Width of the room x Length of the room = Ceiling area
(Width + Length) x 2 x Height of the room = Wall area
For example, a 12
⬘ x 16⬘ x 8⬘ room has a wall/ceiling area
of 640 sq. ft. (Ceiling area: 12 x 16 = 192;
Wall area: (12 + 16) x 2 x 8 = 448; 192 + 448 = 640.)
Look at the Room Measurement Table for a quick
reference. Measure door and windows area and subtract
their square footage from the total square footage to
obtain net room area. Then refer to the Panel Coverage
Table to locate the number of wallboard panels required
for the room. Be sure to allow 10% to 15% overage
for cutting and piecing.

Besides standard 4⬘ widths, ToughRock
™
gypsum board
is also available in a 54
⬙ width that eliminates the need
for gap filler boards in horizontal applications when
walls are 9
⬘ high (see illustration). Using 54⬙ wide
gypsum board when you have 9
⬘ ceilings reduces the
number of seams you’ll need to finish and cuts waste.
