Interior Panels to size with a utility knife and straight edge. Use a power saw only
if equipped with a dust-collection device. Panels may be cut by scoring and snapping or by sawing, working
from the face side.
When using the score-and-snap method, score the panel twice and snap the panel away from the cut face.
The backside of the panels is then broken by snapping the panel in the reverse direction. If a power-operated
saw is used, a low-RPM unit with 3-1/2
Љ carbide blade is recommended.
When necessary, use a rasp or S
URFORM
®
to smooth cut edges. Holes for pipes, fixtures and other small
openings can be cut out with a saw or a drywall router equipped with a special bit (available from Rotozip
Tool Corporation). When a router is used, hold panels away from the wall.
Contractors installing tile and tile-setting materials should always follow current ANSI specifications,
TCA guidelines and the specifications of the surfacing materials manufacturer.

Wall Applications
1. Framing – Space wood and steel framing a maximum of 24
Љ o.c. Framing shall be designed not to exceed L360
deflection for tile and L240 for flexible finishes like paint.
2. Cut panels to size with a utility knife and straight edge. Use a power saw only if equipped with a dust-collection
device.
3. Position all ends and edges of panels over framing members, except when joints are at right angles to framing
members, as in perpendicular applications or when end joints are back-blocked.
4. Install panels vertically whenever possible. End joints should be loosely fit. Install panels a minimum of 3/8
Љ above
the floor. Stagger end joints in successive courses with joints on opposite sides of a partition placed on different
studs.
5. Attach panels to framing supports by spacing fasteners not less than 3/8” from edges and ends of panels
and drive as recommended for specified fastening method. Drive fasteners in field of panels first, working
toward ends and edges.
Framing
Wood
Use corrosion-resistant Type W or Type S buglehead screws or hot-dipped galvanized roofing
nails. Fasteners must be of sufficient length to ensure a minimum 3/4
Љ penetration into wood framing.
Steel
Use corrosion-resistant Type S-12 buglehead screws for 25-12 ga steel framing. When using
25 ga steel framing fasteners should be spaced no grater than 8
Љ o.c. Fasteners must be of sufficient length to
ensure a minimum of 3/8
Љ penetration into steel framing.
