B) INSTALLATION TO SMOOTH BACKGROUNDS
1. Framing not to exceed 18” centers.
2. Apply adhesive to back of the panels in 9mm
beads at 16” centers, applying adhesive at
least
3
/4” from edge. Advice from adhesive
manufacturers should be sought prior to
installation of PINnacle panels.
3. Panels must be aligned such that panel edges
fall on framing behind smooth background.
Panels must be fastened to framing behind
smooth background or fixed with screws and
suitable plugs.
4. Apply PINnacle panels to smooth background,
applying hand pressure where adhesive is
located to insure positive contact; screw at
12” centers along edges and 24” centers along
all intermediate framing. Screws or nails should
be of sufficient length to penetrate
3
/4” into
framing behind smooth background. Position
screws or nails
3
/8” from edge of panels.
Finishing screws may be used and left
exposed.
NOTE: If adhesive is omitted, screw or nail panels
6” o.c. along all edges and 12” o.c. along intermediate
framing.
Finishing PINnacle Panels
PINnacle panels may be finished with conventional
paints and stains. PINnacle panels may also be
finished with dye or a wood stain. Consult paint,
dye, or wood stain manufacturer for applications to
wood fiberboard. PINnacle N.C.F.R. must be finished
with a paint, dye, or wood stain that will not affect
the fire rating.
NOTE: It is recommended that a small quantity of
paint, dye, or wood stain be applied to a sample of
PINnacle to assure satisfaction of color and texture
prior to finishing larger panels.
Cutting PINnacle Panels
Cuts can be made easily by either hand or power
sawing. Always use a fine tooth saw whether hand
or power. When cutting the panels, always cut from
finished side. Small cuts (electric boxes, outlets, etc.)
can be made readily with several passes of a sharp
utility knife.
Panel Maintenance
To prevent overall soiling, regular vacuuming or light
brushing to remove dust and grime is recommended.
Lightly sanding the PINnacle panels with fine
sandpaper can be used to remove finger marks
from the surface and for general cleaning.
