CUTTING & FITTING PANELS
Unlike other panels, PLAS-TEX panels contain no fiberglass or other irritants. They can be scored and snapped similar to drywall
and cut with sheet metal shears. If sawing, use a fine toothed blade. Cut-outs such as for switches should be drilled at the
corners to distribute stress. Test the panel fit by placing it in position without adhesive. Be careful to leave appropriate gap at
panel edges. Do not fit panels too tightly in moldings.
CUTTING & FITTING MOLDINGS
PVC moldings can be cut with razor knife, fine toothed saw or metal shears. Moldings can be applied by coated lath nails and/or
adhesive. If nails only are used, backing material must have adequate holding ability. Do not fit panels too tightly in moldings.
Allow at least 1/8" in all channels for panel expansion after installation is completed. For a watertight installation, a continuous
bead of sealant must be run in all molding channels and mating flanges. Moldings should surround all edges of every panel.
Excess sealant "squeeze out" can be cleaned off while fresh.
APPLYING ADHESIVES OTHER THAN PARKLAND PANEL ADHESIVE
The water-borne family of adhesives, including latex and non-flammable based formulas, will not bond two impervious surfaces to
each other, with the exception of Parkland Panel Adhesive. Because PLAS-TEX panels are impervious to moisture, the wall being
covered must be porous enough to allow for adhesive drying. Wall finishes that are moisture proof must be removed or otherwise
prepared to insure that there is adequate adhesive curing. Always follow adhesive manufacturer's directions completely.
Spread adhesive over the entire back of the panel following manufacturers directions for trowel notch size and working
temperature. Press spreader so that teeth touch panel. Leave only ridges of adhesive on the panel. Be sure to spread the
adhesive on the panel, not the wall.
APPLYING THE PANEL
Position the panel and press against the wall. Take care to insure that
the panels are not fitted too tightly. Use a laminate roller over the entire
surface of the panels to ensure that there is even and complete adhesive
contact with the wall at all points. Remove fresh adhesive and/or caulk.
MECHANICAL FASTENERS
Mechanical fasteners such as nylon drive rivets may be used in addition to adhesive. Install
mechanical fasteners starting from the center of panel. Work systematically outwards,
securing the perimeter last. Arrange fasteners on 16" centers with outer fasteners placed
about 1" from panel edges. At panel seams, fasteners should be staggered to insure a flat
seam. Drill holes in panels for fasteners 1/8" oversize. Do not over tighten.
