PLAS-TEX® NRP® & PolyWall & Silk
WATERPROOF WALL PANELS
panels are waterproof, stain & chemical
resistant. They are USDA compliant and accepted
by the Canadian Food Inspection Agency (CFIA).
PLAS-TEX panels are designed
to install with trowel grade latex adhesive
over structurally sound solid interior walls,
such as drywall or plywood. When installed
with caulked moldings, PLAS-TEX
panels form a moisture resistant, sanitary,
low maintenance wall surface.
The following general instructions
are for installing PLAS-TEX
panels. This guide will help you select
the other materials necessary for a successful
installation. Always follow all adhesive,
sealant and fastener manufacturer's instructions
carefully. If you have installation questions
not answered in this instruction sheet,
please call our toll free number 800-835-4110
between 8:00 a.m. & 5:00 p.m. E.S.T.
on week days.
STORAGE & CONDITIONING
Panels must be stored flat
on a clean, dry surface. Panels should be
pre-conditioned for at least 24 hours at
heat and humidity conditions that represent
temperature and moisture levels for the
area after construction is complete.
ALLOWING FOR MOVEMENT
PLAS-TEX panels expand
and contract with changes in temperature.
Allowing for this movement is very important.
LEAVE A MINIMUM OF 1/8"
BETWEEN AND 1/4" AT THE TOP AND BOTTOM OF
MOLDINGS & CAULKING
Moldings provide a finished
look to an installation. When moldings are
used in conjunction with a quality caulk/sealant,
a waterproof, sanitary, low maintenance
wall can be achieved.
NON-FLAMMABLE or LATEX
PLAS-TEX® panels should be installed using Parkland Panel Adhesive. This adhesive is applied to the wall, rather than the panel, and it has a long open time for ease of installation. Use a 1/8" notched trowel to spread the adhesive. Be sure to cover the entire area. The adhesive will go on milky and turn clear when it is ready to bond. This adhesive may be used with non-porous surfaces, such as DensArmor Plus®, Green Board or painted drywall. Complete installation instructions can be found on the can label or on this website. Click here for complete installation instructions. Adhesive coverage is about 1/3 gallon per 4' x 8' panel.
Other adhesives that may provide satisfactory results are listed below. Generally these adhesives cannot be used over non-porous substrates such as DensArmor Plus®, Green Board or painted drywall. Be sure to follow the manufacturer's instructions. To ensure adequate open time, spread the adhesive on the panel, not the wall. Leave only ridges of adhesive.
SURFACE PREPARATION &
Insure that walls are flat,
clean, dry, and solid. Remove all bumps,
loose plaster or paint and dust. Fill all
low spots and voids. Concrete block walls
may require a leveling coat. Plan where
the panel edges will meet, avoiding placement
directly over drywall or plywood joints.
Decide where to install the first panel
and the best direction to work.
CUTTING & FITTING
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
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
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
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.
