Wallflowers
®
within 12 hours after sanding/grinding to
prevent re-oxidation. Metal substrates
are non-porous – follow all installation
instructions, trowel sizes and flash times
for non-porous substrates.
4. FACTORY CORNER INSTALLATION
Flexco Factory Corners, Rubber Corner
Blocks and Mini-Rubber Corners must
be installed prior to Wallflowers® Wall
Base materials. Ensure substrate is
suitably prepared prior to installation,
as manufacturer is not responsible for
substrates that have not been properly
prepared. Ensure adhesive is approved
for use with wall base material and that
proper trowel or applicator type and size is
used, as manufacturer is not responsible
for any and all adhesion issues related to
improper adhesive selection or usage.
Corners and corner blocks must be
installed on 90° corners - do not attempt
to install corner blocks over other angles,
including 135° angles. Install adhesive to
the back of the corner or corner block and
install onto corner. Mechanically fasten
the returns / wings of corner blocks with
staples or brad nails to increase stability.
When fastening, ensure that staples or
nail heads do not protrude from return,
as they may telegraph through wall base
material.
5. WALL BASE INSTALLATION
Prior to installation, ensure wall base
material has been properly acclimated and
that ambient conditions are within normal
operational ranges. Ensure substrate is
suitably prepared prior to installation,
as manufacturer is not responsible for
substrates that have not been properly
prepared. Ensure adhesive is approved
for use with wall base material and that
proper trowel or applicator type and size is
used, as manufacturer is not responsible
for any and all adhesion issues related to
improper adhesive selection or usage.
When installing wall base in areas that
may be subjected to abuse, such as
intentional removal, the Excelsior AW-
510 or C-630 adhesives must be used to
prevent removal.
Cut wall base to desired length and fit
tightly against corner blocks or allow for
job-site formed corners detailed in section
6.
Apply adhesive to the back of the wall
base per adhesive instructions, ensuring
that wet-set adhesives do not come
within 1/4" of the top of the wall base.
Install wall base to substrate, ensuring
that wall base material is not stretched
or over-compressed during installation.
Stretching material or over-compressing
seams and corners may cause wall
base to shrink and/or curl/delaminate,
respectively.
Periodically lift material to ensure proper
adhesive transfer - adhesive should cover
90% of material. Using a suitable hand
roller, carefully roll material in the direction
of the last piece installed with a hand
roller within 30 minutes of installation.
Wallflowers® wall base and corner blocks
installations can be enhanced by using
Flexco’s matching Colored Caulk to fill any
voids or imperfections. Allow wall base
to cure for the required period of time -
do not disturb wall base installation until
curing time is complete.
JOB-SITE FORMED CORNERS
Ensure substrate is suitably prepared
prior to installation, as manufacturer is not
responsible for substrates that have not
been properly prepared. Ensure adhesive
is approved for use with wall base material
and that proper trowel or applicator type
and size is used, as manufacturer is not
responsible for any and all adhesion issues
related to improper adhesive selection or
usage.
OUTSIDE CORNERS
To create an outside corner on-site using
wall base material, position wall base
areas and in or around commercial
kitchens. Do not install in areas that may
be subjected to sharp, pointed objects.
Do not allow product to be directly
exposed to extreme heat sources, such
as radiators, ovens or other high-heat
equipment. May be susceptible to staining
from harsh disinfectants, cleaning agents,
dyes or other harsh chemicals – ensure all
chemicals and materials that may come in
contact with wall base will not stain, mar
or otherwise damage the material prior to
use.
3. SUBSTRATE PREPARATION
All substrates must be clean, smooth,
permanently dry, flat, and structurally
sound. Substrates must be free of visible
water or condensation, dust, sealers,
water-based / acrylic paint, residual
adhesives and adhesive removers,
solvents, wax, oil, grease, asphalt,
gypsum compounds, visible alkaline salts
or excessive efflorescence, mold, mildew
and any other extraneous coating, film,
material or foreign matter. Substrate
must be a structurally sound interior wall
surface, such as dry plaster, cured drywall,
fiber-reinforced plastic (FRP) panels,
fiberglass, exterior grade plywood (Group
1, CC type), concrete, metal and masonry.
Any cracks, voids, divots, grout lines and
imperfections must be filled with a patch
or filler suitable for the substrate.
When installing directly over a resinous
products, such as an epoxy paint, ensure
that coating is dry to the touch and has
cured for the prescribed length of time.
Substrate must be clean, dry, sound
and free of contaminates. Material to be
installed over non-porous substrates, such
as epoxy paint, FRP panels or fiberglass,
must be installed with the Excelsior C-630
Contact Adhesive.
Metal substrates must be thoroughly
sanded/ground and cleaned of any
residue, oil, rust and/or oxidation.
Substrate must be smooth, flat and
sound prior to installation. When installing
in areas that may be subject to topical
water or moisture and/or high humidity,
an anti-corrosive coating must be applied
to protect metal substrate. Contact a
local paint or coating supplier for coating
recommendations. Install wall base
