4. STAIR NOSING & LANDING
TRIM INSTALLATION
Prior to installation, confirm stair nosing
placement and the placement of adjoining
materials per design specifications.
Inspect all stair nosings prior to installation
to verify that there are no visible defects,
damages or excessive shading variations.
Some products, colors and textures have
latent and acceptable color and shade
variations. If there are concerns regarding
shade or color variation, do not install
material and consult sales representative
and manufacturer’s technical staff. Prior
to trimming stair nosings, any specified
Flexco Stringer or equivalent must be
installed (the inclusion of Flexco Stringers
is optional). Stair nosings which have
an undercut, underlap or flange must
be installed prior to the installation of
any adjoining flooring material or riser
material. Fit stair nosing to step and
mark material for trimming. Carefully trim
material along marked line using a razor
utility knife or a miter saw with a 60 tooth
or greater carbide tip blade. Confirm that
stair nosing fits tightly on step, ensuring
material is not over-compressed. Prior to
installation, clean the underside of the
stair nosing with a clean rag or towel and
denatured alcohol or equivalent solvent
adhesive remover. In areas which may be
exposed to excessive moisture or heavy
foot traffic, lightly sand the back of the
stair nosing to improve adhesion.
Apply a 1/4" - 1/2" bead of the EN-610
to the interior nose of the stair nosing.
All stair nosings must have the EN-610
installed in the stair nose. Failure to do
so may result in premature wear and
damage which could compromise egress
safety. Apply EN-610 to both surfaces of
the stair nosing and spread using a 1/8"
saw-tooth spreader. Be sure to achieve
75% adhesive coverage on both surfaces
of the nosing. Install nosing onto step
and roll material with a hand roller or
equivalent. Visually inspect installation to
ensure that material has not shifted and
that adhesive has not been squeezed out
of joints or compressed onto surface.
Avoid walking, kneeling or working on
material until adhesive has cured for light
foot traffic. Working on material that is
installed into wet adhesive could cause
adhesive to displace. When working
off of material is not possible, use a
kneeling board or equivalent to disperse
weight evenly and prevent adhesive
displacement.
To prevent movement, dust, dirt, debris
and topical moisture in or around seams,
tape seams together after installation
using a multi-purpose masking tape
intended for flooring and hard surfaces.
Pay close attention to open times to
avoid adhesion issues. This may require
installing material in smaller sections.
5. VERTICAL ACCESSORY
INSTALLATION
Prior to installation, ensure accessory
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 accessory material and that
proper applicator type and size is used,
as manufacturer is not responsible for
any and all adhesion issues related to
improper adhesive selection or usage.
Accessories which have an undercut,
underlap or flange must be installed prior
to the installation of any adjoining flooring
material or wall base. When necessary,
carefully trim material using a razor utility
knife or a miter saw with a 60 tooth or
greater carbide tip blade. When installing
with a radius, ensure material can be
formed to accommodate radius prior to
installation and use the C-630 Contact
Adhesive to ensure that accessory will
stay in place. Some accessories may be
heated to achieve some radius'. If heating
an accessory to form a radius, confirm
material can accommodate radius prior to
permanently installing.
Apply adhesive to the back of the
accessory per adhesive instructions and
install accessory to substrate, ensuring
that accessory 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,
all chemicals and materials that may
come in contact with the accessories 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. Vertical
substrates 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 cementitious patch (such
as the Excelsior CP-300) 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
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.
