RUBBER STAIR TREADS,

RISERS & STRINGERS

raised design

material with divider, mark the riser with

the divider to determine scribe line. Use

a suitable knife to trim riser along the

scribe mark.

Once the right side of the riser is scribed

and trimmed, reposition the riser to

align to the left side of the step. Reset

the divider to the distance between

the center mark on the step riser and

the center mark on the stair tread. Use

divider to scribe riser as before and trim

riser along scribe mark, creating a slight

undercut. Ensure that riser ﬁts the step

snugly against stringers and stair tread

below without over-compressing riser

material. Avoid over-compressing toe to

avoid premature wear and damage.

The seam between the leading edge of

the stair tread and the stair riser should

be treated using one of the following

methods.

SCRIBED SEAM METHOD

When butting stair tread and riser seams

using the Scribed Seam Method, ensure

that the stair tread above and below the

riser, as well as the riser itself, have been

trimmed and ﬁt the step snuggly. Ensure

the stair tread below the riser is in place

prior to scribing the riser to ensure a

tight ﬁt to the leading edge of the stair

tread above.

Overlap the stair tread above the riser

with the riser while ensuring that riser

toe is not over-compressed. Using the

leading edge of the stair tread as a

guide, use a divider or a marking tool to

scribe the riser. Use a suitable knife to

trim riser along the scribe mark.

OVERLAPPING SEAM METHOD

When overlapping stair tread and riser

seams, ensure that the stair tread and

riser have been trimmed and ﬁt the

step snuggly. Risers do not normally

require trimming on the top edge prior

to installation when overlapping seams.

However, if the top edge of the riser

extends up to or over the height of the

step, trim riser to 1/4" - 1/2" from the top

of the step to allow space for the EN-610

Epoxy Nose Filler Adhesive.

INSTALLATION

Ensure step substrate is suitably prepared

prior to installation, as manufacturer is

not responsible for substrates that have

not been properly prepared and tested

for moisture. When using the Excelsior

TP-620 Pressure Sensitive Tape Adhesive

or the C-630 Contact Adhesive, be sure

to a clean dusty and/or cementitious

substrates with a damp mop or sponge

prior to installation to remove dust, dirt

and debris.

Ensure adhesive is approved for use

with stair tread material and that

proper trowel type and size is used,

as manufacturer is not responsible for

any and all adhesion issues related to

improper adhesive selection or usage.

Prior to installing adhesive, ensure all

stair treads and risers have been trimmed

and all stringer materials have been

installed. Clean the underside of the

stair tread with a clean rag or towel and

denatured alcohol or equivalent solvent

adhesive remover. Failure to do so may

result in adhesion issues due to mold-

release chemical contamination. Apply

adhesive according to instructions for

speciﬁc product in use. Be sure to follow

instructions based on substrate porosity

(porous or non-porous). See chart above

for reference.

When installing adhesive on steps,

be sure to leave a 1/2" - 3/4" space on

either side of step nose to accommodate

the Excelsior EN-610 Epoxy Nose Filler

Adhesive and avoid adhesive cross-

contamination. Prior to installing the

stair tread into adhesive, apply a 1/4" -

1/2" bead of the EN-610 to the interior

nose of the stair tread. All stair treads

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.

When using the overlapping seam

method, use Excelsior TP-620 1" tape

to adhere the back side of the stair

tread nose to the top of the riser below,

in order to provide a tight seam and

prevent a possible tripping hazard.

Roll material with a hand roller or

equivalent within 30 minutes of

installation, crossing in a perpendicular

direction after initial roll. Visually inspect

installation to ensure that material has not

shifted and that adhesive has not been

squeezed out of joints or compressed

onto surface.

Replace trowels and/or applicators at

recommended intervals to maintain

proper trowel ridge and spread rate.

When installing into adhesive using a

wet-set method, 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.
