o On adjustable nose treads, either ROP535U, ROP435, Quik-Stik Adhesive Tape
or 3M 2141 Contact Adhesive (always follow manufacturer’s recommendations,
cautions and warnings etc.) can be used on the inside nose face and riser
interface to secure the vertical nose at the proper angle. Pre-cut and fit the treads
prior to spreading adhesive. Scribe and fit treads to the proper step depth and
length. Then thoroughly clean the stair tread nosing and riser with Denatured
Alcohol (always follow manufacturer’s recommendations, cautions and warnings
etc.) and a clean white cloth and allow to dry. DO NOT use fans to expedite the
drying of adhesive.
o Caution: See Section 6.4.4 for instructions, cautions and warnings regarding the
installation of rubber stair treads, risers and stringers with Roppe’s Quik-Stik
Adhesive Tape before proceeding with installation.
After the stair tread has been scribed, trimmed and fitted and thoroughly cleaned with
Denatured Alcohol (always follow manufacturer’s recommendations, cautions and warnings
etc.), apply ROP360 Acrylic Tile and Stair Tread Adhesive or recommended adhesive depending
on substrate or installation type, with recommended trowel. DO NOT allow ROP360 or
recommended adhesive/tape to come in direct contact with the portion of the step nosing where
ROPECC Epoxy Caulking Compound will be applied. Coverage will vary according to the type
of surface, surface texture, spreading angle, and adhesive temperature. When installing Square
Nose Stair Treads, start 1/4” from the steps nose, spread the adhesive evenly using the
recommended trowel notch noted in the adhesive section, leaving no puddles of adhesive.
Caution: Spreading adhesive on a large number of steps and treads could possibly allow the
adhesives to cure or setup before the treads are installed which would result in a bond failure.
For porous substrates, allow the adhesive to “flash off’ for approximately 10 minutes before
installing the tread, however do not allow adhesive to dry or skin-over. On smooth substrates,
allow the adhesive to flash-off longer, but do not allow adhesive to dry or skin-over. Caution:
Open time and curing characteristics will vary upon the type of substrate, substrate temperature,
ambient temperature, humidity, and proper conditioning of the adhesive. Allowing the adhesive
to remain open too long will result in a bond failure. After applying ROP360 Acrylic Tile and Stair
Tread Adhesive, at least a ½” bead of ROPECC Epoxy Caulking (nose filler) Compound is then
applied directly inside the nose of the square nose stair treads, prior to installation, and when
uniformly and properly applied fills slight voids or gaps between the internal nose angle of the
tread and step edge, developing a strong bonding support between the two surfaces. ROPECC
Epoxy Caulking Compound is available in cartridges and quart and gallon containers. ROPECC
Epoxy Caulking Compound quart and gallon containers consist of two units, Part A (epoxy
resin) and Part B (hardener). DO NOT mix partial units of this adhesive, because the ratio of
Part A to Part B is not 1:1. Open the two units and pour all of Part B into Part A. Mix the
combined parts with the furnished paddle using a rotary motion while at the same time lifting
from the bottom. A slow speed, 200-RPM maximum drill with an attached mixing paddle may
also be used. Mix thoroughly 4 minutes, ensuring that the adhesive is uniform in color with no
streaking. Caution: Higher mixing speeds and/or longer mixing time will reduce the open time
and can cause premature curing of the adhesive; however, if not mixed long enough, the
adhesive will not properly cure. Once mixed, the epoxy nose caulking must not be allowed to
