the bonding process. Once cleaned with Denatured Alcohol, allow backing to dry completely
before applying recommended Roppe Adhesive or ROPECC Epoxy Caulking Compound and
test to ensure a successful bond can be achieved. The ROP535U must be used for installations
in areas where the stair treads will be subjected to lateral shear stresses and/or rolling loads,
over metal, other non-porous substrates, slightly flexing substrates and in areas subjected to
topical moisture or other liquids. Butting Stair Tread installation must be installed with ROP535U
with a minimum of six (6”) inches of epoxy applied on either side of the seam and stair tread
nosing to ensure the seams integrity. The remaining portion of the stair tread can be installed
with ROP360 or the specifically recommended Roppe Adhesive depending on substrate and
stair tread type. ROP535U spread coverage using the 1/32” deep x 1/16” wide x 1/32” “U” notch
trowel is approximately 125-185 square feet (Part A & B Mixed) per US gallon on a smooth
substrate. Coverage will vary according to the type of surface, surface texture, spreading angle,
and adhesive temperature. Note: Over extremely porous or rough concrete, a 1/16”x 1/16” x
1/16” Square notch trowel may be required (100-125 sq/ft/gal). Caution: If too much adhesive is
applied, air-bubbles, oozing and telegraphing may occur along with adhesive displacement
when the floor is rolled or exposed to rolling loads resulting in loose and unsightly areas.
Therefore, test trowel size and flooring prior to installation to avoid the above noted potential
problems. Adhesive is available in 1-gallon units. Shelf life is one year @ 70°F (21°C) in an
unopened container. Although the epoxy components are non-freezing, the adhesive must be
allowed to stabilize to ambient temperature before mixing. Any adhesive on the surface of the
tiles or surrounding area must be removed immediately with a clean white cloth dampened with
warm soapy water or denatured alcohol. DO NOT allow the adhesive to cure on the surface of
the flooring or stair treads. A bond failure will occur if the epoxy is not properly mixed. Read all
of the product and safety information concerning the adhesive and any other chemicals or
cleaning agents prior to installation.

6.3.3 ROP435 Solvent Free Epoxy Flooring Adhesive
ROP 435 Solvent Free Epoxy Flooring Adhesive is a solvent free, non-flammable, high
performance epoxy adhesive for indoor installations over porous and non-porous substrates
(excluding metal) on grade, below grade, or above grade. (ROP435 must also be used in
combination with ROPECC Epoxy Caulking Compound).Butting Stair Tread installation must be
installed with ROP435 or ROP535U, depending on substrate type, with a minimum of six (6”)
inches of epoxy applied on either side of the seam and stair tread nosing to ensure the seams
integrity. The remaining portion of the stair tread can be installed with ROP360 or the
specifically recommended Roppe Adhesive depending on substrate and stair tread type.
Caution: Before applying the recommended Roppe Adhesive or ROPECC Epoxy Caulking
Compound, the stair tread, riser and stringer’s entire backing must first be thoroughly cleaned
