type roller within 15 minutes after the tread has been installed. Caution: DO NOT roll the tread
nose. Rolling the tread nose will squeeze out the epoxy nose caulking. The rolling time may
need to be adjusted to climatic conditions. Conduct a visual inspection during the rolling process
to ensure there has been no shifting of the treads and that there is no adhesive on the surface
of the tread. DO NOT wait until the entire installation is completed before rolling as the adhesive
may have surpassed the open time and be cured. Roll and cross roll a second time with a J-
type roller approximately 30 minutes after the initial rolling. Notice: If the tread slips forward
causing an air space at the nose, cracking at the nose will eventually occur. At the top of the
stairs, cut the final tread off along the back of the design and dry fit it on the landing. Ensure that
the color match of the tread and landing tile is acceptable. Notice: On landings, use
recommended stair nosing and install with recommended adhesive depending on substrate
type. If stair tread is be utilized instead, there may be a height difference between the stair tread
and landing tile. It is the installer/floor contractor’s responsibility to ensure a smooth transition
between the stair treads and landing tile by either utilizing Roppe’s Sub-Floor Leveler, utilizing a
portland-based underlayment or by sanding either the back of the stair tread or landing tile.
Install the final tread and landing tiles. There is to be no foot traffic on the treads for at least 48
hours and no wheeled conveyances for at least 72 hours. Do not clean stair treads or other
associated products for 72 hours. Allowing traffic on the treads before the adhesive hardens will
cause the treads to slip forward creating an air space at the nose, which will cause cracking of
the nose at a later date. Protect treads against mars, indentations and other damage. Do not
flood the stair treads during cleaning, which will have an adverse effect on either the adhesive,
Quik-Stik Adhesive Tape or ROPECC Epoxy Caulking Compound used resulting in a failure.
6.4.2 ROP 435 Solvent Free Epoxy Flooring Adhesive and ROPECC Epoxy Caulking
Compound for Individual and Combination Rubber Stair Tread & Riser Installations
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. When installing over metal and other
slightly flexing substrates, ROP535U must be used. The ROP435 Solvent Free Epoxy Flooring
Adhesive must be used for installations in areas where stair treads will be subjected to lateral
shear stresses and/or rolling loads, and most other non-porous substrates. 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 with Denatured
Alcohol (always follow manufacturer’s recommendations, cautions and warnings etc.) and a
clean white cloth to remove the factory mold release agent applied during the manufacturing
process, along with any other contaminates which could interfere with the bonding process.
Once cleaned with Denatured Alcohol(always follow manufacturer’s recommendations, cautions
and warnings etc.) , 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. DO NOT allow ROP435 to come in contact with the portion of the step nosing where
ROPECC Epoxy Caulking Compound will be applied. Caution: For installations requiring butting
treads, the treads must be specially ordered from the factory. Roppe will make the necessary
manufacturing changes to ensure butting installation requirements. Butting tread installation
