deterioration of metal substrates. On an extremely smooth, non-porous, metal substrate, a
longer “tack up” may be required in order to prevent the adhesive from oozing between the
seams. Refer to 6.2.1. Caution: The installation of Stair Treads, risers or other flooring material
will not prevent deterioration of metal substrates from occurring.
6.3 Adhesive Application
6.3.1 ROP360 Acrylic Tile and Stair Tread Adhesive:
ROP360 Acrylic Tile and Stair Tread Adhesive is a solvent free, high strength, acrylic adhesive for
indoor installations over recommended and properly prepared concrete and wood subfloors only,
on grade or above grade. Use of this adhesive is limited to casual foot traffic, in areas where there
are no lateral shear stresses or rolling loads, nor in areas that will not be subjected to topical
moisture or liquids. (ROP360 must be used in combination with ROPECC Epoxy Caulking
Compound). Do Not use ROP360 to install Butting Stair Treads. For Butting Stair Treads
Installations, refer to ROP535U Adhesive and ROP435 Epoxy Adhesive Sections. 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 contaminates which could interfere with the bonding
process. Once cleaned with Denatured Alcohol, allow backing to dry completely before applying
recommended Roppe Adhesive or ROPECC Epoxy Caulking Compound and then test to
ensure a successful bond can be achieved. ROP360 Spread coverage using a 1/32” x 1/16” x
1/32” “U” notch trowel is approximately 200-300 square feet per US gallon on a smooth or non-
porous 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 (125-184 sq/ft/gal). Over porous substrates, allow
adhesive to “flash-off” for 10 minutes before installing. Over smooth or non-porous substrates,
allow adhesive to “flash-off” 20 minutes before installing. Approximate Working Time: 20-30
minutes (depending on substrate temperature, humidity & trowel size). At least 90% transfer to
the products backing is required.
Calculated VOC’s: ROP360 Acrylic Tile and Stair Tread Adhesive Calculated VOC’s according
to California SCAQMD Rule #1168: <13 grams per liter of coating. SCAQMD Rule 443.1: Grams
of VOC per Liter of Material: < 10 gram/liter.
6.3.2 Roppe 535U “Universal” Urethane Enhanced Epoxy Two-Part Adhesive:
ROP535U Universal Urethane Enhanced Epoxy Flooring Adhesive is a solvent free, non-
flammable, high performance adhesive for indoor installations over porous concrete, metal and
other non-porous or slightly flexing substrates, on grade, below grade, or above grade.
(ROP535U must be used in combination with ROPECC Epoxy Caulking Compound). 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 and a clean white cloth to remove contaminates which could interfere with
