Compound (nose filler) in cartridges, the first six inches (6”) of unmixed material from each
cartridge must be discarded to prevent bond failure and oozing of unmixed material down the
face of the riser! Only use the recommend ROPECC Epoxy Caulking Gun to apply ROPECC
Epoxy Caulking Compound. ROPECC Epoxy Caulking Compound is available in 1-quart and 1-
gallon pails and in 13.5-ounce dual cartridges. Shelf life is one year @ 70°F (21°C) in an
unopened container. Spread coverage is approximately 200 linear feet per US gallon on a
smooth substrate. Spread rate using the 13.5 oz. dual cartridge applicator with the required 1/2”
bead in the stair treads nosing is approximately 25 linear feet. Coverage will vary according to
the type of surface, surface texture, and adhesive temperature. To secure the stair treads
leading edge vertical nose to the riser, ROPECC Epoxy Caulking Compound must be applied in
a tight serpentine bead pattern covering the entire width and length of the stair treads nosing.
Secure stair tread nosing with Painters Tape until ROPECC Epoxy Caulking has dried. Remove
Painters Tape before exposing stair treads to traffic. 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 flooring material or surrounding area must be removed
immediately with a clean cloth dampened with denatured alcohol. DO NOT allow the adhesive
to cure on the surface of the tile. A bond failure will occur if the epoxy is not properly mixed to
one consistent color. Read all of the product and MSDS literature.
