3. INSTALLATION
The installation of Burke Thermoplastic Rubber and Vinyl
Stair Treads should not begin until the work of all other trades
has been completed, especially overhead trades. Areas to
receive stair Treads shall be clean, fully enclosed, weather-
tight, and maintained at a uniform temperature of at least 70°F
for 24 hours before, during, and after the installation is
completed. The stair treads and adhesives shall be conditioned
in the same manner. Stair steps shall be smooth, flat,
permanently dry, clean and free of all foreign material, such as
dust, paint, grease, oils, solvents, curing and hardening
compounds, sealers, asphalt, and old adhesive residue. Stair
Treads may be installed on any smooth, dry interior step. Do
not install on exterior steps subject to weather. Stair shape
shall conform closely to stair tread contour, especially where
the flat part of the tread joins the nosing. An epoxy caulking
nose filler shall be applied to ensure a tight fit and eliminate
any open spaces between the step edge and stair tread nosing.
Stair Treads shall be trimmed to within 1/16" of the stringer to
allow for expansion. Adhesives shall be applied per Burke’s
instructions. Stair Treads shall be rolled, with a J-hand roller,
after installation, to ensure proper bonding.
