INSTALLATION
INSTRUCTIONS
- Condition
the area to be installed, adhesive, and carpet
to 65°F (18°C) or above for
48
hours before, during, and for 48 hours after installation.
- Subfloor
must be smooth, sound, dry, clean, and free dirt,
wax, polish, paint, and all other
foreign matter which may interfere in a good bond,
including curing agents and sealers.
- Always run
a calcium chloride and alkali test over concrete
on any grade level or any
other substrate over on or below grade concrete.
For accurate results, curing agents
must be removed in areas where tests will be run.
Moisture test results should meet
the flooring manufacturer’s recommendations
but should not exceed 5 pounds/
1000 ft2/24 hours. Alkali readings should be 5
to 9.
- Stir any liquid on the surface into the adhesive
and full spread using the recommended
trowel notching. Recommended trowel sizes are guidelines
only, and are minimum
requirements. Rough, porous concrete and heavily
textured carpet backings may require
deeper notches. A 100% transfer of adhesive into
the carpet backing, while maintaining full
coverage of the substrate, must be obtained.
- Before
installing stiff-backed carpet or installing over
nonporous substrates, allow the
adhesive to set open to develop some tackiness.
For all other carpet installations, install
the carpet immediately into wet adhesive. For felt-backed
sheet flooring, no open time is
required over concrete. For all other substrates,
allow adhesive to set open up to 10 minutes.
Do not let adhesive skin over.
- After appropriate
open time, cut, fit, and reposition within 40 minutes.
Working time will vary
based on job conditions, substrate, temperature,
and humidity.
- Roll
the flooring in both directions using the flooring
manufacturer’s recommended
roller (normally
75-100 lbs.). Stiff carpet should be re-rolled
in 2 hours.
- Cut and seal all seams as recommended
by the flooring manufacturer.
- Remove wet adhesive
residue using a clean, white cloth dampened with
soapy water.
Use mineral spirits for dried adhesive residue
carefully following warnings on container.
- Restrict
heavy traffic over carpet for 24-48 hours and do
not expose to water from
cleaning or other sources for a minimum of 30 days.
- Protect
sheet flooring installations when moving heavy
appliances and/or rolling loads.
