Carpet Installation Check off List
1. Newly poured concrete floors generally will take 30 day
s per inch to cure. Moisture should
not exceed 5 lbs. /1000sf per 24 hours or 80% relative humidity as determined by current
ASTM standards. If the results are more than 5 lbs. or higher than 80% RH, do not proceed
with the installation. NOTE: EcoFlex NXT® carpet tiles installed using the FlexLok®
tabs can be used for installations up to 99% RH. Gypcrete or substrates with excessive
dust must be cleaned, and then primed with an approved primer such as a latex milk
additive.
2. The floor and room temperature must be acclimated by maintaining the temperature at 65°F
and 85° F, and the humidity between 30% and 65%, for at least 48 hours before and during
installation. In addition, the carpet and adhesive should be stored under these conditions for
at least 24 hours before installation. The installation site must be acclimated with HVAC in
operation.
3. When the installation is complete, the jobsite must be maintained at normal service
temperature and humidity.
4. Pre-existing adhesive must be 90% removed to have only trace amounts of adhesive
showing (10% or less of the old adhesive showing on the subfloor) or hand scrape /
mechanically sand smooth and apply Optiseal prior to any installation of Mohawk Group’s
modular carpet. Any cut back should be scraped smooth and sealed as well. See note #1.
5. Mechanically remove all wax, dirt, grease and paint. DO NOT use solvents to clean the
floor. DO NOT use oil based sweeping compounds. Fill cracks more than 1/16” wide with a
Portland or cement based patching compound. The floor must be flat to within 1/8” in 10
feet. Use leveling compound when required. Patched areas may need to be primed (consult
patch manufacture for requirements) with an approved primer. DO NOT install over resin or
silicate based curing compounds.
6. Inspect all carpet prior to cutting and contact your sales representative before installing the
carpet if you discover any problems. No claims will be allowed for visible defects after the
carpet has been cut and installed.
7. Never cut carpet over carpet as this can result in over penetration of the blade and cutting
loops on the lower carpet.
8. Carpet should be protected from heavy traffic and construction dust with a non-staining
building material paper. Never use plastic sheeting as it will trap moisture and prevent
proper curing of the adhesive. Plastic may also leave residues that can result in rapid
soiling after removal.
9. If any of the above conditions are not attainable, contact Mohawk Group Technical Services
at 800-833-6954.
Please Note
1. Asbestos-containing floor tiles, any adhesive possibly containing asbestos, or other
asbestos- containing floor coverings require special preparation, handling, and removal
procedures. Consult the appropriate local or state authorities or the Resilient Floor
Covering Institute before disturbing any suspected asbestos-containing material.
2. Installation of Mohawk Group’s modular carpet on a floor outside the scope of the
guidelines in this document will void all applicable warranties.
3. The Mohawk Group is not responsible for any product failure due to improper floor
preparation and/or installation procedures. The required adhesives are Mohawk Group’s
family of adhesives.
4. When installing carpet tiles over raised access floor panels, start installation by overlapping
the access panel joints to prevent the seams of the tiles from lining up with the access
