CRI 105 - STANDARD For INSTALLATION of RESIDENTIAL CARPET Copyright © 2015 by The Carpet and Rug Institute, Inc.
General Requirements
indoor carpeted areas to fall below 50º F (10º C), regardless of the age of the installation.
If these conditions are not attainable, contact the flooring manufacturer for warranty
implications.
NOTE: If the above conditions are not met, installations may be susceptible to moisture
related failures including but not limited to dew point condensation.
7.3
Ventilation
During installation, maintain air circulation by operating the HVAC system.
NOTE: For acceptable indoor air quality, fresh air ventilation in residential spaces is
recommended to conform to current guidelines specified in ASHRAE Standard 62
published by the American Society of Heating, Refrigerating and Air Conditioning
Engineers (www.ashrae.org).

Substrate Preparation
Substrates are required to be structurally sound and free of foreign substances that will
compromise the carpet or its installation. Patching compounds are required to be suitable
for application. Select polymer-fortified patching compounds according to the carpet
manufacturer’s instructions. (Refer to current version of ASTM E1155).
NOTE: Patched areas may be porous and highly alkaline, which will prevent adequate
adhesive bond. For best results, prime patched areas. Consult patch manufacturer for
primer recommendations and compatibility with adhesives.
8.1
Concrete
Concrete must be cured, clean, dried and tested in accordance to the General
Requirements > Testing section of this document. If the carpet is to be installed using an
adhesive, the concrete should be free of dirt, grease, oil, curing or parting agents, and
other contaminants, including sealers, that may interfere with the bonding of adhesive.
NOTE: It is not recommended to chemically treat (abate) substrates. These chemicals are
difficult to completely remove and will adversely affect new adhesive and carpet. Contact
your manufacturer for specific information.
Whenever a powdery or porous surface is encountered, a primer/sealer compatible with
the adhesive should be used to provide a suitable surface for the glue-down installation.
Patching of cracks and depressions shall be made with an appropriate and compatible
latex or polymer fortified patching compound. Do not exceed manufacturer’s
