Installation Instructions

CRI 105 - STANDARD For INSTALLATION of RESIDENTIAL CARPET

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 recommendations for patch
