Installation Instructions

CRI 105 - STANDARD For INSTALLATION of RESIDENTIAL CARPET

General Requirements

8.4

Resilient

Installing carpet over resilient flooring may be acceptable as long as the resilient flooring is

securely bonded to the substrate and all waxes, sealers, floor finishes and other foreign

materials have been removed. It is not recommended to install over floating, perimeter

bonded or cushion-backed sheet goods.

NOTE: Some sheet vinyl, resilient tile and cut-back asphalt-based adhesive may contain

asbestos and/or crystalline silica. Recommended work practices prohibit sanding, dry

scraping, bead-blasting or mechanically pulverizing resilient flooring, backing or lining felt.

Do not use powered devices that create asbestos dust when removing “cut-back” or asphalt-

based adhesives. Removal procedures must comply with federal, state and local government

agency regulations covering the removal and disposal of asbestos-containing materials

(ACM).

8.5

Radiant Heat Floors

Radiant-heated floors require special consideration in the selection of carpet, carpet cushion,

installation methods and adhesive.

Unless absolutely certain about the location and depth of heating components, use adhesive

to attach tack strip and transitions.

The maximum surface temperature of radiant-heated substrates should not exceed

85ºF/29ºC.

Refer to the Radiant Professionals Alliance for additional information.

8.6

Asphalt

For approved flooring materials, it is required that asphalt surfaces be clean, dry, free from

excessive oil and grease, and in good condition. Cure new asphalt for at least 90 days, or

longer, depending upon weather conditions. Follow adhesive manufacturer’s requirements.

8.6.1

Terrazzo, Ceramic, Marble, Slate and Other Nonporous Surfaces

Remove surface finishes and abrade flooring surfaces to ensure adhesion. Grout lines must

be filled and flush with flooring material surface. Ceramic or other surfaces may require the

use of a primer to ensure proper adhesion. Slate and brick surfaces may be too rough and

uneven for most installations and may require the use of a self-leveler or smoothing before

installing carpet. Attention must be given to the “open time” requirements of the adhesive

manufacturer when adhering carpet to these surfaces.
