Installation Instructions

14.4 Layout –Where applicable, allow for pattern repeat. Align all carpet breadths to

their proper position and trim seams. Take care to avoid cutting into cushion under

seams.

14.5 Adhesives and Trowel Notch Sizes - When applying cushion to floors and carpet

to cushion, select the appropriate adhesive and trowel notch size recommended by

the carpet, cushion and adhesive manufacturer. If recommendations are not

available, refer to the general minimum guidelines in Table II. Spread adhesive

uniformly over the cushion with the specified trowel or other application procedure.

After sufficient open time, the carpet is to be pressed into the adhesive and rolled

with the appropriate roller. Proper open time is critical for a successful installation.

Note: excessive trowel pressure causes cushion to expand into the trowel

notch reducing effective adhesive coverage rate.

14.6 Seaming - A variety of seaming options exist. Consult the cushion and carpet

manufacturer for specific recommendations.

14.7 Rolling – Refer to Section 13.6.

15. Attached-Cushion Installations

15.1 Relaxing/Conditioning Carpet – Refer to Section 7.11.

15.2 Carpet Layout - Refer to Section 9.2 (Direct-Glue Installations)

15.3 Floor-Applied Adhesive Installations - Use the carpet adhesive and seam

adhesive recommended by the carpet or adhesive manufacturer. Also, refer to

Table II.

15.3.1 Trowel Notch Size - Refer to Table II

15.3.2 Open Time – Allow adequate open time for adhesive. Open time varies depending

upon environmental conditions and the adhesive type.

15.3.3 Installation Procedures – Cut seam edges with appropriate tools based on carpet

manufacturer recommendations. Trim edges to eliminate possible height variation at

the seam. In the case of woven goods, carefully refer to the manufacturer’s

recommendation for that specific style. Seal cut edges at seams with proper seam

adhesive applied as recommended by the carpet or adhesive manufacturer. Roll

installed carpet according to manufacturer recommendations.

15.4 Pre-applied Adhesive Systems (“peel-and-stick”) - Pressure sensitive adhesives

sometimes are applied to attached-cushion backings during manufacture. Backings

of this type have special floor preparation requirements. Consult the carpet

manufacturer for recommended installation procedures and the use of primers, if

needed.
