manufacturer. If recommendations are not available, refer to the general
minimum guidelines in Table II.
13.4 Cushion to Substrate Installation
Spread adhesive uniformly over the substrate with the specified trowel or other
application procedure. After sufficient open time, the cushion is to be installed into
the adhesive in a manner that minimizes air pockets. Proper open time is
critical for a successful installation.
NOTE: For cushion to substrate, adhesives, application methods and
spread rates are different from carpet to cushion installation methods.
Refer to manufacturer’s installation instructions.
13.5 Carpet to Cushion Installation
When applying 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 placed into the adhesive and rolled
with the appropriate roller. Proper open time is critical for a successful
installation.
NOTE: When spreading adhesive over cushion, excessive trowel
pressure reduces effective adhesive coverage rate.
13.6 Seam Cutting
Although “row-cutting” both edges is preferred, other trimming techniques may be
more suitable on some carpet. Many carpets do not lend themselves to all methods
of cutting. Contact carpet manufacturers for specific seam cutting methods.
13.7 Edge Sealing
All seams must be sealed unless otherwise specified by the manufacturer. Refer to
Section 10.2.
13.8 Seaming
Hot melt seaming is required for double glue installations unless otherwise
specified by the manufacturer. Do not use silicone coated seaming tape.
Refer to Section 10.3.1.
