Adhesives and Trowel Notch Sizes
When applying cushion to substrate 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 –
Trowel Size Minimum Guidelines at the end of this document.
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 – Trowel Size Minimum
Guidelines at the end of this document. 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.

Seam Cutting
Althoughrow-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
Broadloom Carpet > Carpet Seaming > Sealing Edges/Seams section of this document.
