Carpet Seaming
All seams must be properly prepared in strict compliance with carpet manufacturer
recommendations.
10.1
Trimming
Carpet seams must be trimmed using tools and techniques best suited for the carpet style
(e.g., loop-pile, cut-pile, cut-and-loop pile). Refer to Table I – Tools & Materials at the end of
this document. Trim edges far enough into the material to maintain the structural integrity of
the carpet and to seam without gaps or overlaps.
NOTE: 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. Trimming too far into patterned carpet will compromise pattern match. Contact
carpet manufacturers for specific seaming methods.
10.2
Sealing Edges/Seams
All seams must be sealed unless otherwise specified by the manufacturer. Regardless of
installation method, most carpet requires an edge protective material be introduced between
the edges to be joined. This material can be a liquid or thermoplastic and can be applied
using various procedures and techniques.
10.2.1
Edge Sealing
For carpet backings that require edge sealing, apply an appropriate seam adhesive covering
the thickness of the primary and secondary backing without contaminating face yarns on
both edges of the seam. This ensures that all edges trimmed for seaming are protected from
edge ravel. Allow seam adhesive to dry before proceeding with the installation to prevent
transfer to the face yarn.
