Seam Sealer Residue (Carpet)

Floor Detective® Claims and Conditions Guide

Summary

Seam sealer residue is an installation-origin condition that occurs when seam adhesive extends beyond trimmed carpet edges and transfers into visible face yarns during seam construction. Instead of remaining confined to edge encapsulation at the backing, adhesive migrates upward under compression and bonds pile yarns along the seam path. Observable effects may include stiffness, bonded tufts, darkened seam lines, altered reflectance, or localized texture change directly above the seam. In glue-down installations, exposed adhesive contamination may also attract soil and create visible dark seam-edge banding over time. Seam sealer residue develops during installation and does not result from normal traffic, maintenance, or environmental exposure. See also Seam Overlap, Seam Overheating, and Carpet Problems for broader context.
