Worked on a test to repair a visible seam on some newly installed commercial carpet. It was some unitary backed loop pile commercial carpet.
It's about 4 feet in length where it's not quite up to par. The seam is a good 25 feet long... and not sealed .
Seam has a 1/32nd gap in that section and part of the seam has the row split in half. Probably cut from the top because rows are hard to follow.
I split one row off a scrap and carefully coated the raw backing edges with contact cement to seal them..... I let that set for an hour to dry.
Then I cut a row out of the middle of the test piece and ran a bead of carpet seam sealer (solvent based) down inside the gap and carefully poked the sealed row into the gap. Looks pretty good. I used seam sealer inside the gap because it's more forgiving than contact. It gave me more play time to work the piece into place.
