Old-timer at the supply house made me rethink my seam technique

Was picking up adhesive at Empire Flooring in Tulsa last Tuesday and this retired installer, must've been 70, watched me load my van. He said, 'Son, you're stretching seams like you're patching denim, not laying carpet.' Talked me through using a hot iron on the backing first for 10 seconds before trimming, not just after. Tried it on a 20 yard hallway today, flat as glass, zero peaking. Anyone else get tips from random old heads that instantly made their work easier?

That old iron trick works because it sets the backing before you cut, so the fibers hold their line instead of shifting on you. Did a hospital corridor last month with the same method, used a 4 inch seam iron at low heat for a few extra seconds on the backing, and it made the trim so much cleaner. The peaking usually comes from tension in the backing, not the face yarn, which is why so many guys miss it. Ran into an old timer in Arkansas who showed me the same thing with a seam roller, pressing down firm before the iron even touches it. Ended up doing a full set of offices that week without a single callback. Those old boys have forgotten more about carpet than most of us will ever know.
