I thought seam sealing was a gimmick until a rep in Tulsa showed me the numbers on a 6 month old stretch
I used to skip the seam sealer on smaller jobs to save 20 minutes and honestly figured nobody would notice either way. Last Tuesday a manufacturer rep named Carla walked me through a claim sheet from a Tulsa apartment complex where 11 of 14 seam failures traced back to unsealed edges after only 6 months of traffic. That one detail flipped my whole routine, and now the $8 tube goes on before the iron even cools. Any of you still skipping it on tight berbers, or is that just me being lazy on Friday afternoons?
Skipped it for years on tight loops and never had a callback, so I am not buying the panic. That Tulsa sheet is one building with one crew, and for all you know they let the edges sit damp or ran a crummy iron over them. Eleven failures sounds scary until you ask how many seams were in those 14 units total, because 3 that held prove nothing. Seam sealer on berber can actually wick glue up into the face and leave a visible line, which is a bigger problem than a frayed edge nobody sees under a couch. Carla gets paid to sell you $8 tubes, so of course her claim sheet points at the thing she sells. Show me the same numbers from three different complexes with different installers before I change my Friday routine.
