A 20 year guy in Boise showed me to backroll a seam before cutting, and it saved me 2 hours on a 3 room job
I was on a stretch job in Boise last month, 3 bedrooms plus a hall, and my seam kept peaking no matter how hard I pressed it down. The installer training me years back always said cut tight and stretch hard, but this guy watched me fight it for 20 minutes and just shook his head. He had me backroll the seam with a 75 lb roller before I trimmed anything, then cut it after the glue set up for about 15 minutes. The seam laid flat on the first pass, no peaking, no redoing it, and I finished the whole house about 2 hours faster than normal. I've done maybe 40 seams since then and only had one bubble. Anyone else backroll before trimming or am I the last guy to hear about this?

Backrolling before trimming saving you 2 hours on one job sounds like a good day, not a new rule for everyone. I've seen guys swear by it and guys who cut first and never get a peak either, so a lot of it comes down to the glue, the backing, and how long you actually let it set. You say 15 minutes, but on a cold floor or with fast grab glue that window is all over the place. One bubble out of 40 seams is fine, but that's also about normal for a guy who's been doing this a while. Glad it worked for you, just don't toss your old method in the trash over one Boise guy.
