Pro tip: That builder complaint about my seams changed my whole approach

Had a builder call me out on a job last year in Medford. Said my seams were visible under the can lights even though I thought they looked fine. I was using a standard stair tool and not putting enough pressure on the edge before the glue set. Now I go back over every seam with a weighted seam roller and wait a full 3 minutes before I stretch the next piece. The difference is night and day. Any other installers have a trick for hiding seams under direct light?

The seam roller trick is a good one. What really helped me was switching to a heat gun instead of a torch for softening the adhesive. The torch gives you such a narrow hot spot that you end up rushing the edges. With a heat gun you can warm a wider area evenly and that gives you more time to really work the seam flat before it sets. I also started using a small rubber mallet to tap down the seam edges after rolling. It sounds basic but it makes a big difference under those unforgiving can lights.

120 degrees is the sweet spot on my heat gun and I never go past 3 inches from the vinyl. I learned that the hard way when I melted a seam in my dining room and had to peel the whole sheet back. The rubber mallet trick is smart but I take it one step further - I use a seam sewing wheel after the mallet, the kind upholsterers use for tufting. It punches tiny holes along the seam edge that let trapped air escape during cooling. That little detail has saved me from bubbles under track lighting more times than I can count.
