Q: Over the past five years, I’ve built more than 30 laminate countertops, and I’ve never had any problems with them. Recently, however, one of my countertops started to bubble in a few places about five weeks after I built it. I tried taking an iron and heating the laminate, then flattening it with a J-roller until the laminate cooled. This worked, but for only about a week. What could be causing this to happen? And what can I do to fix this problem?
