Fixing a sheet-flooring bubble

摘要

I had installed a Marmoleum floor, but after several weeks, a bubble formed where the glue hadn't held. I didn't want to cut an access slit for additional mastic, but the bubble was a good 2 ft. from the nearest wall. It occurred to me that I might gain access by removing the heat register, then prying up the flooring all the way to the bubble.
