No matter how well a vinyl floor is installed, bubbles can appear days, weeks or even years after installation. This is because moist air rises from below and gets trapped under the surface, causing a bubble. Here is the secret for removing bubbles in vinyl flooring: For small bubbles, an inch or less in diameter, use a large needle to prick the bubble, allowing the trapped air to escape. Then use a towel and a hot iron to heat and flatten the vinyl. Use a stack of books to weight it down until it rebounds. For larger bubbles, use a towel and iron first and carefully cut an X with a sharp razor knife. Pull back the triangle cuts and add floor adhesive. Press the cuts back in place and weight it down. Be sure to put down a sheet of waxed paper first so you don't wind up with a stack of books glued in place in the middle of your floor.
