A: Flex Tape® isn’t designed for high pressure applications but considering the cost of a new air mattress, it may be worth a try. Start by deflating the air mattress or inflatable. Be sure to start with a clean and dry surface. It’s recommend to wipe the surface with rubbing alcohol. The double patch method would work best here. Cover the leak with a small patch of Flex Tape®, slightly bigger than the hole or tear in the air mattress or inflatable. Apply this patch using firm pressure removing all air bubbles. Next, take a second piece of Flex Tape®, larger than the first, and place it over the smaller piece, smoothing out all air bubbles. Its bond will increase with time and pressure and in some cases, may need up to 24 hours to reach maximum hold. Flex Tape® may not bond with all materials. Always test before use.
