You don't need the pros' special tools—laminate adhesive and a J-roller—to stick peeling Formica back in place. Use a heat gun, or even a hair dryer, to gently heat the laminate and soften the old glue underneath. Whack it with a rubber mallet or a hammer cushioned by a block of wood. Weigh it down for about an hour with a stack of heavy blocks while the laminate cools and readheres to the substrate.
