Vinyl Floor Gap Fix. The floor gap fixer is the only tool designed for closing gaps in floating floors, without having to remove any molding. Just fill the gap, let it dry, then paint it with a color that matches the floor. You don't have to replace the entire floor when there are simple solutions to the gap issues.

The idea is that you stick the floor gap fixer on the board that has a gap at the end and wack it with the mallet. The installation is also incredibly easy and fast. Mallet made with heavy duty plastic, light weight and durable. Work your fingers or a prying tool into that gap and gently raise the plank or tile until it can be disconnected from its neighbors.
