To push a separated laminate flooring plank back into place, unroll a piece of duct tape about a foot long (don't cut it off the roll) and firmly stick it along the floorboard near the gap. Step on the tape attached to the floor to hold it into place, and pull the roll of duct tape up, creating a line of tape that's perpendicular to the floor.

Once the floor planks have been tapped into place, you can use a pull bar to complete the fitting process. A pull bar is a tool designed to help you secure the laminate pieces together. To use a pull bar, start by inserting it between the two laminate pieces and then slightly pulling them apart.

The best way to fix laminate flooring that keeps leaving a gap during installation is to lift the shorter edge (the tongue) up at a 30-degree angle to the longer edge (the groove). Then lightly tap the angled board toward the second board until it seeds a little more into the flat board.
