When putting down laminate flooring, you have to be sure to stagger your joints. By ‘stagger your joints', I mean that you cannot have your cut plank ends lining up to one another. You see if you want your floor to stay on the ground for a long life you need to get the best lock possible between pieces.
If you lined up your cuts, all of your floor would rely on the same joint spot to resist lifting. When you stagger your joints, you will have many different joints from which you will get better strength out of your whole floor. Staggering means more necessary cuts in your laminate flooring planks, but it is a step you cannot skip.
