When installing laminate flooring, the first step is determining how much flooring you need. Measure the floor area you plan to cover and add then 10 percent to allow for waste. After buying the flooring, store it inside your house to acclimate it to room temperature. This will help prevent it from accumulating moisture as well as reducing expansion and contraction.

Remove the shoe molding from around the baseboard and any doors in the new floor area. The flooring planks will need additional clearance to fit under existing door frames. Place a piece of underlayment and laminate flooring next to the jamb to determine the appropriate height and cut out the desired area of the frame with a handsaw.

If your laminate floor is going directly over a concrete slab, apply a polyethylene plastic vapor barrier first. For all spaces, install floor underlayment. This comes in large rolls or as separate pieces that can be taped together.Tape the pieces together to prevent them from shifting. Create an expansion gap between the underlayment and the walls by using spacers. In addition to reducing noise, the underlayment cushions the laminate flooring so it is more comfortable to walk on.
