To install floating laminate flooring, acquire the right measurements for both the width and the length of the room. Determine the total floor covering required by working out the area of the room. Add approximately 10 percent to the estimated area to allow for wastage. Carefully lay a layer of underlayment starting from one corner following the direction of the new floor.
Make the underlayment fit around the door jambs by cutting it using a utility knife. To create a moisture barrier on the floor, set the foam mat in place with the plastic side down, and use polyethylene tape on the seams.
Leave a 1/4-inch space between the flooring edges and the wall during the floor installation. This gives enough room for both contraction and expansion during the weather changes. Install the first row by placing the planks with the tongue side facing the wall. Fit the tongue and the groove together by putting the first and the second board at an angle.
Tighten the seams by carefully placing the seams in the required positions using a hammering block. Using a small pry bar, force the last snug against its neighbor to avoid gaps when fitting in the last plank.
Check the state of the last row. If it is narrower than the plank width, cut off the tongue of the plank with a sharp chisel until it fits. Cover the gaps by adding the shoe molding and baseboards.
