Howdy folks! I'm in the process of installing a laminate floor in a 5 x 5 powder room-I'm about 3/4 done. When you walk on the new floor, it moves under your feet. The boards are locked together; the movement is hozizontal. The boards that I installed don't seem to be too bowed-some are a little bowed. I installed an underlayment and it was pretty flat, the only problem is that it retained a slight "curl" from being rolled up when I bought it. Also- The condition of the subfloor is good and firm. I have been using spacers (scraps of the flooring). I have also used a tapping block. Please help-any thoughts are appreciated!
