Facing the guide line, place the first plank at the lefthand end, tongue side facing the wall, starting 1/2" off the wall (Image 1). It is necessary to remove the tongue from all planks lining the starting wall. Use 1/2" spacers at the end and along the wall (two to a plank) while keeping the planks aligned with the string. Using a Natural Cork tapping block and a hammer, place the block flat on the floor, with the side up that is labeled: "This Side Up For Tapping On Groove". Tap on the block gently until the ends of the two planks are firmly joined, with the joint completely closed up (Image 2). Continue this process until you reach the end wall. Cut the last plank to fit allowing for a 1/2" perimeter expansion space on all sides.
Note: To do this, use a hammer and the special Natural Cork tapping block (Image 3). Using any other tapping block may result in damage to the cork wear layer. Don't attempt to knock the click joint into place with one hit. Once the two planks have "clicked" together, do not tap them again as this can cause the joint to be too tight and could result in peaking.
