3. Laying the boards
Calculate the surface area to be covered adding just a little because wastage due to cutting is minimal. Store the board's at an ambient temperature 24 hours before laying. For a better visual effect you should place the board's parallel with the longer side of the room but you could also lay them in the direction of the light coming in through the windows. To allow for expansion around the edges of the room, place 5 millimeter blocks upright all along the wall. For this type of board remove the long tongue with a cutting blade and put it in the corner against the blocks. Then place the next board in line with the first, making sure you leave some room for expansion along the wall. Tap gently with the rubber mallet on the board's to clip them together. At the end of a row measure the gap from the edge of the board to the wall block ideally at least 25 centimeters. To mark the cutting line, lay the next board against the previous one but with the two tongues touching. With the set square, mark and draw the cutting line in line with the end of the previous board.
Cut the vinyl once or twice with the cutting blade against a metal ruler then bend to
break it cleanly.
Lay the boards in rows one after another staggering each by a third of the board.
Offer up the next board and insert the tongue into the groove then push down to clip them together. Place the next board with its groove opposite the other board.
Complete each row in this manner.
