Is there a trick to set laminate flooring?

Let the boxes sit in the room for a couple of days first so the boards acclimatise. Underlay down, start against the longest straight wall, and leave a gap round every edge - about 8-10mm, use spacers. Laminate expands and if it touches the wall it'll buckle. Stagger the end joints so no two rows line up, at least 30cm apart. The last row nearly always needs ripping to width, measure at both ends as walls are rarely straight.
