Quick Clip System – Laying the Boards
On a concrete or screeded floor, use an intermediate underlay layer to ensure good walking comfort and sound step reduction with the moisture barrier. We recommend that the boards are laid parallel to the longest side of the room. Roll out the underlay at right angles to the direction that the boards are going to be laid. Turn the board over and tap the end of the clip with the barb(s) into the groove on the back of the board, so that the plain end clip points in direction of the tongue, which is the laying direction. Lay the board in place, tongue pointing away from the wall. Continue to the end of the row, gluing their header joints. Boards must never be glued along the length. Cut the last board to length. Use the off cut to start the next row. To lay subsequent row of boards, tap the joints together, using a wooden block working evenly along the boards. Lay the boards in a random pattern. Distribute the header joints as far apart as possible. The distance between board joints and in two successive rows should be at least 2.5cm. One row of boards should not be in line with the starve joints in a neighbouring row but must be spread apart as far as possible. First and last clips: max 8cm from the end of the board. Other clips spacing: first and last row 40cm centres. All other rows 70cm centres for residential and 50cm centres for commercial. The clips must be staggered (in line) by approx 5cm. The first row of boards are installed leaving an expansion gap at the wall of 1.5mm for every running metre of floor width at each side, with a min expansion gap of 1.0mm for every metre of floor length at each end of the min gap of 15mm.
