Notes:
1, WPC products could be slightly in-tumescent after heating and water absorption, so must retain 3-5mm a small gap between main building when placing the keel.
2, WPC products are hard and brittle, expansible screws must be bolted 70mm from the head to the end. (must hit with a twist drill a hole before bolting the screw).
3, The spacing between 2 expansible screws should be 400-500mm.
4, First piece floor installation, use the plastic clip (clip should be flush with the keel)
5, Drainage must be installed after keel fixed, in order to avoid floor damaging by the water.
