Notice Before Installation

1. Before fixing, keep the concrete ground dry, clean and smooth. The decking boards are especially for decking. It is forbidden to  put to other use, such as construct support, connector , or to be some parts of other  load-bearing.

2.The moisture absorption rate of WPC materials is 0.2%, While expansion rate is  around 0.5%. Keep the necessary interspaces according to the length and width during  installation. Keep the decking smooth, If have to install the decking boards at some active place, do not fix too tight. In order to avoid storing water, the groundwork needs  to be slightly lean. We suggest to install the decking under 25℃ or avoid to exposing to  the hot sun in order to reduce the influence from thermal expansion and contraction.

Installation Steps

Step 1: Fixing joist on the ground

Before fixing the joist, make sure the concrete ground are clean and dry. Pre-drill with a  drill-bit on the ground and joist, and put the plastic expansion plug into the holes, then fix the  screw on it. The space of two holes should be less than 30cm. The maximum distance between  two joists should be 30cm. Leave at least 15 mm for the space of end-gap to solid structure if it  has.

Step 2: Fix the deck to the joist

Before fixing the decking, make sure the joists are clean and smooth. At the joint, leave a  distance of 5mm for expansion. Please don’t forget to leave at least 15mm for the space of  end-gap to solid structure if it has. In order to keep the board from longitudinal shift because  of the thermal expansion and contraction, we suggest fixing one screw on the edge groove of  each board into the joist (only one screw for each board).
