WPC planks are intended to be installed embossed side up. The unembossed surface is not to be used as a walking surface. This applies to all WPC planks.
WPC’s surface Decking boards are directional in manner. A notch has been added to one side of the planks. When installing planks, this marked edge must be laid to the same side for the entire installation for a consistent appearance. Similarly, Seventrust’s have one long beveled edge on the front and back. To ensure a consistent appearance from board to board, the beveled edge must be laid to same side. If you rip a piece, be sure to note the location of the bevel. See individual plank installation instructions.
The buildup or generation of static electricity is a naturally occurring phenomenon in many plastic based products such as carpeting, upholstery, and clothing, and can occur on alternative decking under certain environmental conditions.
