Installation procedure

1,Fixed WPC keel:WPC keel or Steel Keel evenly arranged on the cement floor,we recommend the space between joists is L=300-350mm(Middle to Middle). Using electric drill to lead hole on keel, then screw into drill hole, fix keel on cement ground, nail head should be rotated into keel, do not expose outside, otherwise the floor layout may be uneven.

When installing WPC  keel, need to make concrete ground level off.When the ground is found uneven,Just make the ground level up to a certain standard,The preliminary treatment of the ground is very important.Because when laying decking, the specification of keel  is consistent, if the ground does not make level, when laying WPC decking, can cause decking uneven or the phenomenon with different keel heights.

If The thickness of concrete is not less than 8mm, then, we can use  expansion screws directly to fix the wpc keel to the concrete ground.

After the keels are  laid, some Keel  bottoms  and the ground has a gap, at this time also need to take cardboard or wood pieces put inside it.
