Achieve Even Gap Spacing
e DeckWise® hidden deck fastening system is one that allows you to run the
screws straight down when installing composite or PVC decking. is installation
technique allows the composite or PVC decking to expand and contract on
its length. is is optimal with composite and PVC decking because unlike
hardwoods, this material tends to expand on its length rather than width. Since
they do not move on their widths like hardwood decking, your gap spacing will be
maintained through the life of the product.
Prevent Nail Pops and Mushrooming!
Why would you want to blemish your brand new deck surface by running
screws through the face of your composite or PVC deck boards during
installation? Face screwing this material causes the surface to “mushroom”
around the face driven screw. is creates a deck surface that is riddled with
unattractive aws. is method also weakens the screws because, as the
composite material naturally expands and contracts, the screws get rocked back
and forth and loosen their hold on the joist.is process almost always leads to
the screw head popping out or worse, the screw snapping.
