HED INSTALLATION
|
Harsh Environmental Deckingâ„¢ (HED) is specifically designed to be
installed by the handyman or contractor. HED is an extremely tough weather
resistant polyvinyl-alloy formulation.The interlocking modular deck planks
are fastened to the deck's structural framework using stainless steel
screws with rubber-washer (ie. same type screw normally used with corrugated paneling).
Slots in the fastening flange accomodate for linear material expansion. Decking planks
butted end to end must retain a spacing gap of 1/16" per every 12'
to compensate for material expansion is hot climates. Deck framwork supporting joists
should not exceed 16" o/c.
Plank installation begins by snapping a chaulk-line across the top of the deck joists
which provides a good straight starting line to align and fasten down HED Starter
Rail. Apply the 1" screws at every joist. Continue installing HED Decking Planks using
chop saw to cut parts. As in any decking procedure, it is important
to always keep the board planks straight. It is a good practice
to keep monitoring the straightness by using a string usually every 5 rows.
The final decking plank width may be ripped using skill saw. When notching a plank
to fit around a deck post member, use a 1/4" drill in the corners prior to sawing
out the notch. All inside corners should maintain a soft radius to eliminate all stress points.

Upon completion of decking assembly, snap a stringline to set-up for any
required edge trimming. After straightening up the sides of the deck, snap another
stringline1 1/2" inboard to create an alignment line for the Edge Cap part to be
pushed up to. You want the perimeter deck Edge Caps to look very straight. Edge
Caps are applied to the perimeter using an elastomeric urethane or butyl adhesive.
Apply the adhesive liberally to the inside top and bottom surfaces of the Edge Cap
using caulking gun and roughly smooth out the adhesive with finger. Slide part on
decking and align to chaulklne. Use tape to secure part position during the adhesive
cure time.
