DECKING
Installing Angled Deck Boards in Corners
ALWAYS start in corner with a small triangular piece 
of decking at 45° and work outwards. Install Trex 
Hideaway Hidden Fasteners 1/2" (13 mm) off center 
to keep fastener screws in middle of joists.
How to Butt Seams
1. Install 10"–12" (254 mm–305 mm) framing 
boards along joists where seams will butt.
2.   Place additional fasteners on the adjacent board 
over the joist and framing boards where the seam 
will be.
3. Put the fi rst board of the seam in place and 
secure with fastener.
4. Following proper gapping for abutting boards (see 
page 32), place second board in proper location 
and secure with fastener.
5.   Place second set of fasteners on each side of butt 
seam for each board.
