Bullnose Edging Installation

How to install Hyperion® Frontier bullnose boards

Bullnose Edging Installation

For use with Hyperion® Frontier composite decking.
Bullnose boards are solid boards with a rounded edge. This can frame a decking area or work as a finishing touch needing a rounded edge board. The bullnose board has increased strength due to the solid internal structure and can be used as a step.
  • Ensure to keep a 6mm expansion gap between edge board butt joints.
  • The bullnose must be installed before laying down the decking.
There are two methods for installing bullnose boards:

Parallel bullnose board installation

Step 1

Where fixing the bullnose boards around a corner, mitre the ends at 45┬░ angles.

Step 2

Secure starter fasteners onto the outer joist at 400mm intervals.

Step 3

Line up the bullnose board and lay the underside groove directly on top of the starter fasteners.

Step 4

Push the board forward to lock the board.

Step 5

Secure the remaining side of the bullnose board with hidden fasteners.

Perpendicular bullnose board installation

Step 1

A full joist width must be used under each deck board end, thus where the bullnose board runs perpendicular to the main deck, you must have a double joist structure.

Step 2

Secure starter fasteners onto the outer joist at 400mm intervals.

Step 3

With the bullnose board in place, screw through the hidden fastener groove at a 45┬║ angle, securing it to the joist.
  • Pre-drill pilot holes in the deck boards 2mm wider than the screw shank.
  • Do not over drive screws into the deck boards to avoid the material splitting.
