Installing Assured Composite® Corner Trim

Composite Corner Trim Finishes The Decking

Fixing Composite Corner Trim To Decking

Carefully plan the area checking all measurements.

​Measure and cut composite corner trim where required.

Fix the composite corner trim by covering the decking board edge. Pre-drill holes and fix into place by screwing directly through the composite corner trim and into the decking board and riser. Start at 80mm approx and then at every 300mm approx intervals.

​Leave a 2mm expansion gap when joining composite corner trim.
