Expert Verdict — Reviewed by the SuperArbor Pro Desk
Cortex is the go-to choice for perimeter boards, stair treads and picture-frame borders where clip systems can't reach. Keep plugs oriented consistently with grain direction for the best camouflage, and don't overdrive the screws or the plug won't seat flush. Order one kit per 100 linear feet plus a spare plug pack for cutouts and misfires.
Wear eye protection when driving fasteners, and follow the manufacturer's installation instructions for screw depth and joist spacing.
