Installation Information
Cortex for Fascia can be installed using a 18V or greater cordless drill for all parts of this installation. An impact driver is not recommended.
For 1x8 fascia, install a vertical row of 2 fasteners every 18". Use 3 fasteners for 1x12 fascia. Install the first and last row 1" from board ends, tack the fascia board into place using a few Cortex Fascia screws and leave the heads slightly raised.
With fascia in place, drill the recommended fastening pattern using the Cortex Counterbore Tool.
Install screws into each prepared hole using the Cortex Fascia Setting Tool. Drive in one continuous motion until fastener is seated, keeping the fastener perpendicular to fascia for best finished look. Install Cortex Fascia Plugs over each screw head.
First, align the grain to match fascia and set into position by hand. Using a clean, smooth faced hammer, gently tap plug to flush. Remove the tacking screws, counterbore the resulting hole, fasten and install plugs to finish the job.
