We recommend thoroughly degreasing your sign blank with the Stykra EXT cleaner and priming the panel with Stykra EXT primer which will ensure your bond is as strong as possible. Please see our instructional video below:
Once your channel has been bonded to your sign blank for 72 Hrs, the adhesive will be at 95% strength and ready to install on your post. Just slide the channel clamps into the aluminium rail and use your universal screw banding to fix it to the post.
