Insert panel into the Edge J-Trim if applicable. If using the Edge J-Trim, attach the trim up to the ceiling before installing the ceiling panels. The trim can be bonded to the wall using PL Premium adhesive by applying a 1/8 inch bead to the back of the trim and pressing firmly into the drywall. Staples can be used to tack trim in place until adhesive is cured (24 – 48 hours). Alternatively, drywall screws can also be used to attach trim to wall. Do not over-tighten screws.
