Installation Information
- Make sure both the panels and the surface to which the panels are being applied are free of dust and dirt. If adhering to a metal surface, use a degreaser.
- Apply a line of adhesive around the perimeter of the panel approximately 1" from the edge.
- Apply a line of adhesive from opposite corners through the center of the panel, creating an "X".
- Press panel into place and hold for 5 seconds. Then pull panel away to allow adhesive to become tacky. Last, press the panel back into position and hold again for 5 seconds.
- Wear clean cotton/canvas gloves for installation.
- Use a sharp razor or fixed-blade knife and a metal straigh edge to cut panels. For best results, cut panels on flat side.
- Overhead installations may require additional adhesive and mechanical support to ensure a strong enough bond.
