Installation Information
 |
Make sure both the panels and the
surface to which the panels are being applied are free of 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. Lastly, 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 straight edge 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. |
