How To Use
How to Use Alien Edge
- Clean the Surface
Wipe the area with a dry cloth or rubbing alcohol to remove dust, dirt, and oils. Let it dry completely. - Measure the Gap
Hold Alien Edge along the window or door frame to estimate the length you need. - Cut to Size
Use scissors to cut the strip to the exact length you want. - Peel the Backing
Slowly remove the adhesive liner to expose the sticky side. - Stick & Press
Apply Alien Edge firmly along the edge or gap, pressing down the entire length to secure a tight seal. - Smooth It Out
Run your hand or a flat object along the strip to remove air bubbles and ensure full adhesion. - Let It Set
For best results, allow the adhesive to set for a few hours before stressing or opening the window/door.
