Self-adhesive sealing strips for doors and windows:

1. Before installation, clean the sticking position first to ensure that the sealing strip is closer to the notch.

2. Tear off the adhesive tape of the sealing strip, and affix it to the position.

3. When installing the two ends of the interface, shrink the middle of the two ends, leaving about 2 to 3 cm, and cut off the sealing strip.

4. After the sealing strip is attached, gently press it tightly with your hands.
