1. Before applying the tape, ensure that the surface is clean and dry. Use a clean cloth with a small amount of isopropyl alcohol (IPA) to wipe the surface, removing dust and fingerprints. Avoid using household cleaners as they may contain oily substances. Let the surface air dry for a few minutes before applying the tape. For surfaces with heavy contamination (grease, oil), clean with a stronger solvent before wiping with IPA.

2. Apply one side of the tape to the object to be adhered, use a squeegee, roller, or fingers to evenly apply pressure to the surface, eliminating air bubbles and ensuring a smooth application.

3. Peel off the release liner of the tape and adhere it to another surface. Apply pressure evenly. Note: When adhering two hard surfaces, it may be challenging to eliminate air bubbles due to surface irregularities. Increase pressure to 15-50 PSI. Adhering to a soft surface is easier with pressure of 5-15 PSI.

5. Adhesion strength reaches optimal levels 72 hours after application. It is recommended to test the adhesion effect after this period.
