Instruction:
- For small and lightweight letters or signs:
No need to cut the nozzle. Simply apply the adhesive in small dots, then press the item firmly into place. - For larger or heavier letters:
- Cut the nozzle and apply the adhesive in strips, about 1/2 inch from the edge, spaced 6 inches apart.
- Press the letter firmly onto the surface.
- Then, gently pull one end of the letter away at a 30–40° angle, hold for 3–5 seconds, and press it back down.
- Repeat this motion 3–5 times to ensure strong bonding.
- For very large or heavy letters:
- Decrease the spacing between adhesive strips.
- Repeat the pulling and pressing motion more times to enhance adhesion.
Precautions:
- Ensure flat surfaces – Both bonding surfaces must be flat and have enough contact area. Uneven or very narrow surfaces may not hold the adhesive well and could lead to failure.
- Use carefully on clear materials – When applying to clear acrylic, glass, or similar materials, be cautious as the adhesive may leave visible marks.
- Avoid on sensitive materials – This adhesive may cause slight corrosion. Do not use on foam boards, or UV reverse-printed acrylics.
- Test before use – Because advertising materials vary widely and frequently change, always do a compatibility test before full application.
