To use make up plastic, follow these steps:

1. Preparations: Before bonding, remove the water, oil, rust and paint of the joint surface to ensure that the joint surface is clean and consistent. If the vamp is too smooth, you can use smooth file to gently polish the cracked position, and then clean up the dust.135.

2. Gluing: when using, you only need to squeeze out a small amount of glue on the joint side, press the other side, and stop slightly to locate the initial consolidation. Or double-sided glue, evenly coated in every corner of the crack, do not glue immediately. Do not glue too much, as thin as possible123.

3. Drying: After the glue is applied, it cannot be bonded immediately. Open the crack and wait for 5-10 minutes to allow the glue to cure naturally.37.

4. Heating and pressing: After the glue is natural drying, heat it with a hair dryer for about 30 seconds, and then press the crack hard for more than 20 seconds. The stronger and longer the strength, the better the bonding effect.37.

5. Fixed and static: use beef tendon to fix the adhesive place and stand for more than 24 hours to ensure that the glue is completely cured, and then you can wear shoes.37.
