In the face of the problem that the hole-free hook cannot stick, it is first necessary to clarify the reason, which may be a wall problem, a hook quality problem or improper operation, etc. For different reasons, corresponding solutions can be taken. Here are some specific solutions:

1. Clean the wall: Make sure the wall is clean, dry and smooth. If there is dust, oil or other impurities on the wall, it will affect the viscosity of the hook. You can use a semi-wet cloth to clean the wall to ensure that the wall is clean.

2. Select the appropriate paste position: When pasting the punch-free hook, you need to select the appropriate paste position. Avoid sticking on soft walls or uneven places, so as to ensure that the hook can be evenly stressed and improve viscosity.

3. Use auxiliary tools: You can use professional adhesives or double-sided tape and other auxiliary tools to increase the viscosity. Ensure that the adhesive is evenly applied to the attachment surface of the hook and follow the instructions.

4. Check the quality of the hook: confirm that the quality of the purchased hole-free hook is reliable. If the hook is of poor quality, it may result in insufficient stickiness. When buying, choose reputable brands and merchants to ensure product quality.

5. Appropriate increase in pressure: After the hook is pasted, appropriate increase in pressure can help the adhesive to better adhere to the wall. Press the hook by hand for a while to ensure that the adhesive is fully cured.

6. Seek professional help: If the above methods can not solve the problem, it is recommended to seek professional help. Professionals can provide more effective solutions according to the actual situation.

7. Pay attention to the use of precautions: Although the hole-free hook is convenient, it is not suitable for all occasions. When using, you need to follow the instructions of the product manual to avoid overloading or using it in inappropriate situations.

In short, in the face of the problem that the hole-free hook cannot stick, we must first find the reason, and then take the corresponding solution. This problem can usually be solved by cleaning the wall, selecting the appropriate paste position, using auxiliary tools, checking the quality of the hook, and appropriately increasing the pressure. If the problem remains unresolved, it is recommended to seek the help of a professional. I hope the above suggestions can help you solve the problem that the hole-free hook cannot stick.
