How do you get decals off walls?

Decals come standard with adhesive and this is designed to stick to your surface. Different quality decals have different quality adhesives. Some are designed to be long lasting, others are repositionable and other for high traffic areas like laptops.

The 3M vinyl decals are made with mini dots of glue and once you are happy with your positioning, you push the front of the decal and this pops the mini dots of glue and forms a strong bond with the surface, very clever.
