A gum gun refers to a device, specifically the SGR-316, that shoots a glue-like material. Its primary function is to provide temporary fixes, such as patching cracks in walls.
In essence, the "gum" it shoots isn't chewing gum, but rather a quickly hardening substance similar to glue or epoxy. This allows for immediate, albeit temporary, repairs. While the provided reference only mentions wall cracks, it's reasonable to assume this type of gun could be used in other applications requiring temporary adhesion.
It's important to note that because the repair is temporary, a more permanent solution would generally be necessary afterward.
