A hammer tacker can be used for many purposes, such as: installing roofing paper, carpet backing or even installing insulation. You use a hammer tacker much in the same way as you would a regular hammer; however, there are a couple of differences and things you should know in order to use the tool effectively.

What's the difference between a staple gun and a tacker?

Squeeze or Whack? The chief difference between a staple gun and a hammer tacker is right there in the name: one works with a trigger, while the other work like a hammer. A staple gun comes with a handle that you squeeze to trigger the spring mechanism that fires the fastener into whatever you're securing in place.

What can I use instead of staple gun?

No staple gun needed in my experience. Just some double sided tape, glue or even without it will easily hold.
