Step 5: Glue the staples
Get something that will dry overnight. The most important thing is that it comes with a long tip applicator that will fit under a staple stick.
Lay the mirror over a bucket or trash can, this way you can rotate it as you go.
Put the tip of the appicator as far as it can go underneath one staple stick and deliver the glue.
You will know is enough when you see the stick rise a little bit, then it comes back down.
skip the up side down stick and go to the next "tunnel". This will glue both upside down and right side up staples.
Once you go all around, leave it dry overnight.
This is your last chance to make minor adjustments to the staples.
