Adhesive for gifted?

How to use tiny and English. I claim to speak English and know tinker there but IMPOSSIBLE!
I searched clear instructions on the Loctite website: there is none.
I looked for a tutorial on the web: nothing.
I called 2 DIY stores: they do not know this.

So I did as I could: it seemed to hold (after 1/4 hour, as shown). I put the mirror and everything fell 5.60 in the trash and lost 2 hours.
Looking back, I think the wait of 15 minutes is too short: count one night, rather.

I highly recommend, I finished to the garage (15).
