What do you use to permanently glue fist sized rocks together?

Answered
I am making Trolls (Like in the movie Frozen) with my grandchildren by gluing rocks together to form the head and body. We then add small rock eyes, noses and seashell ears. We tried hot glue, but it doesn't take much pressure to make them come apart. Is there another kind of glue that will hold well, but dry fairly quickly? We also embellished with reindeer moss. With the first rain it bled all over the rocks and after a few days it was badly faded. Is there anything that could be sprayed on the moss to make it hold up longer?

  • What about construction adhesive? What a cute idea!

      @Amanda @ Our Storied Home I'm not sure what you mean by construction adhesive. Liquid nails?

    Maybe that E6000 glue from Walmart?

      @Heidi Geores I had never heard of this glue before. I'll have to check it out.

    Try Gorilla glue...or check at the hardware store - they may be able to recommend something since this will be outside.

    I would try cement patch that comes in a tube like calking.

      @Diane Thank you. Sounds like a good idea.

    If the E6000, which is everywhere, doesn't hold the weight I would try the adhesive they use to hold the cap on block walls.

    Try outdoor silicone caulking used in construction or repairs - everyone swears by E6000 but I used it for my outdoor clay pot people and it didn't last and besides, it doesn't dry quickly.

      @Gail@Purple Hues and Me Thanks for sharing your comments about E6000. Glad to find out it didn't last outdoors before I went that route.

    Get some epoxy putty Has two parts you mix together. Sets in five minutes

    Thank you for all the suggestions. I tried liquid nails. It does a fairly good job but you have to wait 24 hours for it to dry. Not something you can do with impatient children! LOL I'll be trying some of these other ideas.

    If you ask an astromical physicist when enough rocks are next to each other they magically stick together.
