What epoxy/glue should I use?

[Amedeo]

What epoxy/glue should I use for an OUTDOOR granite slab which has a hairline crack?

Thank you

I would use a penetrating epoxy to bond the crack and then you can use a knife grade to seam the crack. Just make sure you color it to match the rest of the stone.
Let me know if you need links.

Glad to be of service,

we use what they call "A B" glue. this is the only thing we will use outdoors, everything else deteriorates. it gets over 120 degrees on a regular basis here in the summer, im sure that accelerates it quite a bit. depending on where you are you need to find a glue that is specifically suited for outside, otherwise i promise youl be doing it all over again. i dont know where we get the glue or who makes it.
