Is epoxy resin a good medium to use for outdoor projects?

I would like to utilize the sea glass I have collected in the area on and around my porch. I love the idea of resin instead of grout for mosaic projects. However, I don't have any experience with it and am wondering if it will withstand rain, freezing, etc.

    Use marine epoxy it will last longer. You can watch YouTube videos to learn how to do it

    For wood epoxy and exterior varnish. The epoxy forms an impenetrable moisture barrier that prevents seasonal swelling and shrinking of the wood. This dimensional stability in turn gives longer life to the exterior varnish because it no longer has to stretch and shrink with the wood The exterior varnish returns the favor by providing UV protection, without which the epoxy would rapidly deteriorate.

    I would imagine it would as grout holds up even in Maine winter weather. It would be nice though if sea glass was used in a non-invasive way, I mean where the glass itself isn't permanently attached to another material. What about using hot glue?
