What is the best way to seal/protect my mosaic glass stepping stones?

I have already used an outdoor grout sealer, but I am wondering if there is something else to use to strengthen it more.
This isn't a great photo, but you get the idea. It will be placed outside as a divider between grass and gravel.
Where do you get that marine poliyurethane?
Those are amazing!! Ive been picking up stones,rocks,pebbles,shells and i may part with some seagrass,(doubt it). Im thinking its a fall or winter project asnita time consuming.
That's beautiful, Kathleen. To seal something like this I would look for an oil-based, non-tinted masonry waterproofer. It lasts a really long time outdoors and doesn't require resealing in a few years. Apply as you would any other sealer.
