How can I protect my mosaic stepping stones from wear and sun damage

My mosaic stepping stones are not all the same level. What im trying to say is I used sea glass and tile on them so the sea glass is higher than the tile so I need something thick to cover them that will help level it. I used polyurethane last time and the poly on the sea glass wore down and the sun turned the polyurethane yellow.
