When sealing a mosaic piece, what should I seal it with?

I recently made some mosaic house numbers. They are going to be used on the south side and the sun really hits it. I want to make sure I’m not going to lose any of the little pieces.
Suggested Project Book
you need something w/ UV protection -- KRYLON makes a UV resistant clear spray sealer ...
marine grade clear sealer
If you used silicone as your adhesive, you shouldn't need a sealant. But you could use a spray on sealer as previously suggested, or pour a resin sealer over it.
Use a waterproof acrylic sealant
