Stepping stone sealant?

[jeaniebueller]

We painted concrete stepping stones with acrylic paint and I need to put some type of sealant on them to protect them from the elements. Google is being completely unhelpful and giving me directions on how to use a sealant....lol. What type of product am I looking for here? My DS also painted some really cool rocks and I hope that I could use it on them as well.

Id probably use that or something like it. A spray on waterproof, weatherproof sealant. Bonus points if it also has uv protection.
