Polyurethane with UV protection

Posted by jenel (My Page) on

My outdoor shower mosaic contains some stone beads that have a colored coating. The bead store suggested that I protect them with polyurethane that has UV protection because otherwise, they'll fade. Do any of you know a name brand I can search for? Also, the mosaic contains mostly stained glass. Will the polyurethane stay on the glass, or will it peel off and look ugly? I'm thinking the best route would be to individually paint the polyurethane onto each bead. I'd rather do it right than do it fast. I'm not worried about inconvenience. I will take as much time as I need to do the job right.

I wouldnt cover the stained glass with it as it doesnt need protection and it ptobly would peel off IMO-I dont know a brand of poly with UV protection, sorry!

RE: Polyurethane with UV protection

Thanks, wacky! I've come to the same conclusion about the glass. It's better not to take the chance that it would peel and look horrible. I think the right answer is to paint whatever I use onto the stone beads.

RE: Polyurethane with UV protection

Polyurethane UV protection is only a short term protection - basically yacht varnish will last a few years then start flaking and need sanding down and replacing. Stone seal might be better as it would just fade away over time, rather than flake and could then be rejuvenated with another coat, but I think you'd do better to just leave it be

RE: Polyurethane with UV protection

I ended up getting a crafter's polyurethane from Hobby Lobby because everything I found at Home Depot was for wood. (That's probably the yacht polyurethane you mentioned, african.) It doesn't say anything about UV protection, but I gave up on that idea. All I can do is the best I can do. I'm going to brush it on the stain flowers before I grout. The only thing the bead store was worried about was fading, and even if the stone flowers fade to white, I think it will still look good.
