I built my wife an LSU welcome
Sign for our front door. When getting paint colors, I was so engrossed in getting the right colors that I never even thought about getting an outdoor paint. So
Now that I have spent hours painting and stenciling, it dawned on me that this probably won’t last a week in the sun. So I was wondering what would be the best clear to put on that paint to protect it from UV and water damage. Is there even such a finish that will do that? Any help would be appreciated.

Marine Varnish is generally the go to for extra UV blockers. Think boat building websites for more details. Epifanes is the brand that comes to mind first for woodworkers. I’ve used it on exotics like purple heart and paduak to keep them from browning. However, everything will fade eventually. UV blockers just slow down the process.

The only “good” outdoor UV blockers are pigments, clears work for a while, but need upkeep.

I’ll second the Epifanes, I used it on some southwestern clay “wall pottery” that is painted and it has held up for 5 years (albeit on a north facing wall 8^)

The Epifanes needs to be thinned as canned and smells horrible, but it is the best I’ve tried.

Thank y’all for the input. I will check that product out. I know nothing is indestructible. I work in the cabinet business and have to explain that to customers constantly. But most the work I do is interior so I don’t know much about outdoor finishes. Most likely will be making her a new one next year or possibly this year lol. I will get the outdoor finishes next time. Thanks again fellas

can you share a photo of your sign? sounds like an interesting project.

my vote would be for Pettit Marine Spar.
it will take a minimum of 5 coats to give a good UV protection.
depending how much you value your sign, 10 thin coats would be advisable.
then every two years, clean, scuff and add another coat.
the back side of the sign should receive several coats of a good latex paint.
there is NO one-coat-and-forget-it product on the market today.
stay far, far away from any MinWax products !!
Epifanes is a great product – but will give an amber (honey) tint when you
apply several coats.
