Someday I will share this entire garden art backyard...but for now, I wanted to tell you that I used exterior paints on this project and that was 8 years ago! The clients had me refresh the colors after 5 years. (the HOT Arizona sun was beating down and it faded a little....) The faded look was actually really cool looking...but it was more work for me.
What my point is
tells us that sometimes a sealer isn't needed if you use exterior paint. On my curb art projects, I don't seal. So I'm wondering if you can paint the birdbaths and not use sealer.
