I painted the smallest one first using exterior waterbased enamel porch paint. I bought 3 different shades of green think 2 would have been fine for this project. So here is the 1st finished leaf and I am going to do two of the 4 ft'ers next. Ric is setting up in the barn to finish grinding the rough edges on a few that didn't get finished last year. He said it was so much easier working on the green concrete than it is now.
1st pic is base color, 2nd pic is finished project it isn't quite as light and you can see more of the shading than shows in this picture. I painted part of the underside leaving a spot in the middle for the concrete to breath. Not sure that was the right thing to do but seems to me I read somewhere that you don't want to seal it completely I know that my ceramics that were put out side were not glazed on the inside. Next one to paint, takes up half the table top.
