I painted sidewalks, then streets, and planted more quick growing grass. I need to do some touch ups. I have the same problem I had before with this flat black paint. It’s shiny. The last time it was over plywood. The last time the lady in the paint store suggested using a large eraser to buff it. That worked. I thought maybe going over homasote might be different; but it wasn’t. I also have to cover the copper tape and repaint it.
