Spray paint, rustoleum, is great for redoing metal chairs, tables for outside. You can pick a color and presto a new look. I have painted old folding chairs to use outside, metal table found at yard sale, plant stands. Painted baskets to put the plants in for outdoors. Also, a cheap wood table will last out side for a few years. Doesnt have to be a specail picnic table. maybe find one at yard sale or the "dump/recycle place". Ask on freecycle. You can find plants there too. They also have special paint now for the plastic lawn chairs. I have seen them as cheap at a dollar at sales. Dirt comes off with magic eraser or a lot of elbow grease. Just some ideas that I have used over the years. Babs
