I live in a 1940's home. The bathroom has the original plastic tiles on the wall. While they are actually still in good shape, the color is a horrid robin's egg blue... Some of them appear discolored or faded. I really can't afford to have my bathroom remodeled for a few more years, but would like to do a little spruce up in the meantime. Has anyone painted plastic tile before? I'm not sure if one would use a latex or oil based paint for best result... Or another type of paint altogether. Any advice would be helpful. Thanks!
