I doubt that you could paint it and make it look good. But then, it must be almost 50 years old so you have gotten your usage out of it. Take it out and replace with a good ceramic installation.: I would like to know if one can paint plastic bathroom wall tile? If so, what kind of paint, what are the results, etc. I want to do this in one of my bathrooms only if it looks very professional when Im done. Otherwise, I plan to pull off the plastic tile and replace it with ceramic. Can anyone tell me if they have had success with this? Thanks
