I just bought an older house that was built in the 50's. The basement had been converted to an apartment, previously. Most of the walls are wood or some kind of wood like material-not sure really. I thought it ugly and decided to paint. Most of the paneling did quite well but on other walls, the paneling was different looking. (not wood) I have asked others in diy stores and was told that if you sand the surface and prime the walls with stain resistant primer such as Kilz, then you can paint. When tested on a "test" piece, it worked fair, except very easy to scrape off--is this the best that it gets? or is there another alternative?
