We just bought a house with the orginal plaster walls built in 1901. When we moved in, there was a textured wall covering that had been painted with 5 layers of wall paper under it! We scraped and steamed and now have bare walls that have a few baseball sized holes, a few 4 foot cracks and some weal spots that move when slight pressure is applied. We thought about using beadboard to cover it up, but there are four doors and a bay window that would be difficult to work around b/c we are diyers. Then we thought about hanging dry wall, but the thinest we can find is 3/8" and this would mean that we would have to remove the orginal base boards and crown molding which we don't want to to. We are thinking of patching the holes and using a textured plaster which we could paint. Is this method the best? I was not so sure that textured plaster would maintain the acrhitectual integrity of the home. If it is ok for hte period of the home and it would be the best fix, what materials should we use and how difficult would this project be for two people with not much experience? Thanks for your help!
