Hello, DIY novice here! Updating our 1952 ranch, and want to remove all the base molding. Not worried about damaging the molding, we won't be reusing it, but trying not to damage the plaster walls. Molding is attached with nails, no adhesive. Tried easing it a bit at a time with a lever and a block against the wall to distribute the weight, but plaster is still crumbling anyway. Any suggestions for other methods of removing the molding? We will be replacing it with new and slightly larger molding (so I suppose some damage will be covered, but we'd still like to keep plaster as much in tact as possible). Thanks for your help!
