We have removed layers upon layers of wallpaper from 4 rooms in our 1860's Maine farmhouse. Most of the walls are horsehair plaster and a few are old drywall. We want to paint them all so that they are uniform.
My first question is for the plaster walls-- There are a few areas that have chipped off/cracked and there are some large holes with the wood backing showing through (all in good condition). I know how to patch everything but what specifically should I be buying to fill holes, patch, skim, etc? Do I need a bonding agent? Are there brands or types that you would recommend and is it likely to be found at Home Depot or a local hardware store?
Second question is-- Paint. What type of paint should I get, can I just use a Kilz primer and latex paint or is there a special kind to get? I'd like it to be the same for the drywall walls so that they match.
Has anyone heard of an insulating paint to use for plaster walls? Would you recommend it?
