Hi! We bought a 107 year old farm house about a year and a half ago. When my husband painted the walls in our downstairs hall (which is the majority of the house)they began to chip and peel within a few months. Since then, he has peeled off the paint and sanded down the areas and repainted them only to have them peel again and again. Is this because of the plaster? The walls are cracked pretty badly all over the house but it's the peeling thats driving us crazy. I'm thinking the best solution is to put up wall paper. Any suggestions? Thanks!
