Plaster repair in a home built in 1905-HELP!
Well everyone, after noticing the paint peeling away from the windows, like a peeling sunburn I starting picking away. 24 hours later, I found that a liner paper had been placed over the original plaster walls (1905 home)and painted by the previous owner. What is left are gray plaster walls that leave a residue on my hands when wiped. What is this? What is the next step now that I created a monster!
