Recently bought a fixer-upper and have some questions for all you helpfuls out there. 1)Removing wallpaper solution of vinegar/water--what is the ratio? 2)Going to put up a new border, it is pre-pasted, it seems everyone says to add your own paste for whole wall but what about a 4" border? 3)Acoustic ceiling tile above shower surround is sagging and has recessed light-- can I just staple the tiles back up and harness the fixture from the ceiling or is there a better way? 4)The house has an oil/water baseboard heating system, but there is also a separate Energy King wood burning furnace that has been disconnected and I am interested in finding out if it can be reconnected and if it would be in working order once connected. There are no id markings for model from Energy King, but have info on the gauges from their mfr if that would be helpful. It stands about 4 1/2' and would have it's own chimney. Any responses would be appreciated to one or all situations. Thanks in advance to any help.
