I need real help! We bought a 75 yr home. great condition. The problem is, we had our bathroom remodeled and now our kitchen ceiling (which the entire interior is horsehair plaster) is cracking really bad! we did some compasions and between drywall and handing ceilings. And we kinda want to go with the hanging ceiling. using 12 inche tiles. Our questions are: do we need to remove the old ceiling and then hang the ceiling or can we use the tiles we found at home depot that are used by stapling through the plaster into the studs in our ceilings? Can anyone really help me? i plan on doing this myself!
