I did an area above a garage using a mud (drywall) mixer on a drill and bent wire to fluff it up... for the few bales it worked and i leaf raked it level... on flat ceilings with room to work it would be ok...

I did an area above a garage using a mud (drywall) mixer on a drill and bent wire to fluff it up. For the few bales that I used, it worked well. I used a leaf rake to level it out. On flat ceilings with room to work it would be OK.
