So right now, a quarter of my garage (drywall)ceiling is sagging, the edges of this square are tight to their joists and it sags evenly to the center (where someone installed a fluorescent fixture with toggle bolts / not to a stud/joist..)I tried to fix it by taking drywall screws and starting at the edges (where the drywall actually touches the studs) and working towards the sagging center, but as soon as I got away from where the drywall was touching the joists - when I began relying on the screws to raise the drywall to the joists/studs - the screws simply went through the drywall, the drywall didn't even try to raise the screws went right through (regular #6 1 1/4" drywall screws)My new plan is to do that same approach, only using washers with the screws so they actually 'bite' the drywall and lift it when I'm screwing them in, but my concern is that, with it bowing so much (~3-6" in the center of a ~15'x10' corner of the garage) and with the screws going through it w/o it even moving up a little, that even washers are going to go right through the drywall (am planning to get big ~1-2" washers but still worried it's not going to 'bend' the ceiling back up so that all joists are in contact with drywall..)Is my approach doomed? Only other idea I can think of is getting 1x4's, like 5'+ sections, and screwing them to the ceiling perpendicular to the joists, kind of 'sandwiching' the drywall between my 1x4's and the joists (no idea how I'd actually get the drywall in-place to do this, fear that pushing it up will crack it)Thanks for any tips/help on this, landlord is going to replace but not for over a month, reallllly want to secure this myself I don't care how ugly it is I just want it to stay up!! via /r/DIY http://ift.tt/2u11kpq
