replace12" ceiling tile with drywall on dropped


Unless I am not seeing something in the photos, those too long to start 2x4s are just attached with a couple framing nails on the ends? No hangers? You really don't want to hang a drywall ceiling from them. One dangerous ceiling you have in mind!

I would take the suggestion to reframe with 2x6. Or shift thinking to some other lightweight ceiling tile or suspended ceiling. Some of them don't look so bad if you paint them.

The length of screws you are thinking will not help this situation. The weight of the drywall will just be too heavy for this framing as shown.

I always guess. It is easier and less stressful than thinking. And thinking is the enemy of perfection.

But come on, don't be cynical. Good 16p steel nails are really, really strong! And I bet there are two in each end of those 2x4s in the pic? Why not give them a chance.

Found this site that offers small sized hard hats for women and children. Just in case.

And what woman wouldn't love a properly fitting hard hat for her and the kids and maybe a countertop appliance for Christsmas?

I would go with Dave's suggestion of tie wires mid span. Commercial drywall ceilings are hung from channels suspended by tie wires all the time, and the sheets are screwed to stuff a lot lighter than your 2x4s.

You would be comfortable having your family living under it with just tie wires and 16p nails holding the ends?

Tie wire when done correctly which is what I mentioned will hold up plenty of weight. The weight of a typical commercial retail space is done this way and is far greater in weight than an residential ceiling. The ties are held in place with an eye bolt lag anchor. No nails are involved.

I came over from Drywall talk to poke my head in. Just my .02, but your idea is pretty good, same thing i'd suggest: Using 2x4 or 6 stiff back above the 2x4's to stiffen it up, and tie it up to old ceiling somehow. Maybe knock a hole in the old ceiling and face nail a 2x that also cacthes the stiff back and new ceiling.

Leave the old strapping or grid and go over it when new 14's cut to 13' or just use 8's, you'll have butts, but 13' of board may too hard to handle. We usually nail perimeters and screw the fields 12" on center. Good luck, let us know how it turns out!

PS: #
3" screws wouldn't be necessary, the standard 1 1/4" coarse thread are okay if your grid is well secured, if not 2" would be plenty, would still penetrate by 3/4", code is 5/8". And 3" screws will have a much bigger bugle and be harder to coat.

And a typical homeowner or DIYer could accomplish this how crawling around a 24OC 2x4 ceiling hung in place with, hopefully two nails holding the ends in place?

Use the nice 2x4s to build a drop dead gorgeous house for the dog or a playhouse for any little girls in the family.

Reframe it and do it right. It is a residence, not a commercial structure. Hanging things like a structured ceiling from wire here in a residence will not match code or pass inspection. And all the wire in the World will not get 24OC past inspection for a drywalled ceiling.

Commercial standards are higher than residential. So I cannot see why you think this would not pass inspection. Same with 24"OC.... still meets code. You just need to use 5/8" drywall if the studs are on 24" centers.

So tell the homeowner DIYer what tools he will need to climb around in 3' of clearance to anchor this ceiling. And what fasteners? Wire gauge? How many inches on center? You are not suggesting he just screw something in mid span are you?

Cost.

Come on guys, would he not be better just demolishing the current ceiling, biting the bullet and framing with 2x6? Attached with real ceiling joist hangers?

What could he possibly be saving with your tie wire approach? And think of what he is risking if he does not do it right.

And I am sorry and bless them, but I could never get a long span 2x4 ceiling, nailed in with only 16p steel at the ends, and even supported with tie wire past an inspector here for a residence with 5/8 drywall hanging on it.

It appears you may have 12"x12" "staple up" tile installed on 1"x4"s on 12" centers, which were used as "strapping". The drywall is quite a bit heavier than the acoustical tiles and would likely sag with the 2"x4"s on 24" centers. You could possibly add hanger wires for support as long as they are anchored solidly into the framing members of the original ceiling. Some type of framing (a "cat walk") down the center out of 2"x6" would help. Make sure the 1"x's are also fastened securely to the 2"x4"s. I don't think you need to tear out the existing framing unless there's a problem with it being uneven or the like. Then it might be easier to start over than straighten it out....

In order to get the 2x above the drop ceiling, he may have to cut the strapping back at one joist bay. Still less work that tearing it all out.

Yeah the 2x6 in the middle & use a wire to the old framing
As stated the key is making sure that support wire is supported directly by the framing above the old ceiling
They have lag bolt with an eye at the end
Something like this but a threaded lag

If the existing framing is level no need to tear it out, it can be quite a challenge to put up new framing 9' over head

If you look in the area where the suspended ceiling material is, they have a lag screw that is flattened on the end with a hole to thread your hanger wire through. There's even a special driver to chuck into your drill to install them. I've seen them at both HD & Lowes.....
