1/4 inch thick panel with some flex to accommodate slightly bowed ceiling
 
Is there such a product as a thin 2x8 or 4x8 paintable panel that could be screwed through a plaster ceiling into the joists, something with a little bit of flex to accommodate a slight bowing of the ceiling?

A 4 x 8 sheet of 1/8" or 1/4" MDF. One side is usually finished smooth. Are you using this to cover the old plaster?

Thanks for the info.

Yes. The original owners applied paint with a sponge over crazed plaster to give a quasi stucco effect and mask the imperfections. Now the paint is peeling badly in some places and sticking like superglue in others, so I'd end up with vast stretches of bare plaster and vast stretches of roughly textured paint. Considering my alternatives.

How much does it "bow"? I think most people here would suggest 1/4" sheet rock for covering a whole wall, as long as the bow isn't too much.

The bow is about 1/2 inch.

about 1/2" in what distance?

The lowest point of a 6 ft span is about 1/2 inch low at mid-span. The room is 6' x 7'.

A layer of 1/4" drywall glued and screwed would be good. Around here we can get a 1/4" thick ceiling panelling that is 4' by 4' which is scored to look like 1' tiles. Looks cheap to me but may meet your needs.

slap some mud on it.
Not sure why, some seem you need to cover it with drywall and then put mud on it.
Why not just mud in the first place to smooth it out and re do the texture?
Really is not that hard or takes that long.

There are a couple of reasons why I didn't just mud the ceiling.

1. I'm pretty good with a trowel on walls, but not on ceilings. I get a crick in my neck and then I lose all patience and get sloppy.

2. I was concerned about the added weight pulling down on the plaster, since I wasn't sure why it was sagging in the first place. Could be the joists are sagging, or it could be the nails holding the lath to the joists have rusted and are losing their grip. Screwing new drywall though the plaster into the joists seemed a sturdier solution.

Thanks. I'd like to find it without the faux tile look, but haven't seen it around here.
