Painting - Flaking Bathroom Ceiling: Repainting Of ?

Hello:

The ceiling in our bathroom (probably just the typical, painted drywall) and
on our shower stall ceiling which is not tiled have begun to flake badly.

We do have an exhaust fan in the bathroom, but obviously it's not doing an
adequate job.

Should we just scrape and re-paint ? Re-plaster the surface and then
re-paint ?

With what ? Brand ?

Any "special" surface coatings or treatments first ? Or,... ?

Any suggestions or hints on how to handle this would be most appreciated.

Much thanks; appreciate it,
Bob

You'll want to scrape and sand any loose stuff first
If you can feather sand the edges of the repair areas, then do so
If they will need a skim coat of joint compound to smooth them out, then do so

As this is a problem area, if you need to skim coat, spot prime with Zinsser's 1-2-3 first, skim, dry, sand, then spot prime again
If the area is very small (just little touch-ups) you could possibly skip the primer
If the repair goes down to drywall at any point, you should prime before skimming

I'd recommend Zinsser's Perma-White for the paint
It is extremely mold and mildew resistant, very adherent, and will not require a primer (except for the repair area as noted above)

The only thing is Z's P-W can only be tinted light or pastel colors
If you need a darker color I'd recommend Moore's K&B from Ben Moore
I would prime the whole area rather than spot prime if that were the case

I agree with slickshift. If you choose to use a different brand make sure it is latex enamel.
Is it possible you aren't letting the exhaust fan run long enough?
