I had a stucco like substance on my bathroom ceiling that was peeling and falling off. I scraped it all off and found a layer of pink paint beneath the stucco that also was peeling in many spots. Underneat the paint is plaster that has some spots. I have an exhaust ceiling fan in the bathroom but don't think it works terribly well. I am considering scraping the remaining paint off then filling in uneven spots and corners with spackling compound then painting over the whole thing again but I am concerned that the spackle will not adhere well in the spotted areas. Does anyone have any recommendations?
Noticed you got-a-few questions. I had mold in the same area but it wasn't too bad. First get a sponge, rubber gloves and goggles and wipe down the mold. Do this several times. Then gouge the spots out and sponge it again. Let dry, patch and primer with 'kilz' primer. You can re-texture and paint . If its not bad this will work. Hope this helps with the honey-do-list.
prime the surface first before you apply the Spackle
If you have mold in your bathroom dont do the bandaid thing. replace the drywall with blueboard or greenboard. these are both mold resistant.
The drywall should be replaced. Use a good quality primer / sealer. Mold / Mildew doesn't just go away. It permiates the drywall.
You can purchase mold killing paint in a number of hardware stores. Go ahead and scrape off the remaining paint, then paint it with the mold killing primer (Kilz), then paint normally. As for the patching: Spray the affected areas with a mildewicide, and then spackle. Paint with mold killing primer, and paint as normal. You might think about replacing the fan as well.
