Forgive the length and help this girl...Thanks!!
Situation: New Orleans House built in 1950. Problem area is in upstairs kitchen with peeling paint off plaster ceiling. Above the kitchen is poorly
insulated attic space. Kitchen has circular register/vent in ceiling for central ac/heating. No lead paint. House was empty, no heat/air for nearly a year after Katrina since it was flooded downstairs.
Problems: Plaster ceiling peeling/bubbling paint in spots for at least 15+ years, ONLY in kitchen (walls not pealing). A year ago ceiling was scraped of just the peeling bubbling paint (it was latex enamel, but there was old oil base paint under that pealing paint).
The cracks: There are several long thin cracks running along entire length
of ceiling and quite a few other hairline, small cracks in many places. There is no separation between wire late and plaster. Before the painter repainted, he just filled in the cracks with patch compound,
sanded and did not tape or widen cracks. (The larger long cracks showed up again). He also patched smaller cracks by just putting big patches over larger areas.
The ceiling and repairs were then sealed with a water based primer and painted with latex paint. In a short time the paint began to peal again.
The plaster is cold/cool, solid, off white colored, smooth and hard like chalk board with no chalky residue except in small areas right around ceiling vent from, I guess, moisture.
I started to attempt to remove the old paint layers by scraping,sanding, strip ease, etc. and have reached an impass. After spending > $500 on materials (scrapers, stripeez, drop cloths, masks, goggles, etc) and labor and with 10 days of hard work, it appears that I will not be able to get all this paint off. Then there are the bad obvious repairs that are not smooth and they are unsightly. Also, the old oil base does not come off with the latex and primer so everything that is done takes too much time and some won't come off without gouging the plaster.
The initial layer of old oil base paint is firmly stuck, not pealing ( but I can chip away at it with a trowel and it cracks off like little pieces of egg shell. The latex can be peeled scraped but is nearly impossible to remove
over those bad repairs and in other places. After all this time and money I have about 1/4 of the plaster exposed. (Kitchen is 20' X 14').
1. Can I mud around edges of oil base and sand? Or must it all come off.
If so, how? Stripeez too hard to use on ceiling and didn't work well.
2. Does all well-adhered latex have to be removed? How?
3. Causes of problem: poor insulation over ceiling? Cold ceiling? Poor initial ceiling prep? It appears to be long-standing problem.
4. Besides the bathrooms (which are not pealing), this is the only room with no texture over the plaster...none on wall or ceiling. Is this significant?
5. I'd consider putting thin drywall over ceiling but the ceilings edges are all wonderfully curved in this house. But, can I put drywall on and preserve curves? Can this area be skim coated into walls to preserve curves?
6. Would the NuWal system work? Or would the paint all have to come off
with that fix too?
7. Since walls are not peeling but are contiguous with ceiling (no border), can the latex paint on the wall be preserved?
8. After all is done, repairs, etc. what should I seal this plaster ceiling with to end this problem. I was told by one source, a painter, to use a product that is quite thin and water based and sticky, over the plaster after paint has been romoved (impossible task) and before any patching is done due to temperature of ceiling and then to tape/patch/ and seal again with latex before painting. What about oil based paint?
How do I go about doing all this? In what order?
I'm at the end of my rope and can not afford to do much more but I do want to do this right.
Please help, I'd appreciate it FOREVER!!
