plaster problems...
 
hi - i have a 1889 victorian house that someone "updated" in 1975ish with wood paneling. they hammered huge nails into strips of wood all over 2 rooms and after i removed them and the 3 layers of painted wallpaper (not fun) i discovered 8 or so signatures of people who had papered over the plaster - the earliest was 1889.

i decided to salvage the plaster so i cut the damaged areas out (mainly in corners and around doors - some holes- 4 in x 11in) then sprayed the wood lathe and mixed up some plaster patch and put in my 1st layer.
the problem is this: i read somewhere that you need to let plaster dry for up to 2 months before you paint, because you could trap moisture behind your walls and cause damage. there's NO WAY i can wait that long! does anyone know if this is true and if so....can i stop at the 1 layer so far, then just add a bit of fiberglass mesh tape and mix up some joint compound and call it a day?
any thoughts, experience, answers would be highly appreciated!
thanks-
amy

What do the instructions on the plaster patch package indicate?

Yes, this is true.

However, you may want to look into 'emulsion paint'. It's designed to be used over new plaster.It allows the moisture in the new plaster to continue to dry out and evaporate.
