I have a new dormer shed and a painter said I should wait 2 weeks before I start painting the newly plastered rooms. I"m in the northeast in Boston Area with freezing temps. Is this true? What's the rule of thumb?

Not sure what you mean by newly plastered
If you mean new drywall & taping with joint compound then I haven't heard the 2 weeks thing on that before

New drywall - only a day or two after its dried.
New plaster - 30 days for it to cure, let the ph settle.
Copied from a historic home rehab site:
The key to a successful paint job is proper drying of the plaster. Historically, lime plasters were allowed to cure for at least a year before the walls were painted or papered. With modern ventilation, plaster cures in a shorter time; however, fresh gypsum plaster with a lime finish coat should still be perfectly dry before paint is appliedor the paint may peel. (Plasterers traditionally used the "match test" on new plaster. If a match would light by striking it on the new plaster surface, the plaster was considered dry.) Today it is best to allow new plaster to cure two to three weeks. A good alkalineresistant primer, specifically formulated for new plaster, should then be used. A compatible latex or oilbased paint can be used for the final coat.
