During the plastering operation, a large amount of water is brought into the building under construction. Most of this water evaporates from the plaster directly into the air and escapes from the building through open doors and windows, but some is absorbed by the studs, joist, and other wood members. Under favorable conditions of drying, the moisture evaporates rapidly from the plaster, so that a week after the last coat is applied, the wood trim and finish might be applied insofar as the condition of the plaster itself is concerned. The plaster, however, is actually drier than the wood grounds and the door and window jambs against which the trim will be placed, and it is the moisture content of such wood items, rather than of the plaster, that should be used as a criterion for determining when it is safe to install the interior finish. Illuminating and helpful.
