Abstract
A plaster screed is made of two metal parts of uniform cross-sectional configuration. The two parts overlap, each part providing one of the sides of the channels. The first part provides a laterally projecting attaching flange as well as the channel bottom, the channel bottom being extended beneath the channel side provided by the second part as well as beneath its laterally extending attaching flange. The attaching flange of the second part is stepped so that the bottom of the screed is essentially flat. The area of the step just beyond the terminus of the first part provides a rearwardly facing groove filled with a suitable thermoplastic sealant. The sealant complements the parts to provide a flat base free of moisture traps while allowing slight relative movement between the parts for relieving stress that otherwise would build up in the plaster material.
