Cement Plaster Water-Ressistive Barrier

Tech Tips received a CSI National Communications Award September 23, 2011 at the national convention. 

The code includes two very different requirements for exterior wall water-resistive barriers (WRB). When using cement plaster exterior finishes, ensure the WRB is equivalent to two layers of Grade D paper, and not Type I (No. 15) asphalt felt. There is a big difference between the two. Find out what it is.
