The tape can retain greater than 50 percent by weight of mortar applied according to the Vertical Mortar Receptivity Evaluation. The article includes a substrate, the tape, and a composite layer comprising at least one of gypsum, lime, or cement. The composite layer is at least one of dried or cured on the second major surface of the fibrous layer. Methods of making the article are also described.
