Cement Stucco is plaster with a cement base that is typically applied in three layers over framed and solid walls. Pigment may be mixed in or stucco can be painted. The can be finished with a variety of textures: smooth, raked, or swirled. For an extra coarse finish, sand -or even pebbles- can be mixed in. Different kinds of cement are used in the stucco mixture depending on the climate and texture desired.
