Once people see the natural beauty of a CEB wall, they often ask, "Do we have to cover them?"

On the interior of a home they can be left exposed or finished with a decorative plaster. On the exterior, some recommend a render or stucco finish. There are CEB homes that have been sided with cedar, cultured stone, and even vinyl.

Leaving the walls exposed or using an earth plaster makes better use of CEBs moisture regulation qualities.
