"On interior walls, brick veneer is laid similarly to tile."
Thin, adhered, brick veneer can also be used on exterior walls, but it must be adhered to a layer of traditional stucco or cement board, installed with the same waterproofing measured as would be used on a stucco installation (enough mortar breaks or spacers to allow drainage, two layers of lapped tar paper, flashings and a weep screed). However, corner pieces, either supplied from the manufacturer or mitered, glued and "dusted" by the mason, may be needed to avoid a two dimensional "wall paper" look.
For those who can't afford or justify covering the whole house with brick, a combination of brick and stucco can be a reasonable alternative. For inconspicuous areas, the stucco can even be colored and carved into a brick pattern. A trained eye can usually tell the difference, but a really good job can result in walls that are nearly indistinguishable from real brick.
