Stucco and simulated stone
on old brick.
February, 2017- Washington, DC-
These turn of the century townhouses were originally exposed brick, but covered with stucco probably between 1930-1950
Old bricks were soft and porous, and solid masonry walls leaked. Brick mortar before 1930 usually wasn't cement, but just lime and sand. Lime and sand dissolves in water, and requires constant repointing.
Stucco, and simulated stone stucco, like Formstone and permastone, was a solution.
