soft wash painted brick in LaGrange

In LaGrange, this comes up on historic-district houses, college-side streets, and the larger lots toward Vernon Road and Callaway. LaGrange clay does not rinse off a driveway with a garden hose, and shaded brick grows a green film by late summer. Older brick in town often has softer mortar than a new subdivision wall. The method gets gentler, not louder.

January here is gutters full of oak, a porch that needs to look right for guests, and the odd jobs that got postponed all year.

Brick holds moisture, which is why the shaded elevation grows a green film and why painted brick mildews in the pores of the paint. A controlled sodium hypochlorite wash kills that film. Pressure high enough to “clean the mortar lines” is pressure high enough to cut the joints. We do not do that.

Painted brick is paint. If the paint is chalking or peeling, a wash reveals the peel. It does not cause fifty years of failure, and it also will not glue the paint back down. We would rather show you a test area than discover the whole wall is holding on by habit.

Efflorescence, the white salt crust, is not mildew and it is not a bleach problem. It is moisture moving through masonry. Washing the crust off without stopping the water is temporary. We will tell you if that is what you are looking at.

The full explanation, without the town attached, is the brick and mortar are not a driveway article. The town does not change the chemistry. It changes the houses, the shade, and the clay.
