Chalk Run down

Exterior Paint Solution

 
 

Chalk Run-down: The washing down of chalk from an excessively eroding paint onto another area below (a brick foundation, for example), ruining its appearance.

Possible Cause:

Use of a lower quality, highly pigmented paint.

Use of an interior paint for an outdoor application.

Erosion of factory-finished metal siding.

Solution:

 

Remove as much of the chalk residue as possible (see Chalking). Scrub any stained areas with a stiff brush, using a detergent solution; rinse thoroughly. In cases of severe staining, an acid wash may be necessary. Either way, if the affected area dries to a different color, consider painting it with a quality latex paint. Eroding aluminum siding should be thoroughly cleaned (power washing recommended) before painting with a quality exterior latex paint.
