Once this is addressed efflorescence will usually diminish and eventually disappear. ...

HFS assisted with the restoration of glazed brick and terra cotta by providing custom tinted Jahn M100 repair mortar and Keim coatings that replicated the various surface patterns of the masonry units. **Postcard and history courtesy of Bay Area Radio Museum and NoeHill San Francisco. ...
