Culture of Baltimore - Formstone

Formstone

A tour through many of Baltimore's rowhouse neighborhoods will reveal a façade style not found in many other cities, Formstone. Introduced in the 1950s, Formstone was a modern day solution to early Baltimore brick that was so poor it needed frequent painting to keep it from deteriorating. But soon Formstone became an icon of status for many homeowners.

The appeal of Formstone was that, once installed, it required virtually no maintenance. Salesmen boasted that the insulation lasted forever and that the first cost was also the last as no upkeep or repair was required. Salesmen also pointed out that Formstone was also about one-third the cost of other façade improvement solutions. Its colorful stucco-veneer gave a stone-like appearance that could be shaped into different textures. Formstone was particularly popular in East Baltimore, where residents believed that the stone imitation made their neighborhood resemble that of an Eastern European town, which some thought had an appearance of affluence.

Patented in 1937 by L. Albert Knight, Formstone was similar to a product that was invented eight years earlier in Columbus, Ohio, and called Permanent Stone. Permanent Stone was also a veneer. In the 1970s preservationists and rehabbers felt that Formstone took away from the historic and architectural value of the homes and many had it removed. This can be a costly and time consuming process. Once removed, the brick requires a thorough acid-wash cleaning and then repointing of the grout.
