CONCORD, MASSACHUSETTS

Project History
The Thomas Pellet House, located in Monument Square,
is one of the oldest homes in Massachusetts.
The oldest part of the house is the rear ell, built by
Thomas Pellet, which dates from the 1670s. The main
part of the home was built in 1728 by Benjamin Barrett.
The home’s most important architectural feature is the
imitation stone, stuccoed façade, which is attributed
to Barrett. The limestone and horsehair based stucco
was applied to a wooden lathe and then scored to look
like stone blocks. Approximately 80% of the stucco,
and 100% of the original lathe, remains intact today.
Since invasive treatment of the existing substrate
was not an option, consolidants were used.
Conpro Start was used to strengthen the existing stucco.
Conpro Point 5 was used to increase adhesion to the
existing paint, which could not be removed for fear
of damaging the stucco. Conpro Lastic was used as
a protective coating.
