100 Arlington

Project History

100 Arlington, adjacent to the Park Plaza Hotel and situated between Boston’s Theater District
and Back Bay neighborhoods, was originally constructed for office use in 1927 by the
Boston Consolidated Gas Company. The 14-story Renaissance Revival building features
a limestone and brick facade with two-story arched windows on both the street and penthouse
levels. Renovations to repurpose and modernize the historic building have made it a desirable
location for luxury residences.
After nearly 90 years of exposure to wind and weather, it was necessary to repair the red brick
and terra cotta exterior, interior facing rooftop parapet wall. Conproco‘s Structural Skin
eliminates the need to re-point the masonry substrate and was used to seal the new
wall system and provide breathability, weather resistance and excellent freeze/thaw stability.
K-88 Admix, an acrylic admix used with Structural Skin for exterior walls, promotes curing,
increases bonding and durability and further improves resistance to water entry.
Conpro Lastic, in a smooth finish, was used to coat and provide UV protection and
additional water repellency.
The project was completed in 2014 and won the Boston Business Journal Best in Boston
Real Estate Award in 2015.
