NEW YORK, NEW YORK

Project History
Chatham Towers is a lower Manhattan landmark. Designed
by Kelly and Gruzen, the dynamic twin 25-story buildings are
a testament to the strong architectural styles of the 1960s.
Previous repair work had failed. Large patches of unmatched
mortar were clearly visible and gave the towers a mottled
appearance. A primary concern, for both architect and
contractor, was matching both the original color and pattern.
The concrete had a pronounced wood grain texture with bug
holes and voids. Howard L. Zimmerman Architects specified
and pre-matched the color of the Matrix, M3P, and M3P Stain
to the original concrete. Quality Building Contractors skillfully
replicated the subtle patterns in the primary formwork. M3P
and semi-transparent M3P Stain were chosen to blend and
minimize the appearance of old and new repairs. The mineral
silicate coatings both added subtle color uniformity without
giving the towers a painted look. In addition, M3P and
M3P Stain are effective water repellents and protect the
structures from water damage and carbonation.
