Project History

The I.M.Pei design office building was constructed in 1971. The architectural style is “Brutalist” which celebrates the use of raw concrete. The new owners of the building felt compelled to improve its “curb appeal”, after finding it hard to attract new tenants. Many local residents and  preservationalists expressed concern at the thought of “painting” this landmark. After discussions between the architect and Conproco it was decided to use M3P Stain in a limestone color. M3P Stain chemically reacts with  cement providing permanent protection from water entry and carbonation. Unlike paints, M3P does not form a film; therefore it cannot peel, blister or flake.  The natural appearance of the stain makes the  application practically undetectable.
