BILLERICA, MASSACHUSETTS

Project History
The storage buildings on Dunham Road in Billerica are
constructed of single-wythe block. The 12 inch CMU are
a combination of split rib, split face and single score units.
The buildings had previously been coated with standard
exterior paint. The paint was deteriorating, and allowing
water entry. Conproco recommended a cleaning and
repair procedure, to be followed by the application of an
elastomeric coating, Conpro Lastic, on the split rib and
single score units. The split faced block would be coated
with a clear water repellent, Conpro Shield M, to allow
the architectural detail of the exposed aggregate to
remain visible. Repair work on the first building included:
mechanical removal of the existing paint, repointing,
removal and repair of sealant, and installation of additional
flashing. A surface primer, Conpro Point 5, was used
as a conditioner, following the mechanical cleaning.
Conpro Point 5 improves the adhesion of acrylic coatings
to concrete and masonry surfaces, and improves coverage.
