WILMINGTON, MASSACHUSETTS

Project History
When Conproco inspected this project, heavy water stains
and considerable efflorescence were evident on the interior
walls, a clear sign of water entry. The building is constructed
of single-wythe block (12 inch CMU), both split face and
smooth face. The previous coating did not adequately fill
the pores in the block, and was peeling off and cracking.
Conproco recommended a cleaning and repair procedure.
Cleaning consisted of the mechanical removal of existing
coating. Repairs included repointing, the removal and
reapplication of sealant, and some flashing work. A surface
primer for acrylic coatings, Conpro Point 5, was used to
improve adhesion by consolidating the surface. The final
step was the application of two coats of Conpro Lastic,
a flexible and breathable elastomeric coating that bridges
minor cracking and retains elasticity at low temperatures.
Two coats form a weatherproof barrier, preventing water
entry and forming an anti-carbonation membrane. Water
entry has not occurred since the project was completed.
