Stucco façades will eventually crack, spall and blister as a result of the harsh New York climate. These unsightly blemishes not only affect the aesthetics of a building, but they also compromise its integrity. Cracks open to moisture can suck in water like a straw, leading to interior wall deterioration. If left alone, the trapped water in building walls can foster mold growth and lead to structural deficiencies. The appearance of façade cracks and failures are signs that a building is in need of serious professional stucco repair and restoration.
There are two types of stucco façades: cementitious (which is typically multiple layers of cement-based materials on lath) and Exterior Insulated Finish Systems, otherwise known as EIFS.
Cementitious stucco systems, usually found on older homes and buildings, provide a rigid façade that can withstand harsh environments. Professionals trowel them onto a mesh, which is mechanically fastened to a substrate. The multiple layers create a thick, hard cement protection for the house or building envelope. Unfortunately, its rigidity is also its downfall, since it can’t physically move without cracking.
Exterior insulation finish systems (EIFS) contain an insulation board attached to the substrate, with a mesh impregnated acrylic-based cement layer and acrylic finish coat. These systems offer the ability to create architectural details with ease and provide water repellency. Unfortunately though, installation errors have plagued these exterior insulation finish systems with devastating effects and given them a bad reputation. Cracks, spalls and degradation must be repaired with specially formulated coating systems that will not only protect the structure, but also enhance the building’s appearance.
