Due to the New York’s harsh climate, stucco facades can crack, blister and spall. These unsightly imperfections not only affect the building’s aesthetics, but also compromise its integrity. Cracks that are open to moisture can trap water like straws, leading to interior wall decay. The trapped water can cause mold growth and structural problems if it is left untreated. Facade cracks or failures indicate that a building needs professional stucco restoration and repair.
There are two types: Exterior Insulated Finish Systems (or EIFS) and cementitious, which is typically multiple layers made of cement-based materials on the lath.
Cementitious stucco is a type of cementitious stucco that is used on older buildings and homes. It provides a stiff facade that can withstand harsh environmental conditions. They are rolled onto a mesh and mechanically attached to a substrate. Multiple layers form a hard cement shield for your house or building envelope. Its rigidity is its weakness, as it cannot physically move without cracking.
EIFS consist of an insulation board attached on to the substrate with a mesh impregnated acrylic cement layer and acrylic coat. These systems can be used to create architectural details and are water-resistant. These exterior insulation finishes systems have been plagued by errors in installation, which has led to a poor reputation. Specially formulated coating systems can be used to repair cracks, spalls, and degrading structures. They will also improve the building’s appearance
