This building’s precast panels were absorbing water and leaching silicate particles onto the glass, frames and mullions of the window system. Additionally, the sealant in the vertical control joints showed signs of adhesive and cohesive failure. Everclear’s solution included: the removal of mineral deposits from windows, frames, and mullions, cleaning of the building, the application of a water repellent to the vertical substrate, the application of a protective coating on the windows and frames, and the removal and replacement of sealant in the vertical control joints.
