Crack resistant coating for masonry structures

摘要

Masonry structures are susceptible to cracking due to distortion caused by movement of their foundation, vibration, and/or drying out subsequent to the construction of the structure. Such cracking often occurs after the structure has been painted. This results in the crack being transmitted through the coating of paint. Upon repainting of the masonry structure new cracks often develop and are transmitted through the paint coating within a short period of time. This invention discloses a crack resistant coating for masonry structures comprising: (1) a crack absorbing layer which is contiguous to the masonry structure which contains beads which are essentially spherical and which are bound by a resin binder, and (2) a conventional coating layer which is contiguous to and covers the crack absorbing layer.
