Although the coating worked

Elastomeric wall coatings (EWCs) are an important part of new and remedial construction, protecting cladding from water penetration. Assuming they are properly applied, premature failures of EWCs typically involve their manufacturing formulation—degradation due to inadequate ultraviolet (UV) radiation resistance,
or cracking due to inadequate low-temperature crack-bridging ability. The photo below shows a problem caused by formulating, but not by the manufacturer.
