This is a concrete structural wall in a winery where Liso was used but not cured or sealed. This lead to microcracking. 

Liso is a cementitious curing patch designed for filling and smoothing interior and exterior vertical concrete surfaces and non-wearing horizontal surfaces.  Always follow instructions on product packaging and/or technical data sheet.  Finishing instructions for Liso state, "Follow standard ACI curing practices. Exposed surfaces should be cured with a membrane forming cure and seal compound such as US SPEC Hydrasheen or US SPEC Hydrasheen 30%."
