Blooming, or leaching, is somewhat different from blushing. Blooming occurs when the amount of condensate causes water-soluble compounds to migrate from the body of the coating to the coating surface. When the moisture evaporates, the leached components will appear on the surface as sticky deposits.
Severe blush or bloom will also cause significant surface irregularities, and these defects are serious enough to cause additional light scattering, resulting in an even more whitened appearance.2
