Slight blooming may be removed by the use of polishing compound, after the paint film has hardened, or by spraying the affected area with non-bloom thinners. In more severe cases, rub down the surface, and repaint using the correct grade or thinner or non-bloom thinner.
Blooming in paint occurs due to the amount of liquid collected after condensation causes water-soluble compounds to migrate from the body of the paint film to coated surface. When migrated water compound evaporates from the surface, then it will appear as sticky deposits on the top coat.
