A milky white haze or mist formed on the surface of the paint film.
Moisture condensing on, and being trapped in the wet film. This may be due to:
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. If these remedies fail to correct the fault, raise the temperature of the paint shop by a minimum of five degrees, avoid all direct draughts, flat and repaint the affected area.
NOTE: Blooming of the colour coat may indicate that the undercoats have been similarly affected, the defect having gone unnoticed due to their matt finish. This may subsequently give rise to blistering or loss of intercoat adhesion
