Blush

Description

A cloudy or dull surface appearance due to the condensation of moisture on the surface. Blush appears on paints and varnishes due to the rapid evaporation of solvent which lowers the surface temperature below the dew point temperature. Blush can be avoided by using a solvent with low volatility or by applying the coating in a dry environment.
