Spray booths are often used for water-based paints and frequently require relative humidity levels as high as 65-75% in order to deliver consistent spray quality. Optimising RH helps prevent aerosol evaporation, pigment agglomeration and premature drying, and ensures consistent deposition rates.
The objective of humidifying a paint spray booth is to permit the optimum transfer of paint from the spray guns to the bodywork, without any loss into the atmosphere of the water-based paint itself. When the relative humidity level drops below 30%, problems begin to arise, one of which is the simple fact that paint dries increasingly fast at this level.
