A paint spraying booth has a back wall over which a water curtain flows to collect sprayed paint, a tank to receive the water curtain, vertical entrainment ducts disposed above the rear part of the tank, means for generating a flow of air through said ducts to lift water from the tank for the formation of the water curtain, a vertically-disposed wall separating the front and rear parts of the tank and having one or more transfer openings below the water surface, and baffle plates in the front part of the tank causing paint-laden water from the curtain to flow to a remote zone before returning to the transfer opening in order to minimize the quantity of paint passing into the rear part of the tank. A surface-removal device, preferably with a venturi unit, is arranged in front of the transfer opening to remove floating paint and pass it back to the baffled region for further dispersal.
