I would recommend to try nebulising systems which are either powered
by air pressure or ultrasonic waves. Stephen Michalski and Carole
Dignard published an article about the ultrasonic mister in the JAIC
Summer 1997 which explains the self made set up and the problems of
powdery, matte paint. In my degree work in 1998 I successfully used
an ultrasonic mister for consolidating powdery paint (esp. chalk
drawings on installation objects by Joseph Beuys). As far as I know
there have been a lot of projects using updraft nebuliser or
ultrasonic mister for consolidation of powdery and matte paint so
far--in USA, Great Britain, Germany and so on. If there are any
further questions I am happy to help with more information.
