The Preval Sprayer is an aerosol-based spray system that allows the user to
mix up any paint, chemical or solution and turn it in to sprayable material
through Preval’s patented Venturi Vacuum Process. This process draws the
medium from the attached reservoir and delivers a professional-grade finish
on virtually any surface without mixing the propellant and medium together.
This results in an unadulterated finish with no color change.
