The Preval Sprayer is an aerosol-based spray system that allows the user to mix up any paint, chemical or solution and turn it into sprayable material through Preval's patented Venturri 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. Easy replacement and cleanup with interchangeable and disposable parts. Use with the medium of your choice and custom mix your own colors. Store medium in the included lidded containers.
