The Preval Sprayer is a convenient, and easy to use professional grade spray system.  It 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 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 colour change.
