TURN ANY PAINT INTO AN AEROSOL SPRAY

The Preval Sprayer allows you to spray up to 473ml of almost any paint or liquid.

The Preval Sprayer is easy and efficient to use.

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 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.

Automotive touch-ups, patio furniture, fences, planters and even art projects will look like new with the help of the Preval Sprayer. Make your car look amazing just in time for summer. Preval is portable and perfect for touch-ups that works on any surface including metal, concrete, wood, pottery, ceramic and glass and is compatible with any exterior paint, stain or dye.

The Preval Spray Gun is a convenient, and easy to use professional grade spray system. It dispenses nearly any paint, formula or solution and its versatility makes it useful for projects from automotive to arts and crafts and every industry in between.

SPRAYER DIRECTIONS
FILL - Strain paint using a medium mesh (225-226 micron) strainer. Thin paints and finishes using instructions supplied by the manufacturer. Pour strained paint or liquid into the product container. Fill container to desired level, do not fill the container above the line on the shoulder. Screw safety cap into place. Shake up product in product container prior to attaching to Sprayer.

ATTACH - Secure dip tube firmly into the bottom of the Sprayer. Remove the filter at the bottom of the dip tube for latex paints and thick paints. Attach power unit, and align red insert (1) opposite air vent (2) on coupler. Attach the product container into the coupler by turning counter-clockwise. Once product container has been attached to the power unit, Never shake the Sprayer . Shaking the Sprayer will disrupt the spray and cause it to sputter or cease spraying. If this occurs stop and let the unit rest for 45 seconds.

SPRAY - Start spraying with the Sprayer in motion and release the button while the Sprayer is still moving at the end of the stroke to avoid runs. Overlap strokes, do not tip past 45° or product can leak from the vent hole located at the bottom of the power unit. The power unit is vented and, therefore, spraying between a 90º angle and 45º angle is required or the unit will not work. Hold the sprayer upright, 15cm to 25cm from the surface being sprayed (12cm with lacquers and other quick drying finishes). If you are too close to the surface, paint will build up too quickly and will run. If you are too far away from the surface, the paint will dry before it reaches the surface and dimpling will result. Keep the Sprayer moving constantly. For best results apply 2 or more thin coats as opposed to 1 thick coat. Spray at room temperature. Begin your project by spraying off workpiece, start to move back across, release button after moving completely off workpiece, repeat process with 35%-50% overlap. Starting and finishing off workpiece will lessen chance of “hot spotting” at beginning or ending of paint stroke.

 

TESTING THE SPRAYER
Practice spraying on a piece of cardboard or scrap metal if you have never used a Preval® Sprayer. Allow sufficient time for product to flow up the dip tube and through the nozzle. Spray for 15 seconds to prime valve with product. If after 15 seconds the Sprayer starts spraying there is no need to back flush. If Sprayer is spraying, it is primed. If clogged, see clogging in trouble shooting section below. Add additional thinner as needed. Please see Thinning Guide for our recommend usage. Remove filter from the bottom of dip tube for thicker paints. Do not shake the unit.

Note: The power unit is vented. Do not tip beyond 45° or liquid will run out the air vent preventing efficient performance.
The actuator orifice is 0.08128cm.

Trouble Shooting
Clogging - Remove power unit from container and remove strainer from dip tube. Install power unit on container. Hold a rag over the red insert in the button and push the button down for three seconds. You will see bubbles in the liquid as the clog is pushed out of the unit. Spray water or solvents through the sprayer to clean the unit. If the power unit gets cold, wrap it with a warm towel to bring it to room temperature or the pressure will get too low. If this does not clear the clog, replace the button as product may have dried in the button. The sprayer may not work if shaken, let the unit sit for 15 seconds before trying to spray again. Install strainer on dip tube. If spraying thicker latex paint, hold a rag over the red insert in the button and push the button down for three seconds.
You will see bubbles in the liquid as the paint is returned to the container. This will lubricate the passages in the power unit and allow smooth paint flow through the nozzle.

FREEZING - If the Preval power unit becomes too cold from continuous spraying, you may see sputtering or a decrease in power. Spray at room temperature for best results. Let the unit rest until it reaches room temperature before trying to spray again. If this does not work, wrap the unit with a warm towel to continue spraying.

CLEANING - Remove the power unit from the container immediately after use. Cap and store the unused liquid. Clean the power unit by placing the dip tube in the appropriate solvent and spraying until clean. If you are reusing the product container, clean with the same thinner used to clean the valve.

HANDLING - The Sprayer is classified as Limited Quantity or Consumer Commodity which means a material that is packaged and distributed in a form intended or suitable for sale through retail sales agencies and is a hazardous material which is packaged as authorised within the Limited Quantity provisions and is intended or suitable for sale at retail agencies.

RUNS - The Sprayer is to close to the surface or you are spraying to slowly across the surface. Spray 20cm- 25cm away.

ROUGH, PEBBLY SURFACE - The Sprayer is too far from the surface or your spraying to fast across the surface. Spray 20cm - 25cm away.
