The best HVLP spray gun for you depends on your project needs and setup.

Gravity feed spray guns are ideal for smaller projects and offer great control with less waste, especially when spraying at lower pressures.

Bottom feed (siphon) spray guns are better for larger jobs or when you need to spray overhead, as they hold more material.

All Fuji Spray HVLP spray guns deliver professional results.

The right spray cap set depends on the type and viscosity of material you’re spraying. The below is a summary, you can get more details with Fuji Spray's Air Cap Quick Reference sheet.

Smaller sizes (0.8mm – 1.0mm)are ideal for fine detail work or thin materials like stains, dyes, and clear finishes.

Medium sizes (1.3mm – 1.5mm) are versatile and great for general-purpose use with lacquers, enamels, and polyurethane.

Larger sizes (1.8mm – 2.5mm) are best for thicker materials like latex, milk paint, and high-build primers.

Fuji Spray spray guns are easy to clean and swap the air cap set, so many users keep multiple cap sets on hand for different projects. Each Fuji Spray spray gun comes with a 1.3 mm air cap set.

Yes. As the turbine motor is working it will produce heat that is transferred to the turbine case. Remember to allow your turbine 10-15 minutes of rest for every 45 minutes of continuous spraying.

Normally you will require to refill your material cup after 20-30 minutes of continuous spraying. To make it more convenient – consider using a wireless out remote. Allow the turbine to cool off after you are done spraying before attempting to remove the air hose.

Place your turbine on the floor 20 feet away from the spray area. Ensure the area is clean and the turbine can draw in a large volume of cool air. The air hose should be placed on the floor; avoid bends and coils as this can adversely affect the airflow.

Please refer to the Fuji Spray Quick Reference Sheet for guidance to help with your air cap set selection. Fuji Spray advises to use your viscosity cup to measure the run time of your finish material. Needles, nozzles, and air caps are a matching set, be sure to swap all three items when changing being air cap sets.

The Spray Pattern is fan-shaped, so for a larger-sized fan keep your spray gun at a distance of 6″-8” from the surface. Moving too close will increase bounce back while moving too far away can produce a dry spray.

Bounce back occurs when the airflow from the spray gun carries the finish away from the surface you’re spraying. The main causes of this will be holding the spray gun too close to the surface while spraying or using too much airflow for turbine spray guns and too much pressure for compressor-driven spray guns. The closer your spray gun to the surface is and the greater the airflow/pressure, the more bounce back you will observe.

Dry spray occurs when the material cures before it reaches the surface you’re spraying. The most common cause is holding your spray gun too far from the surface. For fast drying finishes, using too much air or too little finish for the airflow can result in a dry spray.

Use the pattern control to adjust the width of the fan to the desired size. Don’t forget to readjust the fluid control to ensure optimal coverage. When using a small round fan pattern to spray smaller surfaces, move closer to the target.

While HVLP Turbine Systems were designed for fine finishing, thousands of people have used the Fuji Spray to paint walls/ceiling and they are very happy with the results. For better results, choose a paint with lower viscosity and a higher tolerance for dilution. Before you begin, make sure to mask all adjacent surfaces. Thin your paint according to the air cap set you’re planning to use. See the air cap set quick reference sheet for guidelines.

You may need to add slowing agents/dry time extenders such as Floetrol to promote better leveling. It’s best to use bottom feed spray guns such as T70. It will hold more finish and the material cup can be readjusted to ensure proper material intake when spraying ceilings. The cup attached to your gun will require constant refills. When spraying large areas it is recommended to use a 2Qt pressure pot.

The viscosity of coatings is important. Although we supply a guide, there is often some experimentation involved in arriving at the best viscosity. If a product is thinned too much, there are runs. Too thick and ‘orange peel,’ or rough finish is the result. When thinning, it is essential to use a reducer that is compatible with the material you are using.

It is wise to experiment on a practice piece to ensure that the finish is perfect. Request information from the coatings manufacturer – don’t forget to mention you are spraying with HVLP equipment. Water-borne lacquers can be applied successfully with HVLP. Some of these products require no thinning whatsoever (but some do). Many of these newer coatings contain a high-solids content of 60% or more, so the turbine must also be powerful enough to handle waterborne products. Several thin wet coats are preferable to one or two thick coats.

Yes, HVLP is ideal for this application – but you must follow a few general rules in order to achieve a good finish. If you intend on spraying latex emulsion paint (house paint) most of the time, please consider purchasing the more powerful 4-stage turbine systems like Mini-Mite 4, Q5 or D6.

To spray latex paints successfully, some rules must be adhered to. The latex should be ‘finish-quality’ (the best grade). For best results, a latex additive should be used. Additives or extenders are not for thinning – it is a product that prevents the paint from drying too quickly – in other words, it is a ‘slowing agent’ – it slows the drying process allowing the paint to level more smoothly.

You still must thin with water. Thin the latex with water – upwards of 20% should be enough. The 1.5 mm – 1.8 mm is preferred for adequate coverage on items like household trim, louver doors, fireplace mantles, cabinets, etc.

When spraying latex, be sure to turn the fluid control to limit the paint to a finer spray. This will increase the ratio of air to paint and result in better atomization and a beautiful finish. (Factually speaking, it doesn’t increase the ratio of air to paint but does the opposite – it allows the air atomizing power to work on less paint, thereby improving the quality of atomization).

Spray the paint on ‘wet like a lake’. In other words, it must be completely wet in order to flow out nicely and look smooth. If you are only seeing droplets on the surface, open up the Fluid Knob for more products. HVLP is designed for fine-finishing, and this includes furniture, pianos, cabinets, automobiles, machinery – anywhere a ‘Class A’ coating is to be applied.

If you already own airless equipment, you’ll find that an HVLP system will complement it perfectly. Although there is some overlap, every family of spray systems on the market has its special place.

1. Use the air cap set 1.8 mm.
2. Thin the paint upwards of  20% with water.
3. Use additives if necessary.
4. Add the 6 feet whip hose to reduce air temperature through the gun.
5. Hold the gun no more than 8″ (20cm) away.
6. Apply a full, wet coat.

It’s the same answer as with any coating – yes… just so long as you thin it appropriately. Spraying of lacquer may be prohibited in your location. Please check with the local jurisdiction.

Lacquer fumes are toxic and flammable (combustible), so adequate ventilation is absolutely necessary. Explosion-proof light switches, fixtures, and an extraction fan are a must.

Lacquers were formulated to dry extremely fast. The very fact that the turbine motors become hot and produce heated air can be counter-productive with lacquers. If you spray as you would with regular slow-drying paints, you may find that you can only spray a dry coat or you get orange-peel. But as always, there are ways around problems like this.

1. Use the standard size air cap set.
2. Apply at least 2 coats of lacquer sanding sealer first, and sand flat. The sanding sealer sands nicely (unlike some lacquers) giving you a perfect base for the topcoats.
3. Thin the lacquer until it levels out on its own (unless this contravenes local rules).
4. Add a lacquer slowing agent to slow the drying process if dry time becomes a challenge.
5. Add another hose to the standard 25 feet hose. This will result in the air passing through the air cap cooler. If you also want more flexibility and lighter weight, choose a flexible whip hose.
6. Get in close with the gun and apply a wet coat.

If all of the above instructions are followed, then a beautiful finish will result. This assumes that the spray gun is held no more than 8″ away from the surface being sprayed (closer is ok). We also assume is that the lacquer is thinned enough. In fact, if you have done all of the above and are still getting orange-peel, you will likely have to thin more. Always use lacquer sanding sealer and thinner/solvent from the same company to ensure compatibility

The Q5 PLATINUM turbine is equipped with a Variable Speed Controller to adjust the speed of the motor. To decrease air pressure, simply turn this dial counter-clockwise. To increase air pressure, turn the dial clockwise.

Overspray can be reduced to an absolute minimum by doing the following:

• Adjust the size/shape of the spray fan pattern to suit the object. This may mean moving the gun closer than the maximum 8″. Thin objects such as spindles or railings can be sprayed with the round pattern and the gun held up close. Overspray is caused by the particles that ‘miss’ the object.
• Thin only as much as necessary and no more. Experiment with less thinning. However, always remember, the paint must be thin enough to level out on its own after being applied wet. Make a note of the thinning for next time.
• Never hold the gun further than 8″ away from the surface. Closer is better.
• Reduce the air pressure at the air control valve. Practice first on scrap material rather than your project. Once the point is reached where the finish starts to suffer, open the air control valve slightly for more air. The complete project can now be sprayed with the same setting for the air. Reducing the pressure is the best way to reduce bounce back and overspray to an absolute minimum. If the finish is not sufficiently thinned, then you will not be able to reduce the air. The paint must level on its own.
• Learn to engage your trigger on and off accurately. Remember, as you come off an edge and continue to depress the Trigger, hundreds of particles are being sprayed into the air. Eventually, this will build up ‘mist’ in the room. The Fuji Spray High-Efficiency Air Caps reduce overspray significantly (installed in all Fuji Spray spray guns).
• Use some type of extraction fan and spray close to it. You may need an explosion-proof fan depending on which product you are spraying – please check with the local jurisdiction.

Fuji HVLP spray guns are simple to use and easy to maintain! Cleaning your HVLP spray gun is as easy as 1-2-3. Simply follow the cleaning instructions and guidelines outlined in this YouTube video, or in this PDF Printable version. Now, you will ensure that your spray gun lasts for a very long time and that it will maintain its peak performance!

1. Remove the fluid knob at the rear of your spray gun.
2. Remove the needle spring.
3. Squeeze the trigger, this will push the needle assembly back far enough for you to grab with your fingers. Remove the needle assembly.
4. Remove the collar from the front of the spray gun.
5. Remove the air cap.
6. Use the supplied wrench in order to remove the fluid nozzle by turning counter-clockwise.

When re-assembling, please replace all these components in the reverse order: fluid nozzle, air cap, collar, needle assembly, needle spring, and lastly the fluid knob. It is a good idea to apply a small amount of lubrication to the needle shaft upon installation. This will help to allow the needle to move freely and seal the fluid nozzle effectively
