What is an HVLP Paint Sprayer?
The HVLP Paint Sprayer is a paint applicator similar to conventional paint sprayers but uses low-pressure air to push out paint in the most efficient manner. It’s a tool now widely accepted by professional painters worldwide since it allows them to do their job more efficiently and likewise enables beginners to apply even coats on surfaces, a coveted level of skill that was once exclusive only to skilled or experienced painters.
Advantages and Disadvantages of HVLP paint sprayer
The turbine engine used on HVLP’s is the heart of this paint sprayer tool, which frees the user from connecting to an air compressor. Its portability greatly increases the flexibility of use. The low pressure produced by the turbine results in a softer application of paint, lessening over-spray and paint wastage. Transfer efficiency can get as high as 85% and would rival the best high-pressure finishes.
Most HVLP motors create a loud noise similar to that of a small vacuum cleaner. Because the turbine engine uses surrounding ambient air filtered through a dry filter, prolonged use will heat up the air pushing the paint outward. This sometimes causes the paint to dry too soon.
How to use HVLP paint sprayer?
Follow manufacturer’s mixing instructions on materials to be used. Strain for better results. Never overfill the cup. Always perform a test spray to check the consistency of the material. If too dry, adjust air flow control accordingly. If too wet, adjust fluid flow. During application, always hold the spray nozzle perpendicular to the surface being sprayed. Recommended spraying distance is between six to eight inches. Overlap spray material to at least 75% of the previous coverage.

5. In what ways painting with HVLP sprays is different with other sprays?
- Gun distance to the area being sprayed is the most obvious difference of HVLPs from other sprays. Conventional sprays require 8-10 inches distance while HVLPs are up to 6-8 inches only. Turbine powered HVLPs provide the most flexibility whether you are doing a simple weekend project on your backyard or repainting your boat deck.
6. What price range of HVLP sprayers should I invest in?

9. Does the turbine case matter?
- Smaller turbine cases are much easier to cool. All turbine engines have cooling fans that are attached to the same shaft that operates the turbine. This fan rotates as fast as the motor. The larger the case, the more difficult it is to cool.
10. Can I use HVLP paint sprayers to spray walls and ceilings?
- HVLP paint sprayers may be used on walls and ceilings as long as you considerably thin your paints. Since HVLPs are recommended to be used perpendicular to the area being sprayed on, using a 2mm cap for wider coverage helps in applying even coats even when painting at an angle on high wall areas and ceilings.
