Spray painting gives unequaled paint finishes for cars, furniture, and countless other projects. However, learning the skill requires time and bulky equipment. Who has time to learn and the storage space for those?
The HVLP sprayer is the practical answer, and this page presents the best HVLPs out there so you can decide which sprayer is the right one for you. Keep on reading to find out which model suits your demands.
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.
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 outwards. This sometimes causes the paint to dry too soon.
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.
Conventional sprays require higher air pressure to operate, producing too much overspray and paint wastage, not to mention the level of skill required to operate this tool. HVLPs spray out high volumes of material in low pressure. This gives you a professional finish regardless if you are a skilled or an unskilled painter. This translates to huge savings on paint and labor costs.
No. All HVLP sprays, just like conventional spray guns, must be matched to the desired application. Those used on simple touch-ups are very different from those used on large-scale, industrial applications. When choosing your HVLP, keep in mind what you intend to use it for and consider the long term applications you may have in mind.
There are a number of possibilities why your HVLP is not working and may require disassembly. These include a clogged nozzle or air cap, clogged material hose, or clogged cup pressure tube. Simply clean out the parts and re-assemble. There are instances when the cup seal may be broken, and thus may require replacement.
More often this is not possible. However, there are spray guns that may be converted, but the available air caps are limited. Internal porting is usually the route for conversion which proves to be difficult.
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.
This greatly depends on the application you foresee. However, there are HVLPs that are capable of getting the job done from small projects to large tasks. There is no do-it-all HVLP in the market that can be used for mild touch-ups to industrial application. A good all-around HVLP may be pricey from the start but long term use will actually pay for itself.
There is a wide acceptance of HVLP guns in both household and industrial applications. The ease of use and portability attracts beginners in painting while paint savings is the main consideration for industrial use. If you operate a shop with two shift painters, the savings in paint expenditures will be greatly reduced.
An HVLP sprayer can be cleaned in less than ten minutes. Depending on your familiarity with the tool, it may take considerably less time as you get comfortable in disassembling / assembling without fear of breaking any component. Always consult the manufacturer’s instructions.
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.
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 smooth when painting at an angle on high wall areas and ceilings.
Not all HVLPs are created equal. Each one is designed to be matched to a specific application. In this round, the overall winner is the Wagner 0529021 Flexio 890 HVLP Paint Sprayer Station. It is the only one with an adjustable spray pattern, material flow, and air power all on the handle. This eliminates the frequent adjustment on the base, allowing you to adjust settings on the fly. For beginners, this greatly lessens the learning curve. For professionals this is simply practical. The Flexio also covers the widest area (8” x 10”) in five minutes. This is the feature that makes it stand out.
