HVLP Vs. Conventional Paint Sprayers

    Overspray

    • HVLP spray guns use low atomizing air pressure to help reduce overspray. Conventional paint sprayers use high pressure, which increases the chance of overspray. When this happens, paint can land on other objects as well as in the air within a wider range. Some kinds of paint contain additives or other solvents which make the overspray harmful to the environment. If the paint is wasted, then so is the money spent on it. According to data from Spray Technique and Analysis Research Program (STAR) at the IOWA Waste Center, when HVLP users adjust their spray paint settings correctly, they waste less paint; and therefore save more money compared to conventional paint sprayers.

    Higher Paint Transfer Amount

    • A side benefit of less overspray is a higher paint transfer amount compared to airless pressure models. As the paint streams out of the HVLP nozzle, it is more evenly distributed. The pressure-assist cup-system model feeds the paint to the gun with a separate air line to regulate the paint transfer. With this tool, preparation time is saved because there is no need to protect a larger area as would be necessary prior to using a conventional paint sprayer.

    Best Use of Water-Based Paint

    • HVLP systems work best with water-based paints, which are safer for the environment. Water-based paints are typically more economical because they do not contain the additives of other kinds of paint. Other paints can be used with HVLP paint sprayers. Because less is used, less is needed for the same amount of coverage. Water-based paint, in general, takes takes longer to dry than other types. The drying rate will vary and is based on environment, heat and humidity.

    Clean-Up

    • HVLP paint sprayers are easier and faster to clean compared to conventional paint sprayers. Fewer procedures are needed to rid of the system of toxic chemicals. Even when non-water based paints are used with HVLP spray guns, there is less overspray; and therefore, less time involved in cleanup. Conventional paint sprayers' overspray range is larger, which contributes to the additional time spent in cleanup.

    Cost

    • HVLP systems, on average, cost more than conventional paint sprayers. In 2010, the total cost for a paint spray gun including the fittings and hoses can start from $3,000. If you use one in your occupation, it may be a worthwhile investment. HVLP paint sprayers are used in tanning salons, auto repair shops and building contractors, as well as in many other industries. Over the long run, the investment may pay for itself. The good news is that there are now conversion kits on the market to make it more affordable.
