What is a disadvantage of high-pressure spray guns compared to HVLP guns?

High-pressure spray guns typically operate at much higher pressures than HVLP (High Volume Low Pressure) guns. This means that while high-pressure spray guns can apply paint quickly, they often result in a significant amount of overspray, which lowers the paint transfer efficiency. In other words, a greater portion of the paint being sprayed does not land on the intended surface but instead becomes airborne, wasting material and potentially causing environmental issues. HVLP guns, on the other hand, are designed to operate with lower pressure, delivering more paint directly to the surface and thus achieving a higher transfer efficiency. As a result, using an HVLP gun can lead to reduced waste, improved coverage, and a more economical use of paint.

While factors such as weight, cleaning time, and cost can vary between different models of spray guns, the primary disadvantage associated with high-pressure systems lies in their efficiency in terms of paint transfer.
