Benefits of HVLP Spraying

Due to the application of the paint at low pressure, it means that there is less overspray and a more efficient transfer rate compared to other forms of spraying. HVLP machines tend to transfer 60-80% of the material compared to 15-40% of a conventional air sprayer.

A higher degree with control of the paint means less masking and material wasted and less money wasted.

They are portable and light and can be transported to carry out work at other sites and premises
