What are some ways to improve transfer efficiency of airless spray application?


Selected Answers

From Ricardo Márceles of Pintuco on May 28, 2019:
The percentage of solids by volume must be taken into account for the correct choice of nozzle orifice; The selected fan is also very important to apply only in the area that is needed. The pressure can be regulated.

From Bryant Chandler of Greenman-Pedersen, Inc. on May 24, 2019:
The responses from Anthony and Greg are very good, but also consider reducing the viscosity without adding solvents. This can be accomplished by making sure the coating is as warm as possible consistent with the PDS, especially in the winter time.

From Anthony Allegra of Sherwin-Williams on May 22, 2019:
Spray at the lowest pressure that will atomize the material being applied. There are also some good double-orifice tips being made in sizes that will accommodate high solids materials. These will lower the pressure needed to atomize and cut down on tip wear.

From Greg Hamilton of Port of Seattle/FTINW on May 14, 2019:
Proper gun angle, triggering, tip size and proper fluid pressure all in conjunction with adequate training can improve transfer efficiency of airless spraying.
