From Ken Beauvais of Self on July 28, 2014:
Control the environment in which you are trying to coat.

From Simon Hope of Bilfinger Salamis on September 16, 2013:
Add to this, improvements can be made using air-assisted airless units for actual transfer performance. Also the use of plural pumps on jobs can reduce waste, particularly the heated units as this can improve pot life and quality of finish as well.

From Keith Holdsworth of Eastern Tank on September 12, 2013:
Heated airless spray technology increases transfer efficiency and reduces solvent consumption at the same time.

From Atanas Cholakov of ACT on June 17, 2013:
Coatings transfer efficiency varies significantly, depending on  the surface complexity, geometry and size. You may want to consider masking (encapsulating) of the area if it involves field work. Use a skilled spray operator. Refer to the product data sheet of the paint supplier  for information on pump pressure, correct spray tip, etc.

From José Avendaño of Testers y Multimetros 2011 CA on June 17, 2013:
Initially, we must select a right pump rate, gun and nozzle tip. During application, the painter must maintain an adequate distance from the surface, have good application technique (keeping the gun perpendicular to the surface and moving the hand at the correct speed). They should continuously monitor environmental conditions to avoid painting during high winds and excessive temperatures.
