Spray painting large buildings and commercial property

Spray painting a large building is 10 times faster on average, than using a roller.  The speed of application depends on how fast the paint leaves the spray-gun tip, which in turn depends on how big the spray tip is.  For a given material, say contract emulsion, the larger the spray tip orifice, the faster you will need to move the spray gun.  In a wide open area this may not be a problem, but if the area to be spayed is complicated with windows and doors, this will slow you down and require a smaller spray tip.

The faster the paint leaves the spray gun the more powerful the airless sprayer will have to be to be able to pump the greater volume of material.
