Recently my company took a job painting the inside of a home where we used an airless sprayer to spay the walls and ceilings.
We used a semi-gloss paint and airless sprayer and did not backroll. After the completion of the job we noticed during the touch up process that our paint (out of the same 5 gallons) did not match. In fact there was a significant shade difference…why is this?

Infrequently with sub-par paint, a "bad batch" will pass thru inspection (at the Factory) and be sold to a customer… this is the Base Coat batch that is typically tinted to your specs…
It can cause all types of problems such as what you are experiencing…
