Being able to wear the hat of a mechanic or engineer is integral to success as a spray applicator, at least according to spray foam industry veteran George MacDonald. Today, this paradigm is relevant as a matter of convenience, i.e. being able to fix malfunctioning equipment on a job site. In spray days past, the self-engineering paradigm was a matter of necessity.
“Most of the equipment back then was hybrid stuff that guys built themselves or cherry-picked parts for,” MacDonald explained.
