I read someone's comment in a bus post on Instagram that the person better paint/seal their spray-foam before they install the ceiling otherwise the little dust from the trimmed surfaces will forever be raining down through the cracks and crevices. I read it as 40% -"this has happened to me"
, mixed with 60% -fear/conspiracy.
The 40% side made me wonder if painting really could prevent some fallout, or even off-gassing. Anyone heard or experienced issue?
