Are you sure Ben Moore Satin Impervo Oil was used on the walls, it is
the best most expensive satin finish oil trim paint made. If it was you
must wash and sand the walls, but its maybe 35-40+$ a gallon. Why 2
coats, are you rich, is the color change that much, is your painter
crappy, or are you just a sucker. Satin Impervo will stink and likely
make you sick for weeks.
