150 grit screens worked like a charm! But my arms are sore today after all that sanding!
I always give a light quick sand to walls (on repaints) anyways, but its' usually a quick pass that might get rid of a few little picks and maybe the odd lint here and there. And again between coats.
But considering the amount of lint on this job I was extra vigorous on the sanding and pressing quite a bit harder to ensure I get most of it out. And covering every inch of surface. Kitchen, Living room, entrance, hallways, 2 bedrooms and 2 bathrooms. Ceilings too!
I think I'll be feeling the aches in my shoulders tomorrow.
