So I'm not mixing it enough then I only put maybe about a quarter inch

It comes out quite thick but dries too quick. Thing is my crappy Nilfisk is shit for snow foam I reckon if I snow foam it thick every week it'll fuck it in double quick time as this one is a warranty replacement. I reckon the old one died because they're a budget washer that can't take snow foam on a regular basis (by regular I mean once a week if that!)
