Ok troops, heres the quandry.... I have a pal living in Oz, she's after Karndean flooring but the guys she's talking to are contradicting themselves regarding sub floor prep. She lives in a pole house and therefore does have a degree of movement. My idea was to 9mm plywood followed by a second layer of 9mm fitted at 90 degree to the first then finished with a flex screed. Goes without saying that it should be screwed down not nailed. By all means, if I'm talking s**t just say. Cheers Jamie
