Heya mate, I did use about 2 bottles All up. As I went for the burst effect I wouldn't be able to say how much would be needed to get an even deep tone all over. If the sides (wall) are anything to go by I did I think 7 coats on them, and that was about half the stain of 1 bottle. I did only 2 intensifying coats over all and like 4-5 on the edges to get the burst effect really happening.
