I wish I could remember how many coats I did, but if I'm not completely out of memory, I'd say I did three, because of that habitual personality feature I've got. However, I'm pretty sure it did look good already at two, and if you layer it on top of a similar color, only one coat - you know, I just have to add that third coat to see if the color will deepen.
Maybe not that easily acquired for those of you outside of Brazil, but if you have a friend in the country in question, maybe they can hook you up!
Swedish word of the day:
frekvens -noun frequency
Even colors have one.
