The streakiness is more probably from the application than the mix. If the
paper isn't sized, and/or rather absorbent, I could see that happening.
But on the other hand we may live on different planets: I always moisten
the sponge brush with a bit of distilled from a dropper & work it in by
hand -- otherwise the dry brush soaks up too much emulsion.

I really really really don't think baume is serious... at least within,
say 25% (tho maybe I shouldn't say that.... tempting fate !) Another
explanation is that I often load up on paint to the max, maybe the water
is needed to dilute it a bit.
PS. But it's 4:39 AM here. I'm not responsible for any reality at a time
like this.
