I would say add more cement and don't worry about the borax. Are you in a wet climate? I have never sprayed papercrete so really have no business giving advice but you're getting it anyway.

I plan on spraying on a stucco on the out side of my PC walls. Is borax or anything else really necessary or is a inch thick layer of stucco well enough to stop anything. If borax is recommended then how much? I also do not know if anything else like paperer should be added to the spray on stucco. I am at the mixer building stage was building one 300gal ran into a design change and am now almost finished with a 200 gal as well. I work 50 hr week and have other projects when I get home, but keep plugging forward on the dream. Thanks Mike south TX.
