you should be able to buy it wherever you buy cement, Acrylic bonding agent is usually sold as an additive for concrete or cement. It looks like pva wood glue ie thickish white liquid, . The larger the container the cheaper it is, here in Australia you might pay $25 for a 4litre container at the local hardware, you can dilute it down. It's probably more expensive than pva or latex but it is more water resistant

How expensive are these resins, and where do you buy them.

It has a lot to do with the wicking effect of the fibres in papercrete, plus also controls the expansion and contraction of the paper fibres by waterproofing them, which tends to stop breaking down of the adhesion between the cement and the fibres as they expand and contract. So all in all, it doesn't make the wall waterproof, it controls wicking and it makes the papercrete itself waterproof so it doesn't break down.
Which has got me thinking, the expensive bit of paint is the titanium dioxide, not the acrylic base, since I'm looking at introducing papercrete here in Tasmania where building codes are very strict, I wonder if I could buy paint base cheaply by the 200L drum?.

Perhaps acrylic in Portland increases the plasticity, but waterproofing? What I'm puzzled about, for those folks who add latex in their mix, is how they expect it to be waterproof from a common sense point of view. Waterproofing is usually a property of membranes on the outer surface of a wall such as latex paint. The outer membrane protects against rain and keeps the water out of the insides of the wall. But when you mix everything together, there is no more membrane. The waterproofing material is disbursed into particles everywhere in the wall. So the question is, what good is a particle of latex 8 or 10 inches inside the wall when a rainstorm comes and the water starts soaking in from the outside?

It will make quite a difference depending on what the active ingredient in the deck stain is. If it is acrylic then it may work quite well. I use acrylic in straight Portland powder to make roofing and thin shell things.

Thank you all for your help and input. I am going to try to start soaking my paper today. I think I will make a few garden pots and try one with latex and another with the deck stain and let them sit out for a few days to see how they hold up.
If I make a batch of paper pulp in a trash can does anyone know how long it may last before it starts to go bad? I am assuming that after a while, it may start to mold or smell.

I would like to make a mold to make flat stone type bricks but have so many questions. If anyone has any helpful information, I would greatly appreciate it. If it matters, I live in central North Carolina where we have our share of rain & humidity. Hubby doesn't "get" my projects so most will have to be easy for me to do on my own. But I am handy with a few of his tools.
