RE: [papercreters] Re: Papercrete Garden Wall

Acrylic is used in the concrete business as both a sealant and an adhesive.  Assuming that nothing is proven and that we are all experimenting.  Many who use latex are not always going for water proofing but are trying to make papercrete last in a wet application.  It is possible that latex in a mix is coating individual paper fibers a therefore slowing the rotting or break down process?

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.
