Re: Re: [papercreters] Water permeable paint for papercrete.



That is a great idea. Here are some articles that might prove useful toward this end.

Or make a giant pot of strong, cheap coffee. That might help it blend into the woods.

What about some naturally occurring, plant~based stain? We have black walnuts here and, although they are a royal pain in the butt to work with, make a nice stain that is not water proof. Very labor intensive but free.

I found that if I sprayed water on the outside of my papercrete dome on a warm dry day that the temperature on the inside would drop substantially from evaporative cooling. I was planning on painting it at some point to seal it, but this may be too big an advantage to ignore.

The problem is that I can find very little info on water permeable paints. There is a lot on vapor permeable paint, but that will not really help with this application as I want the water to soak in. I may just leave it unpainted, but it looks kind of grey and blotchy so it would be nice if I could even out the color at least. Also I want it to be a slightly dark color so that it blends in to the woods a bit.

Things I am looking into are whitewash, milk paint, tempera and colored chalk powder. Any thoughts?
