Hi Judith,
If you look up darjit, you’ll find some info about adding acrylic paint to the mix, esp for cold weather outdoor sculpture.
www.darjit,.com
(taken from their site) Building light weight outdoor garden sculptures:
3 parts darjit, 1 part cement, 10% acrylic adhesive or acrylic paint.
I do know that they have a different recipe for extreme cold, using more acrylic paint. I requested it, I will have to find it. It is to help with the waterproofing and the expansion/shrinkage of the product in cold weather.

Sorry but I may have missed the point of putting latex/acrylic paint into the mix. Is it to waterproof? I have many 5 gallon buckets of it in my closet and was going to use my regular mix then paint the first few courses after they had completely cured. Also was going to do the same thing with a papercrete roof.
Sincerely, Judith

My experience with paint in papercrete is that the PC mixture tends to not bind as well. My different test samples gave me the surprising result that papercrete with paint was slightly more brittle than the just the simple recipe. My straight recipe has performed better in strength tests. It could just be the proportions I put into mine (about 1 part for every 15 parts) and perhaps other proportions could be better. In addition, I am wondering if the paint would add any insulative properties to your papercrete... by filling in the air bubbles it could potentially minimize the R-value. Just a thought, for whatever it is worth, but specifically in respect for your intended use.
