Hi Judith, even though I'll a painter I am not an expert on the chemistry of paint and can not answer that question. I do know that paint should be mixed well even if it sits around for a short period of time to get the maximum benefit of the paint. You know how when you go and buy paint they shake it for quite awhile. Mixing paint by hand is best done by using a stir stick to pull up the material from the bottom. But if I were to say any thing about this I would say to run my hand along that bottom row (the first row we poured where we added the paint to the mix) and see if you can feel any slickness to the surface compared to the rest of the rows. If you feel a difference then I would say that it was of benefit, to what degree I couldn't say unless I was there. Another test would be to put some water on the wall and see if you can see any difference in absorption from the paint mix to the non paint mix. This is a guess on my part. Sure is pretty, though <smile>
Good point Ev. Does that mean the the paint is ineffectual?

It probably depends on the amount of paint that is used and how well the paint is mixed before it is put in (if the paint has been sitting around long much of that makes paint paint has settled at the bottom and should be mixed well to coordinate it back into the rest of the liquid.); and, I would imagine, how much water is used in the mix.

The term "kick" is used to describe set-up time. If we have found one flaw in F/C it is the length of cure time. I found by accident that latex paint has an effect on the cure time. Whilst doing a workshop at Lost Valley we thru some discarded paint in the tow mixer. As usual we did not use it all and I simply covered it for the next days class. Imagine my surprise to find a half full tow mixer solidified the next a.m.!! I have since been using latex to cure times more reasonable and to add some moisture resistence to the mix.
Yes, F/C stands for Fibrecrete which is none other than P/C papercrete. I particularly refer to a mix that utilizes emulsified fibre, portland cement, lime, clay, and sand. It gives me the non-shrink material necessary for the plastering of bare strawbales.
No, there is never such a thing as a stupid question...... maybe some dumb answers though?! hahaha
