Alright you lovely Plasterite makers, after some time has passed I can see that the amount of salt that I/we put in the mixture is way to much, it appear to come out of the plaster after a while. So I reduced the amount I put in; now I have reduced the salt volume to a tablespoon for a 25 pound bag, and we shall see the results from that change.
I do not want to completely eliminate the salt for all its minerals present within, but I have been putting in way too much.
New pictures coming soon
