Hi Gary!

Great and very needed post, thank you!
I have tested Kremer lime and my plasterer also worked with it on several projects. This lime may be difficult for the novice. Here is a tip on handling this lime.
Kremer lime needs to be vigorously whisked adding a little of distilled water until it becomes like a sourcream (consistency) a few days before the use, then whisked again before mixing with sand. If this is not done it is very likely for kremer lime to crack.
Now I only use lime from Italy.
