I have "wetted" the wall quite a bit before applying
the plaster. I usually let the water soak in and
then wet it again.

I have only tried using plaster of paris once. Most
of the time I add sand or marble dust. I have seen
mention of adding "hair" to the mix. Do people really
do this?

I am trying to build a basic level of experience with
plaster before I move on to fresco. So, any advice
or reccomendations on mix precentages and consistancy
and finishing techinque would be most helpful.

I will look at the online lime organizations today.

Thanks
