I am new to fresco painting and have done a couple of panels with very good results. The sand I used to mix with the lime paste came from a mosonary yard and I think it is too coarse.

I have read about "river sand" but have not been able to locate where to buy it.

Any advice people can give me about where to find river sand or what other types of sand works well would be much appreciated.

Also if someone could describe to me how smooth the final surface shoud be before you begin painting.

Thnak you
