I want to use mostly clay in my first coat, then a mix of clay, sand/silt, wheat paste in second and final coat I may use linseed oil.  The truth is, I’m clueless!  I put a test spot of clay on straw today and it won’t dry.  I have no idea what that means.  More clay, less water?  I have been reading so many contradictory things that now I’m confused.  I thought this would be simple but I need a little guidance.

How long did you wait? As, clay need more weeks to dry!

Weeks??  Everything I’ve read makes it look like you wait two hours and then can do the second coat.

Depending on the weather and climate and the substrate, a base coat of clay plaster 1" or so thick should stiffen up within a couple of hours, enough to not be workable, and firm enough to add more. It would probably not have dried enough to finish shrinking, meaning that both layers would still want to shrink, and you might get deeper cracks. In cool damp conditions, it may take longer.
