Welcome Dan Chiras. ?Are there any surfaces.. Not to use plaster on? ?? can it be used outdoors?

Hello.. I was interested in plaster when Sister inlaw built there home.. I think the cost was prohibitive for her.. maybe you know of Less expensive way's.

I live in Clay soil zone.. is it possible to use local clay// or potters clay.. and add coloring to that.

? What are some creative Dye's or Coloring you've heard of or used?

Thanks.. much
Debra
