I'm working in Thanhphuphat Furniture (in Vietnam), I'm looking for a way to make "decorative poly molding" (not sure I call it right), plz see attached photo.
I mixed poly with "rock powder" (just translated from vietnamese) and clay, with many mixture ratio, and then I add a little hardener.
But what I got is a very hard stuff, I want it elastic poly.
Thanks in advance.
P/S. I'm looking for the mixing method via google, but I don't know exactly the name in english, plz tell me if I call it "polyurethane" right or wrong?
