Acrylic patina help PLEASE

Hi all,

I am new here and am praying that someone can help me. I do clay sculptures (current one is a sea mix clay) and I am having issues with my patina of choice. I painted the clay with an acrylic and applied a acrylic polymer emuslsion top coat. The top coat has cracked (almost looks like a crackle glaze) which would be okay if it didn't start lifting the paint.

I have no idea what has happened. Is it because I didn't seal the clay to start with? WHy is the polymer cracking and lifting the paint? What can I do at this point to correct.

I will love you all forever for any help

I don't know what sea mix clay is, but it sounds like either your paint and topcoat were incompatible, or that the top layer dried before the bottom layer-- both things that would cause crackle. Always read all the literature with each poduct-- if not before, then after.
Taking my own advice

hi, my guess is that the clay dried out and cracked, causing the layer of paint to crack also.
What is "sea mix clay"?
Have a great day,

Is this clay fired in a kiln?
