Sealants for polymer clay

Apr 5, 2015

Watch Thread
    1. I'm at a rather exciting but scary stage with creating my first doll - after a bit of a break (literally and figuratively - I stepped back for a while after his torso caved in in the oven XD), I've only got very little more to complete before I can call the sculpt finished. I'd quite like to try my hand at a face-up and some body blushing once he's complete.

      I've been sculpting with Fimo Puppen, and would like to make sure it's sealed before going any further with this, but I'm not quite sure what to go for to do this. Almost every spray varnish I've come across has been played by one person, then someone else has said it's not safe for polymer clay - very confusing!

      I'm not sure whether Mr Super Clear may be my best option, but I'm holding back from that as it's quite difficult to source in the UK, so a teeny tiny can costs as much as a big block of the clay I've been using!

      Any suggestions or recommendations, lovely people? :)

    3. When I used to make beads and jewelry with polymer clay, we used to use a brand of floor wax to seal them! Future floor wax was a pure polyethylene coating. We would keep some in a bottle w/brush that they sell for nails in beauty supply shops. The stuff would go on with a satin finish, and could be gently sanded matte as well.

    4. I've used Mr Super Clear and Citadel Purity Seal on Fimo. Both work, but tend to get shiny, especially after several layers.

    5. I recently tried out many layers of PVA glue, it seems to work to seal baked Gray SuperScuplty firm, then I put a layer of Tamiya's surface primer.
      If you are going to do this, makes sure that you have at least 7-8 even coats of glue smoothed over your piece before the gray primer.

      Without the layers of glue in between the baked sculpty and the primer, the primer turns in to a very sticky mess that's hard to get off.
      And Also!
      **Warning**
      If you try to sand or scratch the finished layers, the glue layer will pull up off the clay surface, but it will be very easy to just peel the layer of glue and primer off.
