Hey all, 

 

I'm so glad to have discovered this forum! There is already so much I have learned in a couple hours of browsing. Thank you for the many contributions and for the continuation of this community : )

 

I have one particular question as I jump in here...Will a layer of gesso, varathane, primer, epoxy, etc. in between baked clay and spray paint work as a protective barrier against the spray can's solvents? So if each "lll" is a layer it would look like this: clay lll sealer lll spray paint.

I'm just guessing there would be no guarantees that such a barrier between cured PC and spray paint would be effective. My guess is also that the solvents in oil based paint might well break down any barrier you are trying put in place, especially because of the potential difficulties with mixing water based and oil/solvent based compounds. About the only thing one could do would be to experiment, knowing that often chemical interactions between questionable compounds and PC can take many months to appear. This was the case early on in the history of PC when people used nail polish to achieve a shiny finish, only to find that over time the nail polish caused the PC to break down. Is there any particular reason why you'd prefer to use spray paint? Perhaps there might be another solution we could suggest.

Hi Anita, and thanks for your response. After posting this question here, I was able to find an artist in Cyprus that has successfully used an automobile primer between cured clay and spray paint. The primer was itself from a spray can as well, so it made things pretty interesting. Here's the brand he suggested: http://www.plastikote.com/products/Primer/Sandable-Primer.html

 

I am going to run some tests with the spray cans I have now (Plastic and Universal versions of this http://www.montana-cans.com/products/Cans/NEW_Montana_TECH/Montana_PRIMER_400ml/317   ////////\\\\\\\\&&& http://www.montana-cans.com/products/Cans/Montana_TECH/Montana_VARNISH_Spray_400ml/331) on Premo, Super Sculpey, and Sculpey III. 

There are some preferences application-wise, but I mostly want to use spray methods of priming/painting because I already have spray cans. My Spray paints are much better quality than my acrylic tubes, so I'd like to incorporate them into PC use if it'll work somehow.

Sounds interesting! Please consider posting your results here. A good thing to keep in mind is that I have read reports of polymer clay breakdown that occurred as long as a year after being finished with a substance that eventually reacted with it over time.
