I'm having some difficulties with painting Platsil Gel 10, I was recommended as a cheap solution to buy regular oil colors mixed with silicone. To thin it out I used a small bottle of chemical clean heptane/gasoline. But I'm not satisfied with the look,the substance is to sticky (see the picture)
Any other ideas or ways to get a persistent paintjob done over platsil gel 10 silicone? would be greatly appreciated
Thin gel 10 with white spirit, you can then apply in washes (1 part silicone to two parts white spirit) you can use an airbrush, but will need to clean it constantly to keep it from being completely destroyed (use ipa, acetone, or other solvent) perhaps also get some stipple sponges of varying textures to help blend any brush strokes.
If you're using oil colours, keep addition as minimal as you can as the oils take a long time to dry. I'd recommend splashing out on silicone pigments - they're only about £5 each, and you'll get a lot of usage out of them without the hassles of oils (the pigments mix as the true colour, and do not affect the the usual 10-15 min gel-10 cure time, without risk of stickiness or change of colour once the oils have dried)

I'm starting with Plat sil gel 10 and some people in the forum suggest me to mix first part B with acrylic airbrush paint + Naphta( in italy is etere of petrolium), is it correct?
white spirit is similar to Naphta?
They are both nasty solvents - naptha is more like lighter fluid, white spirit is a brush cleaner/paint thinner. Naptha evaporates way quicker than white spirit, and I've only ever used white spirit as a thinner in this context, so can't advise you there I'm afraid. All I would say is that whichever you choose, get yourself a respirator as prolonged exposure to the fumes is seriously bad for your health!
Here's a couple of useful threads to check out:
Are you planning to mix part B with your pigment+thinner (in your case airbrush acrylic+naptha), then mix with part A to paint your piece? Will you be using an airbrush? My concern if using an acrylic based paint on the surface of your piece is that it would 'crack' as acrylic doesn't bond/stretch in the same way an oil or silicone pigment will, and that your colours may not be true until dry. Perhaps someone else can advise you better here as I have always used oils or silicone pigments as I never felt it worth the risk and like to know for definite how my colours will look!
An alternative to using thinned down gel-10 for finishing is to use pigments/oils mixed with clear RS Silicone or clear Dow Corning 781 acetoxy silicone (can send you links to these products if you like) these are cheaper products, and no need to mix two parts as they are one part sealant silicone in a tube.
Hope this helps!
Sorry, final thing I forgot to mention - you will still need to use white spirit/naptha to thin RS/Dow Corning silicone.
I try to explain the steps that I would do
1_ model no sulfure plasticine
2_ mold in geal coat and polyester resin or plaster
3_Plat sil gel 10: acrylic color in Part B and then mix with A
4_ to paint the skin use oil paints or colors for silicone
mixed with white spirit.
I have an external mixing airbrush I think that does not have so many problems to become blocked.
Is it right color: http://www.amazon.com/Silc-Pig-Silicone-Pigment-9-Pack-Sampler/dp/B...
is all right?
can you give me the link to RS Dow Corning 781 Silicone or clear acetoxy silicone?
this one is very expencive...

Apologies for my delayed response! Step 4 - use oil colours or silicone pigments mixed with silicone (Platsil/RS/Dow), and thin using white spirit.
Here's a link to Dow Corning Acetoxy Silicone http://www.screwfix.com/p/dow-corning-acetoxy-silicone-sealant-781-...
Here's a link to RS Silicone http://uk.rs-online.com/web/p/silicone-sealants/0692542/
I'd normally use these pigments http://www.mouldlife.net/mouldlife-silicone-pigments-1197-p.asp
Instead of finishing powder, I'd use translucent powder (Ben Nye/Kryolan) or a little dusting of talc on a big soft brush. The benefit of translucent powder is that it doesn't leave a white dusting over the paint job, but talc is cheaper and should do the trick so long as you don't apply too much :)
thanks for info!
I would buy translucent powder but mouldlife don't have it...
in Italy is very difficult find anythings!!!
No problem :) I lived in Italy for a while, so understand how hard it can be to find things you need! Translucent powder is more a makeup thing - not sure if screenface do international delivery, but you could always send off an email to mouldlife/screenface to check out what they have in stock and check delivery. Talcum powder I'm sure will be fine, just use it sparingly (do a little test first so you know how it'll look before putting it onto your piece)
I found a powder for make up maybe it is right or amido di riso: rice starch
have you a web site or image of your puppets?
Here's my blog http://theclownspocket.blogspot.co.uk/
I've never heard of/tried using rice starch so can't advise you here. If you try it, let me know how it turns out!
