Hi,
Me and my wife are really new with making resin figurines. And hope some one can give us advice on what Paint to use etc.
We recently tried painting our resin figurines. However a few difficulties arose. When we are painting the paint clumps up very quickly, and it makes it very hard to makes smooth and clean brush strokes on the figurines. Number 2 is that we have a lot of "nookes and cranies" in our figurines, and so it is very hard painting in those areas without messing up other areas. Can you recommend a certain brush, paint thinner or something for those spots? Number 3 is that we notice very small bubbles here and there that we didnt notice before on the surface. The reason we didnt see them before is because our rigid plastic resin is transparent after curating. We do spray paint a white primer over it, however it still can be hard to see the small details. The color brings them out.
Here are the materials we use. If you recommend something else please let us know. We use Smooth-Cast simi rigid plastic for making the figurines. (We dont have access to a vacuum chamber) I try to sand down some of it before spraying but its hard to see and its hard to sand some spots. After sanding we use sandable primer from the brand PLastiKote as was recommended from the people at Smooth-Cast. We then use Acrylic paint for painting. By the brands Reeves and College. The figurines/magnets we make are around 3 x 3 inches. One is the Mask from Courage the Cowardly dog, another is a frame. (to give you and idea of the detail)
Hope you can help us. Thank you very much!

Cool Hand Luke... Yes, you can paint Alumilite! We recommend for Alumilite to use lacquers or acrylics but you may also use synthetics or enamels. A lacquer primer may be needed to assure the long term effectiveness of the paint. You may wish to paint your silicone mold before casting Alumilite. Paint the mold with a fast drying acrylic or clear coat. Once it is completely dry, cast your piece. When you demold the part you will pull out will be a painted piece. Alumilite will chemically bond to the dried paint. The other option is to paint the part as soon as it comes out of the mold while the resin is still curing to allow the curing resin to cross link with the paint.
Regards,
Carol

... I might add that you need to clean your castings prior to painting. Soak the castings for 30 minutes in warm soapy water, then wash them thoroughly under warm running water. If you soak the castings in water that's too hot, the resin might soften and warp. Common dish soap is good for this because it will easily remove the greasy mold release film from the castings caused by the casting process.... It's just a good idea to wash the parts just to make sure your paint will stick. If you don't wash the parts properly, paint will not stay on them.
Resin is impervious to most solvents and paint thinners. Just about any type of paint or primer, automotive, home, or hobby paint, either lacquer, enamel or acrylic, can be used on resin without fear of crazing the surface. I would use either white or grey primer on your figures.
I use either a 000 or 0000 detail brush for the small stuff.....check out the selection of brushes at your local hobby store, avoid the cheap brushes as your get what you pay for.....look for the brushes with the least amount of bristles/hair that come to fine point. I have also used tooth picks in some instances for detail work.

And plain old indoor/outdoor spray paint (with primer) will work too if you're just doing a primer coat and will be painting over top of the primer with other paint. Just be sure to hit it with the primer as soon as it's hard enough to demold or it might come off here and there - I have a casting that I was using as a test and sprayed it quite a while (a few days or so) after demolding and since it's part of my key chain, spots have rubbed off where it goes in and out of my pocket. I could repaint but it was a test and I'm fine with it as it is.
