Using casting materials as "Paint"

[CabinetMaker]

I was working on a laser blank from Constant when I had an idea. The horse blank is limited to a black horse. I was wondering if it is possible to take casting resins and mix them with different colors and use that to fill in the laser cutout with it. The trick would be to use it like paint so that one could match the colors of a particular horse. Paint horses come to mind but dapples and buckskins could also be interesting.

I would want the color to go the full depth so that as the blank is turned down the colors remain true.

I am concerned about bubbles and open time for working in the differ colors.

So to all have have worked with casting (I have not),is something like this possible?

The easy way to do that is to thicken PR with fumed silica and tint it with opaque pigments. You can essentially make a paste thick enough to spread with a knife. That is how professional fiberglass workers fill non-structural voids.

I hope that helps,

Does some place like Hobby Lobby or Michael's have the stuff needed to experiment with this?

You could also try tinting/coloring 2 part epoxy and using that to fill in. Probably a lot cheaper and easier to find.

If the craft stores don't have it, you can get colloidal silica at West Marine.

+1 on Epoxy instead. Much easier for such a small amount.

You could also use any Hobby paints to tint your epoxy. Remember to write down any amounts you mix so that you can repeat the color later on. Jim S
