My first attempts at casting several months ago were not that great, so now I'm seeking some advice. I'm going to take another stab at it, and I'd like to use some acrylic craft paint that I've got laying around. I'm going to be casting PR. My plan is to use two different colors swirled together. Can I use this paint as the dye? How much (or little) should I use? Should I mix each color separately and then swirl them together?

Mix them seperately. Then mix the hardener and let them start to gel before you pour them together. This will keep them seperated the most. If you pour too early, they will just mix and make a new color.

The amount depends on how opaque you want the blanks. You will be able to tell how much as you mix in the paint. I use drops off of a popsicle stick to get the mixture color I want.
 
Ok, I tried it on Wednesday and I think I used WAY too much paint. The resin still hasn't set completely. It's mostly cured but tacky on top. I just tried a single color as an experiment and only mixed enough resin for one blank. So my conclusion is that I can use acrylic paint, but maybe only a couple of drops?:confused: Anybody have any success with this pigment? Or should I cut my losses and move on?
 
I started with the paints many years ago and they work fine. Don't overload with the paint. They will be tacky on the surface, but it turns off. I can tell when the blanks are ready by the sound when tapping them together.
 
I only use a couple of drops of paint in mine. It depends on how opaque you want the blanks but only a couple of drops at a time so that you don't add too much.

Like Dozer said, your blanks will stay tacky on top for a long time. You can post cure them with 170 degree oven or put them under a dedicated light and the tackyness will go away.

Don't give up!! The enjoyment and satisfaction once you get it down is well worth the learning curve!!!
