Pr cure time w/ acrylic paint

[Daddy1]

I just started casting. I was going along fine. I did some clear cast which hardened great and quick. I did some with powder dyes and the same result except the last one came out rubbery. I then tried with acrylic paint and has been 24 hours and it is sticky and rubbery.
Could it be the temp? I do it in the basement and it is about 65 degrees. Could it be the paint? I used 7 drops/oz of hardener as my instructions stated.
Any suggestions?

I have had the same problem with acrylic paint. It will dry, but takes a long time.

As mentioned, given enough time, they will harden. Some acrylic paints aren't totally compatible with the PR. I tried using some once, just to have it clump together as the PR cured. When looking at the whole blank, it looked fine. But when turned to the thinness that many of the pens calls for, you could see clear PR and clumps of the colorant. I gave those paints away and now just stick with colorants specifically for PR. I hope yours turn out better.
