How do I repair a torn latex mold?

The best method we found is to lightly abrate the area, and clean the area with acetone or alcohol. Then brush some UreCoat™ from Smooth-On on the tear, take some gauze or other stretch fabric and push into the wet UreCoat™ then encapsulate fully in UreCoat™. This will create a strong flexible repair to the original latex.
