Little trouble with Aves Apoxie Sculpt... Doesnt dry.

Posted in Custom Workstation

So I sculpted a part on a figure, days later I accidentally broke part of it off. When tryin to repair it, the apoxie doesn't wanna dry, it stays some what hard in the center, and sticky on the outside. I know its not the way I mixed it because I made extra to use on other figures, and they dried perfectly.

Could it be that im using the dried apoxie with the new wet stuff? It still sticks just doesn't dry. I let it sit for 2 days and still no change.
