s-333 medium pour-a-mold question

[Ed]

I recently poured a vertical mold in a tubular form using s-333 medium pour-a-mold.The initial pour came up a bit short of the amount I wanted to cover my model so I made a second pour about the same time the first pour started to kick. The result was the scecond pour did not hardened even with an extra day of drying. I have removed the second pour from the top of the mold. In so doing I have created a pretty tacky mess,even down some of the side areas. My question is do I need to make a third pour in hopes that this one will harden or is there an easier way to solidify all surface areas?Thanks in advance. Ed
