If you cast Latex into Ultracal, can you later seal the ultracal and cast silicone into it?

I'm going to say a theoretical yes....but that is going to be a lot of sealer and a little dicey

Not sure why you would need to seal the ultrarocal to cast silicone. But, once you cast silicone, the mold may not be suitable for latex.
