Ulracal30 Usage Help...

[🪦 Jason-V ●]

Ive never made a mold from this.. only used Hydrocal. I understand that Hcal sets faster, so you can make the mold usually in one go. However, my Hcal molds become very brittle around the detail in my masks, when i pull the blank out i lose detail.. every time. Im gonna try Ucal30, but never worked with it. So my question is the best way to make a pro mold off my master copy. I guess start with a thin layer for the detail layer. How long before i start addind additional layers??? And how much build up?

Thanks for any HElp!
