It shares the same 20–30 minute set window, which is advantageous for time-sensitive jobs. It’s also suitable for crafts like casting and sculpting. Best for owners who anticipate multiple applications, but avoid if you need ultra-rapid setting for a single tiny repair.

Mixing ratio and set times are clearly outlined: about 3–4 minutes setting, finished hard in about 30 minutes. It’s ideal for intricate molds, dioramas, and sculpture projects.
