I made a unimold of a plug today. The plug got bad and also the mold. Does anyone know what can have caused these problems? I have use both the pattern coat primer and the hi gloss on a MDF pattern.

The problem can be:
1. Temperature at your workplace (most separators needs >25 C temperature during application)
2. Mould coating - do not know this products, but many standards coats react with release agents. Mould coating has to be fully cured of course (some products needs even 14 days after coating for full curing.
3. Release agent itself.
