What happens if too much hardener is added to filler?

Hardener controls when and how fast the filler cures. Adding more hardener than recommended makes the chemical reaction start and proceed too quickly, causing a rapid exotherm. The result is a film that sets up fast, often becoming hard and brittle rather than flexible or soft. You can also lose working time and end up with internal stresses that lead to cracking. So, the best description is that it may cure too quickly and become brittle. The other descriptions don’t match how excess hardener changes the curing chemistry.
