| Can I add more hardener to epoxy to make it cure faster?
On Page 3 of Product Bulletin Premium Marine Grade Epoxy the section on Mixing will answer this question. It is important that only the recommended mixing ratio be used, too much or too little hardener will produce inferior results. Never thin epoxy with solvents. Be sure to mix thoroughly, as incomplete mixing will produce an incomplete cure. Mix vigorously for two (2) minutes.
