In Conclusion:
After 30 minutes, the No. 2 sample with the standard amount of hardener is completely ready for subsequent polishing and cutting processes.
The No. 1 sample with little hardener amount has not been hardened yet. Even though ，the curing time of Sample No. 3 with extra hardener amount is short， it is not strong enough.
Therefore， if you choose to use hardener to your sintered stone adhesive, we suggest to use the standard amount 1%-2%(summer) and 2%-3%(winter) , and make sure stir the hardener and adhesive thoroughly.
