If you add water to stiff thinset to make it workable, you break the microscopic Portland cement crystals and the thinset will NOT be as strong as it could be. This is why you only mix as much as you can use in a short time.

Besides, how much water do you add to Thinset?

Water Mixing Ratio Thinset is available in powder form in both 25- and 50-lb. bags. The ratio of water to mortar for thinset tile is 6:50 or 6 qts. of water per 50-lb.

It takes a very long time to cure.

Can you rewet Thinset?

There is no way to save mixed thinset. Thinset cointains portland cement, which chemically reacts with the water you add to harden. It does not dry by evaporation, so if you mix up a batch of thinset and pack it in an air-tight container, it will still harden in a few hours.

But that's way too much thinset to use at once, so I decided to just start with 1 quart of water, which is about one fifth of the bag, which is an easily manageable amount.

How do you know when thinset is dry?

You may notice that the edges of the thinset or the thinset showing through the grout lines looks dry. Don't be fooled by this. The thinset under the tiles isn't receiving as much air as the edges and is therefor not fully cured.
