Lastly, let the mortar sit for 10 minutes before using it. This is referred to as slaking and it gives the additives enough time to become activated. It also ensures all the powder is sufficiently moist. Once 10 minutes has passed, give it one last stir and your thinset mortar is ready to go.

Similarly, you may ask, how long do you have to work with mortar?

Cement bags that are opened tend to absorb environmental humidity, thus changing the water percentage of the mortar mix. Mortar is good for 90 minutes. After that time, discard the mortar because it starts to lose some of its characteristics.

Furthermore, does thinset mortar go bad? Normal thinsets can go bad from drawing moisture. If sealed in the plastic bags like Mapei's they should last quite a while.

Likewise, how long can you use thinset after mixing?

The instructions clearly give a max pot life of 3 hours, saying that power remixing may be needed if the mortar starts to harden.
