It shouldn't be walked on or disturbed during the drying process, as doing so could cause a serious misalignment of the tiles you just laid, a problem that would be difficult to fix. This means you need to allow it to dry before grouting. Drying time depends on how you mixed the thinset, how much you put down before tiling, humidity and temperature.
Be sure to follow the manufacturer's instructions when mixing thinset. It shouldn't be soupy or runny, but it shouldn't be too stiff either. In some cases, as much as 72 hours is required. If the knock sounds hollow, the mortar is still wet beneath the tile. If the knock sounds solid, then your mortar has hardened.

Spread the mortar on a dry substrate. Heat the surrounding environment with a room heater, or direct the heat towards the mortar. Circulate the air around the mortar with a fan and keep the space ventilated to maximize air flow.
Use quick-setting polymer-enhanced mortar. Let the grout set for 15 to 30 minutes, and wipe up the excess grout with a dense grout sponge soaked in water. If you think it's going to take you longer than 30 minutes to grout all of the tiles and be ready to move onto cleanup, you may have to work in smaller sections.
Thinset mortar is an adhesive and binds the tile to the subfloor beneath. Simply so, how long should mortar dry?

The thinset under the tiles isn't receiving as much air as the edges and is therefor not fully cured.
Furthermore, how can I make mortar dry faster? Spread the mortar on a dry substrate. Heat the surrounding environment with a room heater, or direct the heat towards the mortar. Circulate the air around the mortar with a fan and keep the space ventilated to maximize air flow.
Use quick-setting polymer-enhanced mortar. The humidity, temperature and air flow in a room affect how long it takes to dry, but thinset generally is cured and ready to walk on or grout in 24 to 48 hours.
