Can mortar drying too quickly?
If left under the hot summer sun, thin set mortar will set up too fast – as if you had mixed it with warm water. Direct sunlight on hot, dry days can cause mortar to lose its moisture to the atmosphere. This weakens the mortar and might not allow it to hold up over time.

Exact Answer: 36 Hours
Mortar is a blend of sand, cement, and water. It’s used to make bricks stick together. Mortar dries out by absorbing water from the air over time, and it takes about three days for the mortar to dry enough for use on brick walls. Once the mortar has dried, one should seal it with an exterior sealant.
Why Would Drying Mortar Take So Long?
For a seal to take place, the mortar needs to be set for at least 36 hours. In other words, it needs time for water from among other sources to evaporate from the dry mix and will remain sticky until then.
Conclusion
To complete the mortar work properly, a mason worker needs to take care of a few things. Firstly, it is better to wet the bricks before putting the mortar on, and this way, the mortar can set slowly and absorb the moisture of bricks.
How long does it take for thinset mortar to cure?

What are the factors that affect the cure time of mortar?
There are a few key environmental variables that affect your mortar cure time. Ambient temperature, air flow, the amount of water used in your mix, and humidity all affect mortar curing time.
What is type S mortar?
Type S mortar is a medium strength mortar that cures to a minimum compressive strength of 1800 psi. It is typically used on exterior walls, patios, paving, and other projects where mortar comes in direct contact with the ground.
Why do you need to add moisture to mortar?
That means that even the moisture in the air itself needs monitoring. If you are building under extremely low humidity, you may need to add more moisture your mortar to assist in the curing process.
What is the lowest strength mortar?
Type K is the lowest strength mortar available and has a very limited purpose. It only cures to a minimum strength of 75 psi so it is primarily used for historical preservation. It is not used for anything structural or load bearing due to its low cure strength.
How long does it take for grout to set?
After 24-48 hours, depending upon the humidity and ambient temperature, you can begin applying grout.
What is the strength of type M mortar?
Type M mortar cures to a minimum strength of 2500 psi and is the strongest type of mortar. It is used for projects that need to withstand extreme gravitational forces and hold large lateral loads.
Does mortar crack under heat?
Mortar joints also crack from expansion during use and contraction after every fire. Excessive heat results from building a fire that is too big for the firebox. Too much heat wears out the firebrick and the mortar, causes cracks and other damage, and is generally an unsafe practice.
What is the best fireplace mortar?

Use this cement anywhere a quality high-temperature adhesive is required for furnaces, firebrick repair, filling gaps, sealing joints, or gluing ceramic logs. Adheres to metal, stone, and firebricks, creating a permanent smoke- and gas-tight seal.
What temperature is too hot for mortar?
Ideal temperatures for mortar are between 60 °F and 80 °F (15.6 °C and 26.7 °C). Mortar temperatures over 120 °F (48.9 °C) may lead to flash setting, resulting in lower compressive strength and reduced bond strength. Thus, do not heat sand or water above 140 °F (60.0 °C).
Is it normal for mortar to crack?
Although masonry can deform elastically over long periods of time to accommodate small amounts of movement, large movements normally cause cracking. Cracks may appear along the mortar joints or through the masonry units.
