Curing of mortar is essential for achieving optimal strength and durability, and maintaining proper moisture during the initial curing period is a critical factor. This process allows chemical hydration to occur, as the water content in the mortar is necessary for the cement to bond with the aggregates and develop strength.

Maintaining moisture for several days ensures that the mortar does not dry out too quickly. If the mortar dries before it has fully hydrated, it can lead to cracking and reduced overall strength, potentially compromising the integrity of the masonry.

While temperature, humidity levels, and wind exposure are important environmental factors that can influence the curing process, the direct action of ensuring adequate moisture levels in the mortar is what most significantly impacts the curing effectiveness. Keeping the mortar damp aids in keeping the hydration process ongoing, which is fundamental for proper curing.
