Mortar drying time depends on environmental conditions, mortar composition, and application thickness. Warmer temperatures and lower humidity levels accelerate drying, while cooler temperatures and higher humidity slow it down. Cement-based mortars dry faster than lime-based ones. Thicker layers require more time to dry. Typically, the mortar will dry to the touch within 24 to 48 hours, but complete drying and maximum strength may take weeks. Proper curing is crucial for durability. Protecting the mortar from rapid evaporation aids in optimal drying. By considering these factors, builders can ensure successful construction projects.
