Mortar drying time is influenced by environmental conditions, mortar composition, and application thickness. Higher temperatures and lower humidity levels speed up drying, while cooler temperatures and higher humidity slow it down. Cement-based mortars dry faster than lime-based ones. Thicker layers take longer to dry. Typically, the mortar will dry to the touch within 24 to 48 hours. However, complete drying and achieving maximum strength can take weeks. Proper curing is essential for durability. Protecting the mortar from rapid evaporation promotes optimal drying.
