What is an important characteristic of adhered masonry veneer installation?

An important characteristic of adhered masonry veneer installation is that it should maintain clearance from grade or roof. This clearance is crucial for several reasons, primarily related to moisture management and preventing potential damage to the building structure. By keeping the adhered veneer above grade or roof surfaces, you reduce the risk of water intrusion and the associated issues of mold, rot, and degradation of the exterior materials.

This practice helps ensure that the base of the veneer does not come in direct contact with soil, which can retain moisture, or with roof surfaces, which may also be prone to water accumulation. Adequate clearance helps promote proper drainage and ventilation, which are essential in maintaining the longevity and performance of the adhered masonry system.

While other options may contain relevant information about materials and installation techniques, they do not address this critical aspect of preventing water-related issues, making the importance of maintaining clearance a key characteristic of adhered masonry veneer installation.
