An Adhered Masonry Veneer system (AMV) is defined as “masonry veneer of natural or manufactured stone, secured to and supported by the backing through adhesion” and are sometimes called “lick and stick” systems. The more typical masonry brick veneer system has a drainage cavity behind and the veneer is supported on itself and anchored with metal ties. Exterior AMV wall components can vary, but they are similar to a stucco system with a weather resistive barrier, scratch coat with embedded wire lath, and a finish coat of adhesive mortar.
The design and installations of AMV can be challenging since relevant building codes and industry standards are not well known or understood, and the system relies heavily on workmanship and selecting the right materials. This is particularly true when choosing a manufactured stone rather than costlier natural stone, and when used in freeze-thaw climates.
