R703.12

Section R703.12 is titled 'Adhered masonry veneer installation' and covers the requirements for attaching thin masonry units to the outside of exterior walls with an adhesive material. A cross-reference to 2 sections in this code, 2 standards, and the manufacturer's installation instruction for compliance and installation of adhered masonry veneer is established. The purpose of this section is to prevent adhered masonry veneer from detaching from the wall framing and premature degradation from water intrusion through exterior walls into a building.

The model shows a section of stone veneer being set into a mortar base.
