Installation requirements vary with substrate type. You may be able to view the substrate by looking up from the underside of the veneer using a small mirror, or you may be limited to looking for deficiencies.
On exterior stud walls, weep screeds and other base flashings should be held a minimum of 4 inches (102 mm) above grade or a minimum of 2 inches (51 mm) above paved surfaces such as driveways, patios, etc. This minimum can be reduced to 1 /2 inch (13 mm) if the paved surface is a walking surface supported by the same foundation supporting the wall.
On exterior stud walls where the AMSV continues down a concrete or CMU foundation wall, and where a weep screed is incorporated into the wall-to-foundation transition, at the bottom maintain minimum 2 inches (51 mm) clearance from grade, or 1 /2 inches (13 mm) clearance from a paved surface.
On exterior stud walls where the AMSV continues down a CMU foundation wall, with WRB and lath installed down to the weep screed at bottom, maintain a minimum 4 inches (102 mm) clearance from grade, or 2 inches (51 mm) clearance from a paved surface.
Where AMSV is applied over an exterior concrete or CMU wall, maintain 2 inches (51 mm) clearance from grade or 1 /2 inches (13 mm) from a paved surface. • Over an exterior concrete or CMU wall that is not enclosing conditioned space (e.g. landscape walls, pillars, columns, etc) maintain a minimum 2 inches (51 mm) clearance from grade or 1 /2 inches (13 mm) clearance from a paved surface
MSV should not be directly exposed to discharge from downspouts or landscape irrigation sprinkler heads.
