Most manufacturers stock a primer for use with their adhered flashing that has first been applied to the wall.
PROBLEM AREAS
Where the flashing extends through the face shell of the veneer, it should be turned down to form a drip to ensure that moisture is flashed outward and down. When flashing is stopped short of the face shell, a potential portal for moisture to seep underneath the flashing is created (see Figure 5).
Depending on the type of flashing material, extending the flashing through the veneer may not be possible. For instance, rubberized flashing deteriorates when exposed to UV rays from the sun, so it must be stopped one-half inch back from the face shell of the veneer. Plastic flashings can also be adversely affected by the sun and probably should not be exposed. One way to overcome this problem is to use a stainless steel drip edge flashing ranging in depth from 1-1/2 inch to the full depth to reach the face of the substrate. This highly corrosion resistant flashing sits on top of the shelf angle or footer and extends through the face of the veneer where it turns down to form a drip. The rubberized or plastic flashing is then adhered to the edge flashing and a through-wall flashing installation is accomplished (see Figure 6). This is an extremely effective flashing method that allows for the combination of stainless steel with economical rubberized flashing. Plastic flashings
