After the self-adhering membrane backup flashing was installed, the metal through-wall flashing was installed over it (seen here on an adjacent roof).
The exposed face of coated copper flashing was protected with blue tape, then the water management layers were installed on the wall.
After the self-adhering housewrap and 30-lb. asphalt felt paper are applied, a drainage matrix (with gray-colored filter fabric) is installed. Here, Obdyke Slicker Max drainage matrix is used, though on similar masonry veneer projects, the author also uses Mortairvent. The stone veneer is re-installed, secured with stainless steel masonry anchors.
Self-spaced corrugated plastic weeps provide enhanced draining. The mortar is mixed up dry on site similar to the original mortar.
A mason puts the finishing touches on the reinstalled stone veneer, cleaning up the mortar around the corrugated weeps.
