1.

Apply FastFlash a minimum of 12 mils to the sill, extend 4" below the sill on the sheathing, and up at least 2" of each jamb. All fasteners into and around the rough opening should be driven flush to the substrate. Apply FastFlash to any proud or over-driven fasteners. Apply FastFlash to each inside corner and any joints within the RO. For FastFlash Gun Grade use a dry joint knife, trowel or chip brush to spread the wet product to create a seamless flashing membrane which protects the sill, extends 2" up each jamb and 4" inches over the face of the structural wall. Apply additional FastFlash as needed to create an opaque, monolithic flashing membrane free of voids and pinholes. Voids in the rough opening may require FastFlash or Joint & Seam Filler to bridge prior to or post application of field membrane into rough opening.

2.

Apply the selected R-Guard field membrane over the prepared sheathing and into the rough opening jambs and header, overlapping the FastFlash at least 1".
