Integrating R-GUARD with other air barrier
and moisture protection components
Coordinate installation of connecting air barrier with other
trades to achieve a continuous air barrier assembly.
Coordinate installation of flashing and other moisture
protection components to achieve complete moisture
protection which drains liquid water to the exterior of the wall
assembly.
Some flashing components such as window and door head
flashing, pan flashing, roof sidewall step flashing, etc. require
a splice strip of R-GUARD Tape, Fill and Spray Wrap to
create a shingle lap which sheds water onto the face of the
flashing, not behind the flashing. Use R-GUARD as the
splice strip to create a seamless transition.
Alternatively, shingle lap with a suitable self-adhering transition
membrane such as SBS modified bitumen, or sheet membrane
flashing adhered and fastened with termination bars and
fasteners.
Use only water-based primers and neutral-cure sealants. Do
not use solvent or petroleum based primers or adhesives.
Preparation:
Fill any voids or gaps greater than 1/8” with a low expansion urethane
foam. Shave off the cured foam flush to the sheathed surface.
Remove any surface contaminants which may compromise adhesion of
the R-GUARD.
Do not use R-GUARD over fire retardant or pressure-treated wood
surfaces.
Installing PROSOCO R-GUARD ® Tape:
R-GUARD Tape is a self-adhering, reinforcing mesh tape designed
for use with R-GUARD Fill and R-GUARD Spray Wrap. Install
R-GUARD Tape in a shingling manner to promote positive drainage
of bulk water.
Use a seam roller or blunt tool to press and firmly adhere R-GUARD
Tape to the sheathing. Round sharp corners of all installation tools to
reduce a potential for damage or tearing.
When multiple strips of R-GUARD Tape are required, create a
minimum 2.5” (64mm) lap to insure continuity of the reinforcing
mesh tape.
