Precautions & Limitations
Vycor Plus self-adhered flashing is designed for critical NON-ROOF flashing details. The membrane is
slippery—DO NOT install on the roof; DO NOT walk on the membrane.
Do not leave the product permanently exposed to sunlight. Maximum recommended exposure time is 30
days. Due to its slight asphaltic odor, apply this product where the membrane is not exposed to interior living
space. Vycor Plus flashing should not be used in hot desert areas in the southwestern United States.
Vycor Plus flashing is not compatible with flexible PVC. Contact window manufacturer for specific
application instructions required when using a bituminous-based flashing. Certain metal window applications
with integral nail fin may have specific limitations.
Some solvents in certain caulking may be incompatible with the adhesive in Vycor Plus flashing.
For more information, check with your local GCP Applied Technologies technical sales representative.
Application Instructions
Surface Preparation
Apply Vycor Plus flashing in fair weather when the air, surface and membrane are at temperatures of 25°F
(-4°C) or higher. After precipitation, allow a minimum of 24 hours for drying before installing the flashing.
Install directly onto a clean and dry surface. Some compatible substrates include wood, plywood, oriented
strand board, metal, concrete and masonry. Remove dust, dirt, and loose nails. Protrusions must be removed.
Surfaces shall have no voids, damaged, or unsupported areas. Repair surfaces before installing the
membrane.
Priming is generally not required for most substrates provided they are clean and dry. However, on concrete,
masonry and DensGlass Gold , apply Perm-A-Barrier WB Primer. If adhesion is found to be marginal,
prime wood composition and gypsum sheathing also with Perm-A-Barrier WB Primer. The coverage rate
for Perm-A-Barrier WB Primer is 250–350 ft /gal (6–8 m /L). Allow primer to dry completely,
approximately 1 hour depending on weather conditions, before application of flashing.
Membrane Installation
Using the 6 in. (150 mm) and 12 in. (300 mm) measurement markings, cut the membrane to the desired
length. Peel back the release paper to expose the adhesive. Align the membrane and press into place with
heavy hand pressure.
