Grace Vycor
®
Self-Adhered Flashings (Grace Vycor Plus, Grace
Vycor V40 and Grace Vycor Deck Protector) are to be applied
directly to a clean and dry surface. Some suitable substrates
include wood, pressure-treated wood, plywood, wood composi-
tion, oriented strand board (OSB), metal, vinyl, concrete, masonry
and gypsum sheathing. For additional information, refer to product
literature and Technical Letter 1, “Chemical Compatibility
with Other Building Materials,” located on our web site at
www.graceconstruction.com.
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, also prime wood composition and gypsum
sheathing with Perm-A-Barrier WB Primer. The coverage rate for
Perm-A-Barrier WB Primer is 6-8 m
