V40
Self-adhered ashing for critical non-roof
detail areas
Product Advantages
• Premium protection against air, water and
moisture inltration
• Highly conformable
• Protects critical non-roof detail areas including masonry
walls and stucco
Moisture control is the rst step to
mold control.
Water from both exterior and interior sources is among the
worst enemies of building structures. When water enters the
wall system and remains there for a long time, it creates an
environment favorable for the development of rot, mold and
mildew. Proper waterproong and ashing practices are needed
to ensure high quality, long-lasting construction.
Repairs resulting from water and moisture
inltration are major concerns for homebuilders, contractors,
architects and homeowners as they are difcult repairs and
extremely costly. Window and door openings, deck-to-wall
intersections, foundation sill plates, corners and other penetration
areas are the most common water entry points. The solution—a
self-adhered ashing membrane properly integrated with the
other elements of the building structure. This will create a barrier
to water entry as well as a drainage plane for water to drain out of
the wall.

V40, a high performance, self-adhered ashing
membrane provides premium protection against water inltration
in all critical non-roof detail areas, which traditional building
papers, felts and housewraps cannot match.
When properly installed, Grace Vycor V40 can reduce the risk of
water inltration, often associated with costly call-backs.
Grace Vycor V40 fully adheres to the substrate, seals around
fasteners and prevents water from passing through and into the
structure. It is highly conformable, easy to detail and provides
premium protection against leaks. Best of all, Grace Vycor V40
employs the same proven technology as our famous Grace Ice &
Water Shield
®
—the market leader for over thirty years.
