Rubberized Asphalt Flashing Membrane
Description
Rubberized Asphalt Flashing Membrane is a flexible 40 mil self-adhering sheet
membrane consisting of a self-adhering rubberized asphalt, a removable treated
release film and a high density 8-mil polymer film as the top surface. The Rubberized Asphalt Flashing Membrane features an integrated 90% open-mesh drainage
mat with weep tabs factory-bonded to the material, eliminating the need for separate mortar collection devices and weep vents.
Uses
Rubberized Asphalt Flashing Membrane is an in-wall flashing membrane for use
with concrete, masonry, exterior, gypsum sheathing, felt-faced and foil-faced
polyisocyanurate foam insulation, OSB or wood wall construction.

Advantages
• Excellent tensile, elongation, and permeance characteristics.
• The rubberized asphalt sheet has high adhesive quality.
• Treated release film for easier installation.
• Puncture resistant, non-removable surface film.
• Sheet available in 12”, 18”, and 24” widths (30.5, 45.7 & 61 cm).
• High temp resistance up to 245°F (118°C).
• Features an integrated 90% open-mesh drainage mat with weep tabs factory- bonded to the material, eliminating the need for separate mortar collection
devices and weep vents.
Limitations
• Rubberized Asphalt Flashing Membrane cannot be left exposed to sunlight
longer than 60 days.
• Do not install when temperatures are below 40°F (4°C).
• Membrane should not be brought into contact with products containing
coal-tar pitch.

Application Instructions
Surface Preparation
Masonry surfaces must be dry and have a smooth (not broomed) finish and be free of form release agents, voids and sharp protrusions.
Holes or voids must be repaired with non-shrink grout. Mortar joints must be flush to the face of concrete block and have a thorough parge
coat.
Cracks greater than 1/16” (1.6 mm) in width must be cut out to a minimum width of 1/4” (6.4 mm) with a minimum depth of 1/4” (6.4 mm),
and sealed using polyurethane sealant prior to installation of Rubberized Asphalt Flashing Membrane.
For wood, OSB, or gypsum sheathing surfaces; care must be taken to be sure that the surface is smooth, clean, and dry.
Priming
Priming is generally not required for most substrates provided they are clean and dry. However, on concrete, masonry, DensGlass® and
Dens Glass Gold® as well as any additional surfaces where adhesion is found to be marginal, prime the surface receiving flashing with
the appropriate primer and according to primer application instructions for specified weather conditions. Quick Dry Primer on EPS / XPS or
ICF surfaces.
Membrane Protection
All membrane material must be covered as soon as practical and in no case exceed 60 days.
** WARNINGS AND HAZARDS
Primers may contain combustible solvents. Avoid exposure to sparks, open flame, heat, and other forms of ignition. Use in well ventilated
areas. Avoid breathing vapors. Refer to MSDS for detailed product information and warnings.
CAUTION: The National Institute for Occupational Safety and Health (NIOSH) has concluded that fumes of
heated asphalt are a potential occupational carcinogen. Do not burn this product.
