Mapelastic AquaDefense 1 Gallon

DESCRIPTION
Mapelastic AquaDefense is a premixed, advanced liquid-rubber, extremely
quick-drying waterproofing and crack-isolation membrane for installation under
ceramic tile or stone in residential, commercial and industrial environments.
Mapelastic AquaDefense provides a thin, continuous barrier to protect adjacent
rooms and floors below from water damage. For common problem areas like
coves, corners, cracks and drains, it can be combined with MAPEI’s optional
Reinforcing Fabric or Mapeband™ accessories (cove roll and drain flash) to
provide additional protection. Mapelastic AquaDefense dries after about 30 to
50 minutes and is then ready to receive any MAPEI polymer or epoxy mortar.
Mapelastic AquaDefense can be flood-tested after 12 hours of drying time,
is IAPMO-listed for use as a shower-pan liner, and exceeds ANSI A118.10
and ANSI A118.12 standards.
FEATURES AND BENEFITS
• Very quick drying: Install tile after 30 to 50 minutes of drying time.
• Time-saving: Flood-test as shower-pan liner after 12 hours of drying time.
• Apply with roller or brush – easy to install over flat, curved or irregular
surfaces
• Bonds to a wide range of surfaces; convenient, user-friendly and versatile
• No odor; great for confined spaces
• Prevents in-plane floor cracks from transmitting through tile or stone

WHERE TO USE
• Residential and commercial interior/exterior floors, walls and ceilings
• Industrial interior floors and walls
• Tub and shower surrounds: Bathrooms; kitchens; food prep, dishwashing,
servery and cafeteria areas; countertops; and laundry rooms
• Residential and commercial submerged applications: Freshwater pools,
fountains and water features (completely covered by ceramic tile)
• Cantilevered balconies and decks over unoccupied space (see the
“Limitations” section below)
• Balconies and decks over occupied space when used in conjunction with
a primary waterproofing membrane
• Steam rooms and steam showers (refer to TCNA handbook’s sections
SR613 and SR614, or TTMAC 319SR and 321SR)
• Meets ASTM E96 Procedure E for a low-perm waterproof membrane
• In-plane crack isolation up to 1/8" (3 mm) over nonstructural cracks
• MAPEI's Reinforcing Fabric is available but optional for use on coves,
corners and field application.

LIMITATIONS
• Mapelastic AquaDefense is not for use over structural
cracks, in-plane cracks beyond 1/8" (3 mm) or where
vertical out-of-plane movement occurs.
• Do not use over substrates containing asbestos,
dimensionally unstable substrates such as hardwood
flooring, particleboard, oriented strand board (OSB),
Masonite or metal. See "Suitable Substrates" section
below.
• Do not use over: Plank flooring, treated plywood,
Lauan, gypsum-based floor-patching compounds,
vinyl, glazed tile, laminate, fiberglass or epoxy floors,
or storage tanks.
• Do not use where excessive substrate moisture and/or
where negative hydrostatic pressure exists. Maximum
allowable moisture is 8 lbs. per 1,000 sq. ft. (3.63 kg per
92.9 m2
) per 24 hours per ASTM F1869 or up to 85%
relative humidity as measured with moisture probes.
• Do not use: As a single-application roof-deck membrane,
wear surface or primary waterproofing membrane on
balconies or decks directly over occupied space or in
storage tanks; or with premixed setting materials.
• Do not allow direct contact with solvent-based materials
