Installation Guide
DESCRIPTION
Mapeguard 2 is a next-generation, flexible, thin, 40-mil (1-mm) lightweight,
load-bearing, fabric-reinforced “peel-and-stick” crack-isolation membrane.
After application, ceramic tile or stone can be installed immediately with any
polymer-modified cement-based mortar. Glue-down wood flooring can also be
installed with any MAPEI urethane adhesive.
Mapeguard 2 helps to prevent existing or future in-plane floor cracks (with
movement up to 3/8" [10 mm] wide) from transmitting through grout, ceramic tile
or natural stone. It also reduces the transmission of impact sound (footsteps,
dropped objects, etc.) and airborne sound (voice, TV, etc.) through floors when
installed under ceramic tile, stone or wood floor coverings.
FEATURES AND BENEFITS
• Dual protection – Provides crack isolation and sound reduction
• Lightweight – 35% lighter than previous generations of comparable
membranes
• Semi-rigid sheet – Easy to position on floor and cut to size
• Split-back release film – Installs faster than membranes with 1-piece liners
• White surface – Easy to view under lower-light conditions
• Thin-film adhesive backing – Bonds to a variety of substrates
• Time-saving – Prime, peel, stick and then install tile or wood immediately
• No odor – Great for confined spaces
• Contains post-industrial recycled material
INDUSTRY STANDARDS AND APPROVALS
• ASTM C627 (Robinson): See the“Product Performance Properties” section
for Mapeguard 2.
• ASTM E492-04 (Impact Sound), E90-04 (Airborne Sound), E2179 (Impact
Sound): See the “Product Performance Properties” section for Mapeguard 2.
• ANSI A118.12 (Crack Isolation For Tile & Stone): See the “Product
Performance Properties” section for Mapeguard 2. Mapeguard 2 exceeds
the high-performance standard for crack isolation.

WHERE TO USE
• Residential (homes, apartments and condominiums) and commercial
(airports, malls, office buildings, restaurants and galleries) floors, both
interior and exterior (with proper drainage)
• Ideal for multi-family or multi-story buildings to reduce noise transmission
through floors
LIMITATIONS
(for Mapeguard 2, MAPEI SM Primer
™
and MAPEI SM Primer Fast)
• Do not use over cracks or control joints subject to: out-of-plane movement;
or in-plane movement greater than 3/8" (10 mm). Note: See the “Expansion
Joints” section.
