MAPEI® Ultrabond ECO 711™ Vinyl Tile Adhesive - #A4621

Availability:

• Sizes: 1 gallon and 4 gallon containers

Construction Details:

• Premium clear thin-spread VCT adhesive
• For installation of vinyl composition tile (VCT) in residential, commercial, and institutional applications
• Low odor - can be used in occupied buildings
• Quick-drying
• Superior grab and slip resistance
• Ready to use - no mixing required
• High moisture resistance - for moisture vapor emissions rates (MVERs) up to 8 lbs.
• CRI Green Label Plus certified #GLP84381
• RFCI IP #2 Recommended Installation Practice for Vinyl Composition Tile (VCT)
• Suitable for use over fresh concrete slabs with diminishing moisture vapor emissions rates (MVERs) up to 8 lbs. per 1,000 sq.ft. per 24 hours and relative humidity of concrete slabs do not exceed 95% (ASTM F2170). Apply trowel or roller
• May help contribute to LEED certification of projects, see product data sheet below for more details. Do not install over any substrate containing asbestos.
• For interior use only
• After installation protect the floor from light traffic for at least 24 hours and heavy traffic for at least 48 hours
• Use only when the substrate temperature is between 50?F and 90?F (10?C and 32?C) and the ambient relative humidity is below 65%.
• All substrates must be structurally sound, solid, stable and dry
• Suitable Substrates: exterior grade plywood (Group 1, CC type); approved wood underlayment (see manufacturer details); concrete and properly prepared cement terrazzo; cement-based self-leveling underlayments and patching compounds; embossing levelers applied over existing properly prepared and fully bonded ceramic tile and sheet vinyl; single layer and properly prepared fully bonded vinyl composition tile (VCT); primed and properly prepared gypsum underlayments that meet the requirements for compressive strength per ASTM F2419
• Before installation substrates must be clean and free of dust, dirt, oil, grease, paint, curing agents, concrete sealers, loose bonded toppings, loose particles, old adhesive residue, and any other substance or condition that may prevent or reduce adhesion.
• All surfaces must be level, even, flat and smooth prior to installation.
• Concrete and cement-based underlayments and patches must be fully cured and free of hydrostatic and moisture problems.
• Use anhydrous calcium chloride tests to determine MVERs according to ASTM F1869
• Concrete slabs that exceed 8 lbs in MVER should be treated with a moisture vapor reduction. See Technical Data Sheet for more information.
