  • Approved for use with solid and engineered exotic and domestic wood flooring of any width and length; finger block parquet; acrylic impregnated wood and laminated plank; and reground rubber or cork underlayments
  • Approved for bonding plywood panels to concrete subfloors as required for nail-down or double-glue installation methods of the final flooring
  • Interior residential (rental apartments, condominiums and homes)
  • Interior commercial (office buildings, hotel rooms and hallways, and restaurant dining areas)
  • Interior heavy commercial (hotel lobbies, convention centers, airports and department stores)
  • Interior institutional (hospitals, schools, universities, libraries and government buildings)


  • Do not install over any substrates containing asbestos.
  • For interior installations only
  • Not recommended for flooring designed for nail-down installations only
  • Not recommended for prefinished cork flooring
  • Install flooring only in areas recommended by the wood-flooring manufacturer.
  • Do not apply over any adhesive residues, including cutback adhesive.
  • Do not install when the moisture vapor emission rate (MVER) exceeds 5 lbs. per 1,000 sq. ft. (2,27 kg per 92,9 m2) per 24 hours, when using the anhydrous calcium chloride test (ASTM F1869).
  • Do not install on below- or on-grade concrete if a functional vapor barrier is not present below the slab.
  • Do not install when the relative humidity (RH) of the concrete slab exceeds 80% (ASTM F2170).
  • Do not install in areas with known hydrostatic moisture problems.
  • Use only when the substrate temperature is between 50F and 90F (10C and 32C), and when the ambient relative humidity is between 20% and 80%.


  • Concrete (at least 28 days old)
  • Properly prepared cement terrazzo
  • Exterior-grade plywood and other approved wood substrates (per wood-flooring manufacturer recommendations)
  • Existing, properly prepared ceramic tile
  • Cement-based self-leveling underlayments and patching compounds
  • MAPEI epoxy moisture barriers
  • Properly prepared, primed gypsum underlayments that meet the requirements for compressive strength according to ASTM F2419
  • Radiant-heat systems that have been properly installed

Consult MAPEI's Technical Services Department for installation recommendations regarding substrates and conditions not listed.


  • All substrates must be structurally sound, dry, solid and stable.
  • The substrate should be clean and free of dust, dirt, oil, grease, paint, curing agents, concrete sealers, loosely bonded toppings, loose particles, and any other substance or condition that may prevent or reduce adhesion.
  • Substrates must be flat to 3/16" in a 10-ft. span (4,5 mm in a 3,05-m span).
  • Concrete and cement-based underlayments/patches must be cured and free of any hydrostatic and/or moisture problems.
  • See MAPEI's "Surface Preparation Requirements" document in the Reference & Installation Guides section of the Floor Covering Installation Systems page on MAPEI's Website.


Note: Utilize all appropriate personal safety equipment during product use. Refer to the Safety Data Sheet for more information.

  • Ready to use; no mixing is necessary.


Read all installation instructions thoroughly before installation. Refer to the wood-flooring manufacturer's guidelines for acclimation requirements and complete installation instructions.

  1. Select the appropriately notched trowel (see the "Approximate Coverage" section) and spread the adhesive evenly over the subfloor, keeping the trowel at a 45 angle to the subfloor.
  2. Only apply as much as can be installed within 45 minutes.
  3. Install wood flooring in strict accordance with the wood-flooring manufacturer's written instructions.


  • Ultrabond ECO 980 is extremely difficult to remove when cured. Immediately clean any adhesive smudges from tools and the flooring material's surface with Ultrabond Urethane Cleanerwhile the adhesive is still fresh/wet.


  • Protect from light traffic for at least 12 hours. Protect from heavy traffic for at least 24 hours.
  • Building owners should become aware of the woodflooring manufacturer's guidelines for climate-control settings (temperature and humidity). These conditions must be monitored and kept constant to ensure the overall performance and long-term success of the installation.

* Flash time is the recommended amount of time for a freshly applied adhesive to remain exposed to the air before the installation of floor covering.

** Working time is the maximum amount of time that an adhesive can remain exposed to the air and still effectively bond to the floor covering.

*** Adjustability time is the window of time during which the floor covering can be repositioned without compromising the bond of the adhesive.

Note: Working time may vary based on temperature, humidity, substrate porosity, trowel size and jobsite conditions.
