Mapei Eco 975


Ultrabond ECO 975 capitalizes on MAPEI's Ultralite TechnologyT to provide a lightweight, 100%-solids, one-component moisture-cured urethane adhesive specifically designed for the installation of engineered wood flooring. Ultrabond ECO 975 reduces the pail weight by approximately 33% and yet provides similar coverage when compared with traditional urethane products. Ultrabond ECO 975 is easier to trowel, has excellent trowel-ridge hold, provides quick grab and offers excellent final bond strength.


•    Approved for use with parquet; acrylic impregnated wood and laminated plank; cork underlayment and all sizes of engineered wood flooring

•    Lightweight formulation technology for easy transport and installation

•    Utilizes rapidly renewable raw materials

•    Easy to trowel with excellent trowel-ridge holdout for proper adhesive bonding

•    100%-solids formulation; no solvent added

•    Extremely low-odor formula with negligible volatile organic compound (VOC) content

•    Also approved for use with ceramic tile and stone for mixed media installations with wood flooring

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.

•    Substrate should be clean and free of dust, dirt, oil, grease, paint, curing agents, concrete sealers, loosely bonded toppings, loose particles, old adhesive residues, and any other substance or condition that may prevent or reduce adhesion.

•    Substrates must be flat to 3/16" in a 10-foot span (4,5 mm in a 3,05-meter span). Refer to wood-flooring manufacturer's guidelines.

•    Concrete and cement-based underlayments and patches must be fully cured and free of any hydrostatic and/or moisture problems.

•    Use anhydrous calcium chloride tests to determine moisture vapor emission rates (MVERs) according to ASTM F1869 or use moisture probe tests to determine RH according to ASTM F2170.

•    Concrete slabs exceeding 3 lbs. (1,36 kg) MVER or 75% RH should be treated with a moisture vapor reduction product. Refer to Technical Data Sheets at for information on these products.

•    Use a moisture meter to check the RH of the wood flooring, surface of the substrate, and general jobsite area. Follow the flooring manufacturer's guidelines.


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

• Ready to use; no mixing necessary


1. Read all installation instructions thoroughly before installation.

2. Select the appropriately notched trowel (see "Approximate Product Coverage" section).

3. Spread adhesive evenly over the subfloor, keeping the trowel at a 45° angle to the subfloor.

4. Only apply as much as can be installed within 45 minutes.

5. Install wood flooring in strict accordance with flooring manufacturer's written instructions.

6. Adhesive transfer to the backing should be confirmed periodically by lifting the flooring material.


1. Immediately clean any adhesive smudges from the flooring material's surface with Ultrabond ® Urethane Cleaner while the adhesive is still fresh/wet.

Note: Ultrabond ECO 975 is extremely difficult to remove when cured.

2. Immediately clean tools with Ultrabond Urethane Cleaner while 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 be advised of the wood flooring 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.

1 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.
11 Working time is the maximum amount of time an adhesive can remain exposed to the air and still effectively bond to the floor covering.
111 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.
