2071 TUFF LOK X-LINK WOOD FLOORING ADHESIVE
Taylor 2071 Tuff-Lok X-Link Wood Flooring Adhesive with Meta-Tec
®
Technology, is a high solids, cross linking, Amide-
Ester-Acrylate, resin-based adhesive formulated for the interior installation of dry-back parquet, engineered wood plank,
acrylic impregnated plank, and pre-finished and unfinished solid wood flooring. It is solvent free, has a low VOC content,
contains no hazardous chemicals as per OSHA Regulation CFR 1910.1200 and it is a nonflammable, low odor adhesive
that meets all federal, state, and local governmental indoor air quality regulations. This specially formulated adhesive has
good early strength buildup for immediate grab and gradually builds into a tenacious but resilient bond as the chemicals in
the adhesive cross-link.
Taylor 2071 can be used over association grade underlayment plywood, association grade particleboard underlayment,
cork underlayments, existing well-bonded vinyl tile and sheet flooring, terrazzo, radiant heated subfloors where surface
temperatures do not exceed 85°F (29.40°C), and concrete. Install above, on, or below grade, in the absence of excessive
moisture and alkali. While this adhesive is waterproof when cured, the wood flooring still must be protected from
excessive moisture. Although this adhesive retards MVT, it is not intended to function as a moisture barrier. The pH level
of concrete must be between 5 and 9 (do not install if over 9) and moisture level of concrete must be below 3 lbs./1000 sq.
ft./24 hours using an anhydrous calcium chloride test kit according to ASTM F-1869 test method. Relative Humidity
readings according to ASTM F-2170 should not exceed (RH) 75%. If both tests are performed the RH test is the qualifying
standard. Follow wood flooring manufacturer’s guidelines for allowable levels of moisture. Wood underlayments must
have a moisture content below 12% using a Tramex or Delmhorst wood moisture meter.
SUBSTRATE PREPARATION
Substrate must be sound, smooth, level, clean and dry. It must be free of dust, dirt, wax, loose paint, incompatible curing
compounds or fire retardant chemicals, fungicides, release agents, sealers, or any other foreign substances that might
interfere with a good bond. Substrate must be level to 3/16" in a 10 ft span (4.8 mm in a 3.048 m span). Note: When
installing thin gauged wood (solid or engineered) irregular substrates may telegraph through as adhesive pulls wood down
during curing stages. Therefore substrates must be properly leveled to prevent telegraphing. Fill all cracks, holes and low
spots with a polymer modified Portland cementitious patching or leveling compound and allow to fully cure before applying
adhesive. High spots must be ground level. Substrate, adhesive and wood flooring must be acclimated in an enclosed
building with the HVAC operational and running for at least 72 hours before, during and after the installation. The
installation temperature and relative humidity must be controlled between 65° and 95°F, and between 30% and 60%
relative humidity, subject to the floor manufacturer’s requirements. Open time will vary with temperature and humidity or
porosity of the substrate. Note: Wood flooring must be exposed to the air when being acclimated. Follow the wood
flooring manufacturer’s guidelines regarding site conditions and installation.
