Taylor Meta-Tec® MS PlusTaylor Meta-Tec® MS Plus Wood Flooring Adhesive with Meta-Tec® Technology, is a one component 100% solids, cross linking, MS polymer-based adhesive formulated for the interior installation of wood block parquet, engineered wood plank, acrylic impregnated plank, bamboo and pre-finished and unfinished solid wood flooring. Taylor MS Plus also has good concrete moisture inhibition capability as well as good sound reduction property that meets the IIC and STC building code requirements.
MS Plus is solvent free and isocyanate free, has negligible VOC content, contains no hazardous chemicals as per OSHA Regulation CFR 1910.1200 and 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 quickly builds into a tenacious but elastic resilient bond as the adhesive cross-links. Taylor Meta-Tec® MS Plus can be used over APA grade underlayment plywood, association grade particleboard, fully secured cork underlayments, existing well-bonded vinyl, tile and sheet flooring, terrazzo, cementitious and anhydrite screeds, concrete, and radiant heated subfloors where surface temperatures do not exceed 85°F (30°C).
Install above, on, or below grade, in the absence of excessive moisture. While this adhesive is waterproof when cured, the wood flooring still must be protected from excessive moisture. For regular wood flooring applications not involving the moisture inhibition system using Taylor’s Glide-On trowel, moisture levels of concrete must be below 3 lbs. per 1,000 square feet per 24 hours (1.36 kg per 92.9 m2 per 24 hours) using an anhydrous calcium chloride test kit according to ASTM F-1869 test method, or below 75% relative humidity tested in accordance with ASTM F-2170. The moisture content must be within the limits recommended by the wood flooring manufacturer, generally a maximum of 75% RH. 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. For concrete slabs with elevated moisture levels up to 10 lbs. per 1,000 square feet per 24 hours (using an anhydrous calcium chloride test kit according to ASTM F-1869 test method), and up to 85% RH (tested in accordance with ASTM F-2170), use the Taylor Glide-On one step application trowel to apply the moisture barrier and installation coat of adhesive. See the trowel recommendation chart and follow Wood Installation instructions below. If using MS Plus as a moisture barrier or for sound reduction in addition to installation, all conditions and exclusions as stated in the most current Taylor MS Plus Wood Flooring Adhesive Installation System Warranty for Concrete Moisture Remediation must be strictly adhered to and met.

Easy to apply and use
After checking out a few youtube videos to see how the pros do it, I gave it a shot and it went really well.
It spreads easily, but maintains it's edges with the grooved trowel, and remained workable for at least an hour, even in higher temperatures here in Texas (solvents and glues and things usually dry faster here.)
Things I didn't know that would have been nice to know - spreading liberally, the 4 gallon container covers about 100 sq ft. That tends to go farther as you develop technique, but I ended up ordering less than half of what I needed.
Also, it uses an odd trowel size, so either buy the trowel listed here, or find a way to use the trowel add-on that's included in the false lid in each 4 gallon bucket. If you don't need the moisture barrier, snip the smaller tabs flat - you'll see what I'm talking about.
