Titebond® 771-Step Adhesive, Moisture & Sound Control combines the superior properties of a moisture cure adhesive with the ability to be used as a moisture and sound control system, primarily for wood floor installations. This product enables the installer to protect the floor from subfloor moisture and glue it down in one application, saving labor and time. Once cured, the product is water-resistant and is not adversely affected by exposure to moisture or water. It provides a tough, flexible and tenacious bond to a variety of substrates.
Alternatively, Titebond 771-Step can be used just as a one-part adhesive simply by using a different sized trowel. Please see specific application guidelines in this document for details and instructions. It can also be combined with Titebond 531 or Titebond 531 PLUS Moisture Control Systems to achieve unlimited moisture protection. The elastomeric characteristics allow the adhesive to move with the wood as it expands and contracts over the life of the floor. It has unparalleled green grab and strength development, spreads easily, and cleans-up better than urethane products. Titebond 771-Step is most often used to secure solid wood, bamboo, cork, and engineered hardwood flooring. It can also be used to install plywood, ceramic tile, marble, cork underlayments, and stone inlays for residential and commercial applications.

MOISTURE CONTENT LIMITATIONS (One-step adhesive, moisture and sound control method): The moisture content limit for installations is 15 lbs. or less/1000 sq. ft./24 hours per a Calcium Chloride Test (ASTM F1869) or 85% relative humidity (RH) when tested with an in situ probe (ASTM F2170). To ensure protection against subfloor moisture, 100% substrate coverage and adhesive transfer is required.
MOISTURE CONTENT LIMITATIONS (Adhesive Only Method): Titebond 771-Step may be used for above-, on- and below-grade applications and on all substrates listed in this specification guide. All applications are susceptible to moisture and should be tested for moisture prior to installation in several locations within the installation area.
Acceptable conditions of concrete for above-, on- and below-grade applications are:
- Less than 3 lbs. /1000 sq.ft./24 hours on a Calcium Chloride Test (ASTM F1869)
- Less than a reading of 4.5 on a Tramex Concrete Moisture Encounter
- Relative humidity (RH) of 75% or less when tested with an in situ probe(ASTM F2170)
Acceptable conditions of wood substrates are a moisture reading of less than 12% or be no more than 4% different from the flooring being installed when using a Tramex, Delmhorst or equivalent wood moisture meter. If subfloor moisture conditions do not meet above guidelines at the time of flooring installation or they could exceed them at any time after installation then a Titebond moisture control system should be used.
- This product cures very quickly!

- Do not install solid wood below-grade
- Do not use on concrete with curing agents or sealers (except for recommended Titebond or Franklin products)
