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 has no moisture limitations and calcium chloride or in-situ RH testing is not necessary. 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. Being able to glue down and control moisture and sound in one application, it saves both labor and time. Alternatively, Titebond 771-Step can be used just as a one-part adhesive simply by using a different sized trowel.
