Superior 3-in-1 Wood Flooring Adhesive

Designed exclusively for DuChâteau, Atelier Series and American Guild hardwood flooring, DUAG-87 Superior 3-in-1 Wood Flooring Adhesive is a unique one-component wood floor adhesive polymer based on modified silyl technology. DUAG- 87 is specifically formulated to be used as an adhesive or as a moisture vapor retarder to reduce the transmission of water vapor from the subfloor for the applications where moisture could impact the performance of the wood flooring. NO PRE-INSTALLATION MOISTURE TESTING REQUIRED. DUAG-87 can bridge cracks up to 1/8” and will provide a powerful adhesive bond. Its environmentally friendly formulation is easy to trowel and suitable for all green building projects.

DUAG-87 is ideal for glue-down installations on all grades for all types of engineered, solid or acrylic impregnated wood flooring, bamboo and wood flooring, designed to be installed using the glue down installation method, that may require protection from damage due to subfloor moisture transmissions. When used as an Adhesive and Moisture Barrier, DUAG-87 reduces moisture to acceptable limits.
