Bostik’s EFA+™ exhibits a long open time making installation easier and faster. This adhesive has low VOC’s and does NOT contain any water.

This adhesive can also be used to install plywood as described, as well as ceramic tile, marble, and stone inlays for light commercial and/or residential applications.
