Q. Which construction adhesives are best for gluing plywood subfloors to joists under wet conditions?

A.All construction adhesives that are labeled AFG-01 and/or ASTM D 3498 are capable of doing the job. One of the tests to pass for these specifications is a wet lumber test. Solvent-based construction adhesives typically dissipate the water better than latex- and urethane-based adhesives.
