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