AdvanTech subfloor stands up to the rain until the house is dried in.
On this build, we used AdvanTech subfloor, which has proven itself to me in the past when exposed to months of rain without buckling. New this time was AdvanTech’s adhesive, which we all love. Applied with their long-nosed foam gun, you can easily butter the tops of the joists without bending over. The days of oozing tubes of adhesive messing up hoses, cords, and hands are over.
