Steve Padgett of DAP products Inc. explains the benefits of SmartBond: a single can will adhere up to 400 linear feet, or about 12 subfloor panels; avoids foam “blow-off” when dropping panels in place, due to stiffness of the gel; and it adheres well to rigid insulation, without “burning the foam”. It’s available in three grades: Subfloor, Heavy Duty, and Landscape.
