C from Irvine, Ca writes
Would there be any benefit to spraying just one side of the bare roof plywood that is exposed inside my attic? Does it only penetrate thru the outer bare laminate and stop at the glue layer?
Apply Bora-Care solutions only to bare wood, plywood, particleboard and other cellulosic materials where an intact water-repellent barrier, such as paint, stain or sealer, is not present. The glue should not pose any issues. If you can treat all sides that is always better, but one side would be suffficient if there is not access to all sides.
