Steve from Tappahannock, Va writes

Will Bora Care or Tim-Bor prevent fungus growth around nail heads in painted pine siding where water can enter?

Nails loosen. Water can seep into the painted yellow line siding allowing fungal rot around the nail heads and also at end cuts.


Bora-Care and Tim-Bor should only be used on raw, unfinished wood.  It should not be used on wood that has been painted, sealed or stained.  If applications of either product are needed, the wood would need to be stripped down to it’s natural state before application.
