Can I apply Boracare with Mold Care over basement drywall that has had old termite and mildew damage?

My basement had wallpaper over drywall and when removed had old termite damage but not any active termites and mildew around the floor. Can I use a roller to apply to the drywall as a preventative to both termites and mold and if so would I use the 1:1 ratio or the 5:1 ratio.


We dont recommend using a product like this on drywall as the extreme amount of moisture you would be applying could compromise the stability of the structure. If there is mildew on the drywall we highly suggest replacing it with pre-treated drywall. The studs and joists behind the drywall however could certainly be treat with the Boracare with Mold Care and you would use it at a 5:1 ratio. Only if you are having active infestations would you use a 1:1 ratio and it would be with just Boracare. Please let us know if you have any other questions.
