    I rebuilt my boat transom and needed a fungicide to control/treat the wood rot . After the removal of the infected wood , I received the Borate powder, I mixed the solution and treated the infected areas. I would like to know if the fungi was totally destroyed .

        Best Uses

        • Indoor
        • Quick Fix
        • Used to protect a beam

        Comments about System Three Board Defense Borate Powder:

        I had a seriously rotted 200-year-old beam that I applied it to. I followed mixing and application directions which were very clear. This was the first step in restoring the beam. It took two days to dry because of the location. I followed it with application of the epoxy. Next will be filling the beam and inserting reinforced iron bar. Your site provided me with the most complete information, both video and written. Comparing all the products that I found on the internet, I selected this because of price and informational support. Cutomer service was also very good.
