Really did the job

This purchase was for joists in an older porch that were showing some rot infestation. We applied two coats as directed using a common pesticide-type sprayer. The effect was excellent and the rot retardation visible. We still had to sister or replace where the rot was more severe but this product was a tremendous time and money saver. We're switching sides of the porch for phase two and will be ordering more.

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 .

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.
