Bora-Care mixed at 1:5 ratio would not be strong enough to eliminate an active termite infestation. This requires a 1:1 ratio.
When applying Bora-Care to structural wood in the home, you only need to apply the product once. It will last for the life of the wood. If you are applying to exterior wood like a deck, porch, or fence which is exposed to rainfall, then you would either need to use a water sealant after the Boracare is dry, or you would re-apply Boracare after about 3-5 years.
You could sand wood that has been treated with BORACARE as long as it is completely dry.
If you have subterranean termites, we would recommend doing a trench around the home. You will dig a 6 inch by 6 inch around the structure of the home. We would recommend using Termidor SC. You will use 0.8 fl. oz. per gallon of water. You will use 4 gallons of solution per 10 lineal feet. The termites travel in the walls and will be eradicated within 90 days.
You can use Boracare on pressure treated wood as long as there is no stain, sealant, or paint on the wood. If the wood treated with Boracare is outside exposed to the elements, then you want to apply a water sealant after the Boracare has dried.
Yes. Bora-Care can be applied to new, green wood. Just keep in mind that the dry time may take longer than older, seasoned wood since the green wood contains more moisture than seasoned wood.
When using Boracare to treat for an active infestation of wood fungus it is applied at a 1:1 ratio for wood that is 4" thick or greater. Use a 3:1 dilution ratio for wood less than 4" in thickness. You can spot treat the areas that have active fungus and then use the 5:1 for future prevention in the non effected areas. You should be sure to address the moisture issue in the area before or during treatment of Boracare and apply a vapor barrier after the product has dried. Please see the product label for complete application instructions.
