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 Bora-Care after about 3-5 years. We wouldn't be able to tell if your porch floor will swell or not, we would recommend to call Nisus (800) 264-0870 to check with them.
Bora-Care should be applied uniformly and evenly on all sides of raw wood either by spraying or painting on as directed on the label.
All areas that need to be treated with Bora-Care will need to be stripped and sanded prior the application for the application to be effective. All exposed areas will then need to be sealed prior to a rain event.
Bora-Care will last the entire life of the wood to protect against wood destroying insects, wood rot and fungi. As long as the pine siding is untreated and in its raw state, BoraCare will absorb completely throughout the wood and last the entire life of the wood when “locked” in with a water sealant, paint or stain.
For siding measuring 13/16 in (¾ inch) thick, refer to the Lumber Charts on pages 12 to 14 of the product label for linear and square foot coverage that one gallon of BoraCare will cover at the 1:1 or 2:1 ratio.
BoraCare can be used anytime of year as long as the wood itself is not damp or high in moisture. To ensure your BoraCare application lasts the entire life of the wood, it is recommended to apply a water sealant, stain or paint within 30 days of the application.
The beetle activity you are seeing could be new beetles coming into the barn. We would recommend inspecting the wood inside the barn for any holes or debris to determine if there is activity inside the wood that has been treated.
If reapplication of BoraCare is determined necessary, we would suggest applying a paint, stain or sealant within 30 days to ensure the life of wood protection.
When applying Bora-Care to a ceiling, you can either spray or use a paint brush to make an application. If you decide to spray, you can lay a tarp down to protect the floor and any items below. If you use a paint brush to apply Boracare we would still suggest using protection for the items below. There could be a bumpy residue left which can be sanded off if needed.
Boracare can be used on ANY raw wood that is not painted, stained, or sealed. Since it dries on clear, there should be no problem with stain, paint, or seal when you are done or while applying a clear coat finish. Please view the full product label for more information.
Drying times after Bora-Care can vary depending on the thickness of the lumber, humidty and air temperatures. It’s recommended to allow 72 hours for the Boracare to completely dry before sanding, painting or staining the wood. Once the application has completely absorbed throughout the wood and dried, there should not be any sticky residue left on the surface. Lumber that is greater than 10 inches thick do require 2 applications or if only 1 or 2 surfaces of the wood can be treated.
Please refer to the Lumber Bulletin and the Bora-Care Total Wood Preservative for Use Prior to Installation of Lumber Section on page 13 of the product label for more information.
We do not recommend applying Bora-Care to firewood. Burning wood treated with any insecticide would release the active ingredients into the air. Burning the wood without treating with any chemical will kill anything in it.
You should be able to seal the wood with anything labeled for this purpose without affecting the efficacy of Bora-Care.
Bora-Care can be used on an raw unpainted/unstained wood that is used for building furniture including tables. Please view the full product label for more information.
