Bora-Care would be the best product to use, applied twice to the three surfaces you can get to. It will penetrate up to 4 inches with 1 application, and up to 8 with 2. If you choose to drill you should drill whatever size hole you need based on what you have available to inject the Bora-care with. Typically if you have an injection piece of equipment, 1/4 inch or 1/8 inch holes are used. Please see this technical bulletin from the manufacturers of Bora-Care that explains about drilling and injecting into wood. See page 5 and it will give specifics about the drill pattern, etc.
Boracare really is designed to only be applied to raw wood that has no finish or treatment on it of any kind. The teak oil may prevent the Borcare from fully penetrating into the wood. If you can sand some of it off (depending on how deep the oil penetrated into the door), you may be able to apply the Boracare with sucess. However, we cannot guarantee that it will soak in the way its intended to since the oil has been applied.
Yes, you can treat the same wood with Boracare. The previous treatment with Timbor will have no affect on the absorption. Both products are borate-based and become one with the wood after application.
Typically Boracare dries in 24-48 hours and does not need to be rinsed before sealing. If there is any white residue left, you can remove excess Boracare using soap and water, but we would try to avoid doing this unless there is clearly too much product applied. You only need to apply to wood until wet, but not dripping.
Bora-Care starts working as soon as it has soaked into the wood. When wood boring insects such as termites consume the wood treated with Bora Care, they will ingest a lethal dose which will kill them. Bora Care will also remain active in the wood for the lifetime of the wood, so it will continue to protect the wood for it’s lifetime.
You should apply Boracare to raw wood. You can then apply any stain, sealant, or paint after the Boracare application has dried, usually 24-48 hours.
It is safe to put insulation back once surfaces treated that have been treated with Bora-Care are completely dry. You can either use the same insulation or replace with new.
Yes, you can apply Bora-Care with Mold-Care over an application of Bora-Care.
No, Boracare is not labeled for carpenter bees. For carpenter bees, we would recommend using our Carpenter Bee Kit. Please also check out our Carpenter Bee Guide for more tips on how to treat and prevent them in the future.
Yes, you will treat the wood directly and let the application dry completely. Bora-Care will not absorb into the soil or treat the soil in any way.
We would recommend contacting the manufacturer of Boracare directly to see if this application would be safe or harmful to the bees. You can reach Nisus directly at 800-264-0870.
You will need to allow the wood to dry completely before applying the finish. We would recommend waiting at least 3-5 days after the Boracare application.
Per the manufacturer, Bora-Care can be used in conjunction with a tent treatment but it's recommended to be applied afterwards. How long after the tent treatment, depends on the chemical the professional company uses, they should be able to tell you how long you have to wait.
Bora-Care will not kill palmetto bugs. It is labeled for wood-destroying insects such as termites, carpenter ants, powderpost beetles, etc. Insects need to ingest wood that has been treated with Bora-Care in order for it to kill them.
You can use Bora-Care but would need to seal the wood before putting it on the ground.
Boracare can only be mixed with water. It would be recommended to apply Boracare first and then apply the linseed oil once the Boracare is dry.
In order to get the best results, Bora-Care needs to be applied to raw wood and at least one full side of the wood that needs to be treated in order for it to be absorbed, treat and protect the wood. If it's just squeezed into the cracks and crevices the treatment will not be effective because most of the solution will be left on the painted/stained wood. If you would like to spot treat, then you can spot treat the areas of activity with Jecta, which is a ready to use form of Bora-Care, but you would have to drill into the wood to make the treatment.
Bora-Care penetrates faster when applied to all sides and you get a more complete application, but if you can only apply to one side it can still penetrate up to 4 inches with 1 application.
The idea when actively treating for mold and wood boring pests is to treat the termites first with Bora-Care at a 1:1 ratio and then come behind that and treat with Bora-Care with Mold Care at the 1:5 ratio. Per the manufacturer, this can be done in back to back days.
Yes, Boracare can be applied in your garage. It will not affect metal or wiring.
