If you can treat all sides of the wood when applying Boracare, that is best. However, if you can only access one side, then it would still be recommended to apply two coats of Boracare at least 20 minutes apart. If the wood is still very fresh, then it is best to let it cure for at least a few days before applying Boracare.
Keep in mind that for prevention you can dilute Boracare at the 5:1 ratio with water, per the product label.
There are a few things that could cause Boracare to leave residue once the application has dried. One possibility is that the solution was not mixed completely before it was applied. Boracare is best mixed in a separate container such as a 5 gallon bucket and using an impeller-type mixer such as one you would use to mix paint. If Boracare is applied very heavily (to the point of runoff), then there can be excess product which the wood cannot absorb, and that could dry in a whitish finish on the surface of the wood. Next, when you have very old wood there could be little to no moisture left in the wood, and that moisture is how the Boracare penetrates through the wood. So this really would go back to just using more Boracare than the wood can absorb. Finally, if there were any kind of finish on the wood such as paint, stain, etc., then this would have to be removed completely before you could apply Boracare or other borate products.
You can use warm soapy water and a scrub brush to remove any excess product that may leave residue on the wood.
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.
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.
The most popular product we sell for wood-destroying beetles such as powderpost beetles is Boracare. This is a borate wood treatment that can be used on any raw wood that is absorbed into the wood and stays there. You should dilute and apply Boracare at a 1:1 ratio with water when treating active insect infestations. Please keep in mind that we only ship within the US.
If the raw wood of the door is exposed, then Boracare is definitely the product you want to use. Mix it at a 5:1 ratio for termite prevention or a 1:1 ratio for an active infestation and spray as many sides of the wood that you can get to. Boracare will soak into the wood and last for the life of the wood to protect it from wood destroying insects and fungus.
Bora-Care will only penetrate the wood it is applied to. For floor that is stained you will either have to pull it up and treat the unfinished underside or sand down the top to the raw wood and apply.
Yes, Boracare can be applied in your garage. It will not affect metal or wiring.
For furniture your options are limited for treatment. If the wood is in its all natural raw state without any stains or finishes on it you can use a product like Boracare. Boracare will absorb all the way into the wood and eliminate Wood Destroying Fungus, termites and other wood-destroying insects that is effecting it and last for the life of the wood. It does not stain the wood or leave behind any visible residue, but becomes one with the wood and any insect that ingests it dies.
If the furniture has a finish on it, you would either have to drill holes throughout it and inject something like the Boracare or a foam, or the option most go with, hire a
