Q

What precautions would be required to use Timbor or Bora Care on wood for furniture building?
I use a sawmill to cut walnut and oak for furniture building. I have an active powder post beetle problem. I believe the Asian Ambrosia Beetle is the culprit. I would like to use Bora Care on the known active lumber and Timbor as a preventative on newly sawn wood. My concern is safety during milling and working with the wood later on. What precautions would be required to use wood treated with either or both of these products for typical furniture building. Unlike many uses of lumber where handling of the wood is minimal, wood used in building furniture gets a lot of hands on contact. Thanks, Mike Waters

The Boracare would be the more appropriate product of the two for both active infestations and prevention of beetles and other pests. Timbor will leave a white powdery film on the surface of the wood and will only penetrate a 1/4 inch into the surface. Boracare, if mixed thoroughly before applying and not over applied, will dry completely clear and penetrate all the way to the center of the wood. Once an application of either of the products is dry, it would be safe to handle the wood bare handed or use tools to work the lumber into furniture. If you wanted to check with Nisus the manufacturer regarding any safety inhalation precautions if you use the Timbor powder and cut it after treating, you can reach them directly at 800-264-0870.

If you are foaming for active you should drill directly into the wood they are infesting and foam into the gallery where they actively are. Be sure to review the product label for complete instructions.

Q

Would Tim-bor or BoraCare be recommended for mold in a crawl space?

A

The only product that we carry that will treat both fungus and mold on wood is Bora-Care with Mold-Care. You can use this product on any raw wood or other cellulosic material (without paint, stain, finish, etc.). View the BoraCare Mold & Fungi Bulletin for more information.

Q

Can I apply Bora Care over a previous application of Tim-Bor?
I recently had Tim-bor applied to beams inside my 200+ year old home to treat powder post beetles. Looks like Bora-Care is the better product.

A

You can absolutely apply the Boracare over the top of the Timbor application without any additional surface prep being required. As long as the wood is still in its raw natural state, you can spray the Boracare mixture right onto the wood.

Tim-bor Professional can be used on raw, untreated wood to prevent wood destroying insect infestations and decay fungi if used as directed on the product label. As long as you wait until the application has completely dried to use the sauna, there should be no problem with treating the exterior. Do keep in mind however, that this product leaves a white powdery coating after applied. If you are want the wood to look like its original state, you may consider using Bora-Care instead, as it dries clear. It is also advisable to apply a water sealant after applying a wood treatment for wood that is exposed to the elements, if the sauna is outdoors.

If you are mixing Timbor in water and creating a foam with a foaming solution and foamer, then you would use 1.5 oz of Timbor per gallon of water and use a high expansion foam. Keep in mind that drilling into and injecting a product like Timbor into all your wall voids is a tedious and labor-intensive application that is often best left to professionals. We have a great Carpenter Ant Treatment Guide here that may better assist you.

Q

How long does it take to dry and be ready for stain on a log home? This is in high-altitude Colorado.

A

The dry time for Timbor honestly is dependent on the ability of the wood to absorb the product and how heavy you treat it. It could be a few hours before the surface of the wood is dry or even a day.

Q

Will this product work on fresh-sawn wood?
I have a portable sawmill I am using to cut lumber from the trees I'm clearing for a cabin site. The wood is stacked and covered as it should but it is getting mold. Can this product be used right after it's cut on the mill to prevent this or does the wood have to be dry?

A

Timbor Professional does not treat mold or prevent mold from growing. Mold is a surface issue caused by excess moisture and will continue to thrive as long as conditions are favorable for it to thrive. You will either want to give more air between the stacks if possible, or treat the wood with Borac…

Timbor Professional does not treat mold or prevent mold from growing. Mold is a surface issue caused by excess moisture and will continue to thrive as long as conditions are favorable for it to thrive. You will either want to give more air between the stacks if possible, or treat the wood with Boracare with MoldCare rather than Timbor to treat and protect it as much as possible. You can apply Boracare with MoldCare to freshly cut wood, but the more moisture in the wood with it being fresh/green the slower it will absorb into the wood. The wood doesn't have to be completely dry, but if you can give some dry out time after cutting that would be ideal before an application.

Q

Will TIMBOR affect the foil backing on OSB plywood?

A

Tim-bor Professional will only penetrate the outer layer of the wood (about 1/4 inch) so it is more for protection or for treating fungus on the surface of the wood, so it would not affect the foil backing on the OSB Plywood.

When treating a log home for protection against termites and wood boring beetles, you would want to spray the raw unfinished wood with Boracare rather than Timbor. Timbor can leave behind a white powdery residue on the wood that you may need to remove prior to staining or sealing the wood after treatment. Timbor also does not penetrate into the wood as far as the Boracare would which is another reason the Boracare would be the superior product for your needs. No matter which product you choose to apply, plants around the home would need to be temporarily covered to protect from overspray as the ingredient in the products could damage a variety of plant types.

If Timbor Professional is being applied to raw wood within a structure such as studs, beams, or floors, it would be protected from the elements and would not need to reapplied after the initial treatment to the wood surface.

Tim-bor Professional would not be recommended to treat any active infesations of wood boring insects as it only penetrates up to 1/4 inch. It will also leave a white residual behind. In most cases if a wood destroying insect is found within the frame of a piece of furniture your options are as follows:

Option 1- Strip down any stain or finish on the wood down to its raw natural state and apply a product like Boracare to the raw wood surface and then you can refinish as desired once dry;

Option 2- If stripping the finish off isn't an option then you would need to drill holes in the needed places of the furniture and insert a product like Jecta. Both the Boracare and Jecta absorb into the wood so that as the insects inside it eat the treated wood they consume it and die from it. Both products also last for the life of the wood to protect it;

Option 3- If neither of those are an option for you then you would need to hire a company that has a heat treatment or fumigation treatment chamber to put the furniture within to kill all the insects within it without doing any damage to the item.

Timbor should only be used on raw wood that ideally is new. Timbor is not water-repellant and it will not take care of any rot or mold on the wood. Timbor will only penetrate 1/4 of an inch into the wood and will leave a visible white residue on the surface. Boracare or Boracare with Mold Care are your other options. As with Timbor, the Boracare will need to be applied to raw natural wood but it can be old or new. The Boracare will penetrate all the way into the wood and will not leave a visible residue on the surface. If the wood is going to continue to be exposed to the outdoor elements, you will need to seal it with a stain or finish of some sort to protect it. If you do this, the Boracare will last for the life of the wood. Boracare will treat and prevent (depending on the rate you use to dilute it) for wood destroying insects such as powderpost beetles, termites, and carpenter ants, as well as wood-destroying fungus/rot. The Boracare with Mold Care will cover all of these same preventative measures and it also kills and prevents mold. You can also reference our article on How To Treat For Dry/Wood Rot.
