Product Overview

Tim-bor Professional should only be applied for eradicating fungus off of wood and for protecting new wood from future infestation.  If treating any wood with an existing infestation, you should always use Bora-Care. Bora-Care will penetrate through an entire piece of wood much deeper and ensure proper control, and it will protect the wood you are treating forever.

Tim-bor Professional is an insecticide, fungicide and wood preservative for the protection and treatment of lumber against fungal decay and wood destroying insects. Tim-bor is a water soluble, inorganic borate salt with insecticidal and fungicidal properties. It is an effective treatment for wood to kill and prevent infestations of decay fungi including white rot, brown rot (i.e. Poria) and wet rots. Tim-bor does not treat mold or prevent mold from growing.

What is Timbor?

Timbor is a wood preservative that works as an insecticide and fungicide.

What is the active ingredient in Timbor?

The active ingredient in Timbor is disodium octaborate tetrahydrate, a natural borate compound.

What is a borate compound?

Borate compounds are derived from mineral deposits that contain the element Boron. These compounds are use in the production of many products including ceramics, glass and medicines and also work extremely well as insecticides and fungicides.

Why is Timbor considered an insecticide and fungicide?

Insects are exposed to the active ingredient by eating treated wood or by ingestion while grooming. Borates are a contact toxicant to fungi. The borates prevent metabolism of food by insects and fungi causing death.

How is Timbor applied?

Timbor is applied to the surface of bare wood as a liquid. It can also be applied as a dust into void attic and wall void areas for labeled insect control.

How does Timbor work as a wood preservative?

When Timbor is applied as a liquid to the surface of bare wood, it diffuses into the wood to make the wood itself toxic to wood destroying organisms such as wood decay fungus or drywood termites.

Is Timbor concentrate a liquid?

Timbor comes in a powder form that is used as a powder or mixed with water to form a liquid solution. To create a 10% solution mix one pound of Timbor to one gallon of water. This solution must be applied twice to a bare wood surface. To create a 15% solution, mix 1.5 pounds of Timbor to one gallon of water. This solution can be applied only once to the wood surface.

Is Timbor labeled to treat wood decay fungus?

Timbor is labeled for the control and prevention of wood decay fungi including white rot, brown rot, poria and wet rots.

Is Timbor labeled for the control of carpenter ants?

Timbor is labeled for the control and prevention of carpenter ants by applying Timbor dust into active ant galleries and into areas where ants may enter the structure.

What wood destroying organisms is Timbor labeled to control?

Timbor is labeled for the control and prevention of drywood termites, wood destroying beetles, wood decay fungi, carpenter ants and termites.

Can Timbor be foamed?

Timbor can be foamed using equipment designed for foaming applications. Foaming requires a 15% solution in conjunction with a foaming agent. A dry foam is recommended for best results.

Does Timbor affect ornamental plants?

Yes, over spray on plants or spills near the plant roots can kill or retard plant growth.

    Timbor DIY vs Commercial

    By Jeff on 05/28/2011

    A national chain quoted me $2,900 to spray the trusses of my new home under construction. I paid about $65 for the Timbor and spent about 4 hours spraying. Absolutely worth it!

    Timbor

    By Russ on 03/14/2011

    Easy to use, included measuring cup, just added to water in a separate 5 gallon pail and agitated with a drill and paint mixer, pour into pump up sprayer and saturated walls of older garage. I sprayed twice waiting about 30 minutes between application, for good penetration, had it been spring or summer I might have made several wet on wet applications as the wood was old and dry. I purchased the 25 pound pail and have several more structures to treat. My (former thanks to DMOPC) pest control person said that Timbor was a great low cost addition to a complete termite treatment. I also note that Timbor is especially good at repelling carpenter ants, and fungus which I believe is the cause of dry rot. Thanks DMOPC

    Good Stuf

    By Tim on 10/18/2010

    The price at DoMyOwnPestControl was better than I could find elsewhere and their support was great. This stuff (borate minerals) has been around a million years and is known to make wood toxic most insects including drywood termites, carpenter ants, ants and wood destroying fungi. It works by dehydrating them. It doesn't kill subterrainian termites, but those are easier to find by inspection (mud tubes). It is as advertised and, applied properly will work. I had drywood termites and ants crawling all over the structure before treating the outside with this stuff and now they are all dead, gone and discouraged. I've covered up the outside wood (siding, shingles, etc.) and so long as the cover remains intact, this stuff will continue to do its job.

    Small quantities not available

    By Laura on 04/23/2010

    Verified Purchase

    Product was easily mixed. Would have preferred directions for mixing smaller quantities on package. Might use BoraCare next time for effectiveness but small quantities of that were not available and it was costly.

Q
How much Timbor should I spray over the wood to be treated is enough? Can I apply either too much or too little?
A
You only need to apply the Timbor solution so the wood is wet.  You should not apply the product so it starts to drip and runoff, that is too much.  Just enough to wet the surface and evenly coat all exposed sides of the wood, like you are spray painting it.

Q
Where can I buy Borate or Tim-Bor in Canada(Hamilton,ON)

I've had work done in the basement and discovered powderpost beetles in one section and want to treat before we continue. PLEASE HELP!

A

We apologize but we do not know of anywhere in Canada that carries the products we do.  Many of our Canadian customers will have a product shipped to someone in the United States that they happen to know like a friend or family member, and they they forward it onto Canada. We do offer FREE shipping within the US.

Q
Can you dip stud or beams using Timbor?

Can new wood studs or beams be effectively treated by dipping in a tank filled with a Tim-bor solution frequently stirred so it remains in suspension? Could full immersion like this be more effective than spraying? It may also be quicker and more economical, with no overspray. Also, are oil-based or water-based sealers or paints better for sealing the dry treated wood and extending the life of the Tim-bor treatment, i.e., which type is preferred? Should any surface powder be brushed off for better adhesion before painting or sealed in?

A

Yes you can use the dip method when using Timbor however, you will still be getting the same 15% solution rate as you would if you were spraying it on and getting the same 1/16" penetration level as well. To get the full penetration all the way through the wood we recommend using Boracare. Yes, you would want to get the surface powder left behind by the Timbor off the wood before using any finishing products.

Q
Can Timbor be applied with a sponge or hand-pump sprayer?

I have a small cellar and would like to apply Timbor to the ceiling without having to buy or rent a tank and hose sprayer. Thank you.

A
Timbor can be applied with a paint brush or a gallon pump sprayer. To create a 15% solution, mix 1.5 pounds of Timbor to one gallon of water. This solution ratio ensures that only one application needs to be performed. Please be sure to read the Timbor Product Label before use for complete instructions.

Q
Will Tim-bor Professional work on treated wood?
A

Tim-bor Professional cannot be applied to wood that is already finished with a stain, sealant, or paint. If the wood is pressure treated, there is no need to treat it with the product, however if you still would like to ,Boracare would be the product to use and expect it to absorb and dry slower than on raw untreated wood.

Q
We have Timbor. Can we use it to treat plants for fungus and insects?
A

Timbor can only be applied to raw wood.  It would likely kill any vegetation it was applied to.  If you are looking for something to apply to plants for fungus and insect control, you can use something like Bayer Advanced 3-in-1 Insect, Disease, and Mite Control.

Q
Can I put finishes over a reclaimed fir beam after I treat it with Timbor on the interior of a home?

I have several big reclaimed fir (I think) beams going up on the inside of a new home. Can I put something like a clear finish over them after treating with Timbor, after it has dried completely?

A

Yes, it is recommended that you use a finish and/or sealant after using Timbor. It will potentially dry with a texture so you may have to sand it first.

Q
Can Timbor be mixed with ethylene glycol to help it penetrate into the wood? This would be less expensive than using Boracare.
A

Timbor will only penetrate 1/4 inch into the wood since it is a powder.  It should only be mixed with water as directed on the product label.  If you do mix it with other products, it will clump and not work the way you would like it to.  If you need better penetration, Boracare is the only way to do so.

Q
Can you use Timbor with anti-freeze to make your own Bora-Care?

Can you mix car anti-freeze with the powdered Timbor...and paint it on...seems like a cheaper solution to Borocare..which u have to mix 50-50 with water...

A

Timbor is not labeled to be used in this manner, and we can make no recommendations on this usage. Should you have any further questions feel free to contact the product manufacturer, Nisus, directly at 800-264-0870.
