Boric acid
Boric acid, also called hydrogen borate, boracic acid, and orthoboric acid is a weak, tribasic Lewis acid of boron, which is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other chemical compounds. It has the chemical formula H₃BO₃ (sometimes written B(O…
What is the best antifreeze to prevent rot on wood?

Can you use propylene glycol and boric acid on wood?
Allow the wood to dry for two hours between applications. Boric acid and propylene glycol penetrate wood well due to their water-solubility. However, this excludes them from use on wood that is below the water line. The antifreeze mixture should be applied only when rain or snow is not forecast.
How do you kill rot in wood?

Is there a chemical to stop wood rot?
Boric acid (borate) is one of the most effective fungicides for use in treating wood rot. It can be applied to wood during construction to prevent future rot, or as a treatment to stop an active decay fungus from growing.
How does borax treat wood rot?
Arrange the raw wood so that each side can be treated with the Borax solution. Check that you are able to flip the pieces on edge and over onto the other side to get an even coverage of Borax onto the wood boards. Take the pump sprayer and the Borax to a water supply and mix up a batch of Borax wood treatment.
Is antifreeze a good wood preservative?
Antifreeze, boric powder and boric acid can be effectively used to eradicate and prevent rot in wood. Boric acid and glycol are both toxic to a wide range of fungi, organisms and insects that perpetuate rot in wood. Antifreeze can have two active ingredients: either ethylene glycol or propylene glycol.
Does ethylene glycol stop wood rot?

What is borate wood treatment?
Borate wood preservatives are low-toxicity treatments used primarily on indoor wood that is protected from weather. Borate wood preservatives have been used to treat wood for interior construction including joists, sheathing, sill plates and other uses for over 70 years.
How long does a borate treatment last?
How long will Bora-Care® stay in the wood? Since Bora-Care® is derived from minerals, once the active ingredient diffuses into the wood it will remain indefinitely. There are no natural forces that will degrade or break down the product inside the wood.

What is the active ingredient in Shell Guard?
The active ingredient in Shell-Guard RTU is disodium octaborate tetrahydrate, chemically similar to a combination of boric acid and borax, but with higher concentration of boron which is responsible for the effectiveness. The borate is toxic to fungi that cause rot and decay, subterranean and drywood termites, carpenter ants and wood boring beetles.
How long does it take for a shell guard to dry?
The amount of time it takes Shell-Guard RTU to dry depends on the density and porosity of the wood, and temperature and humidity. In warm, dry temperatures the drying time may be as little as a few days. Under humid conditions it may take weeks of drying time before a stain can be applied.
What causes white residue on logs?
Occasionally a white residue may appear over knots and other areas of the logs. These white deposits are created by a small amount of the borate crystalizing on the surface. Their appearance does not mean that the treatment will not work! Wipe this residue off with a damp sponge.
Is shell guard good for wood decay?
If you just built a new home and the borate treatment was not included in the package from the manufacturer, Shell-Guard will be your cheapest insurance against wood decay and bug infestation. If the weather prevents from applying it outside, the interior application as effective as an exterior due to the penetrating properties of the Shell-Guard products.
Do you need to use water to treat logs?
You will be happy to know that you don't need to use water to apply borate treatment against wood decay and bug infestation. When it comes to treating a log home, the drier and more absorbent the surface is, the better the treatment will be. If you haven't done it already, this could be your perfect interior project this winter.
Is borate toxic to beetles?
The borate is toxic to fungi that cause rot and decay, subterranean and drywood termites, carpenter ants and wood boring beetles. It is also toxic to beetle eggs that may be in the wood at the time of treatment or eggs deposited sometime later.
What We Tested
We did not test treatments that might present chronic health hazards or are not aesthetically pleasing. Copper napthinate, found in products like Copper Green and Termin-8, for example, has a horrible smell and is not recommended for indoor use. It also stains the wood green.
How We Tested
Samples of fir, western red cedar, and pressure treated lumber were cut into roughly 11/16” x 1½” x 12” samples. One of each was set aside as a control (not exposed), and another was left untreated and exposed as an exposure control.
Teak treatment
Halberg-Rassey recommends Boracol, a glycol borate formulation, for maintenance of teak decks. To apply (DIY, Boracol or Bora-Care), clean and allow to dry for several days; the drier the wood, the more quickly and thoroughly it will be drawn in. Apply one moderate coat, covering about 350 square feet per gallon.
Observations
We coated the samples with three coats of each preservative, allowing drying time between applications. System 3 Wood Defense and the DIY borate solution dried within 24 hours, leaving a few crystals on the surface, which easily brush off. Moisture is thought to help the borate penetrate more deeply, so a light misting after drying should help.
Three Year Progress Report
Dimensional stability. One reason pressure treated lumber is not very useful in boats is warpage. As anyone who has been to the lumber section at a big box home improvement store can attest, firring strips and plywood sheets seem more prone to warpage if they’ve been pressure treated.
Liquids
Success with any liquid treatment hinges on drying time. If you are coating, you’ll have to wait until the timber is fully dry. Storing liquids on board can be more challenging than it is with solids.
Glycol Only
Drying is slow, as you would expect. There is limited evidence of rot protection. It is most often used for prevention of dry wood cracking.
How to treat rot on wood?
A preferred method to treat rot might be to soak the soft wood, or evidence of rot, in antifreeze, even if you cant do any other repairs at the moment. Paint it on or stray it on with a coarse spray. Avoid mist-like spraying to avoid breathing in unhealthy amounts of glycol.

Ethylene Glycol, Rot Treatment & Epoxy
Its been since about 2006 since The Chemist posted "Ethylene Glycol in Epoxy: A study of insidious degradation" . .
Re: Ethylene Glycol, Rot Treatment & Epoxy
One thing I can say:''Stay away from polyester resin on wood''. With or without ethylene glycol, it definitly delaminate from wood.
Re: Ethylene Glycol, Rot Treatment & Epoxy
I would call the tech guys who make the epoxy you intend to use. Or call a bunch, maybe different formulations react differently.
Re: Ethylene Glycol, Rot Treatment & Epoxy
Thanks. I have seen those studies. Those who speculate suggest the borate salt interferes with the bond. So as you say, straight EG by itself or w 50% water was a "go" according to the West SHORT TERM study.
Re: Ethylene Glycol, Rot Treatment & Epoxy
Is it possible to apply normal commercial car anti freeze, or would it be better to try and find pure ethylene glycol ? I nearly finished the framework on my boat and I'm looking for ways to treat it.
Re: Ethylene Glycol, Rot Treatment & Epoxy
Car antifreeaze has elements of other chemicals in it- rust inhibitors etc. eBay has lots of results for ethylene glycol. In looking for a rot treatment for my skiff I ended up using this; Multi Shield 5Litre Wet Rot-Dry Rot, Woodworm Treatment

Ethylene glycol, or glycol, readily available as permanent auto antifreeze is the most versatile and effective treating agent for stabilizing wood against the dimensional changes caused by variations in water content. Glycerol and sugar solutions act similarly to glycol, but nowhere near as rapidly.
