John,

My brother runs a fertilizer/seed/farm supply business (Meherrin) in Hawkinsville and he can get the Solubor for you in 50# bags.

Thanks Danny.  Maybe I can get the L & L in Milledgeville to order it for me.  If not, Hawkinsville is not that far.

Yes, they should be able to order it as it is a fertilizer additive for mixing with liquid fertilizer.

And the polypropylene glycol in antifreeze is not what you want as a wood preservative.

John,

I got you a bag today if you want it.  I can bring it Saturday.  If you don't need it, I will keep it as I use a lot of it.

I have been using the Navy mix that calls for 1 gal of antifreeze, 4 and ˝ lbs of borax and 3 and ˝ lbs of boric acid. This mix does require heating to 260 F. The best I can determine, this is similar to Boracare. I get the borax at Wal-Mart which is the cheapest place I have found. You can get the boric acid at Wal-Mart as roach power but I find it cheaper (even with shipping) to get it from www.chemistrystore.com in 55 lb bags (currently at 89.10 + shipping.)


Farm supply stores can order Solubor for you.

The above mix is water-soluble and will leach out when the wood is exposed to water. It is recommended for dry locations where it will not be wet. It is primarily for insect control.

While I would like to dip my lumber but I have not set up a tank for this. I have a drain board made from a 3 ft wide piece of metal roofing with removable plastic sides. Use a sump pump to pump the solution over the lumber. The removable sides let me pick the lumber up with a FEL. It takes about 5 gal of mixture to prime the system plus the amount you use. If dipping, the minimum solution would be considerable more. I use a 5:1 mix ratio, which is recommended for dipping or flowing. If spraying, you should use a considerable stronger ratio like 1:1 or 1:2. When applying with a roller, I have used a 1:3 ratio.

When treating lumber, I usually have it on the FEL beside the “tank”. Then brush the sawdust off the lumber. (Don’t want to spend money treating sawdust.) Lumber is placed over the tank and the solution is flowed over the lumber using a sump pump and hose. I wet it good on one side and the edge closest to me, then turn it over and do the other side and edge. Lumber is then stacked on the far side of the tank and the process repeated. Do not try to drain the solution off the lumber but let it stay and soak in to the lumber. After the stack is completed, the lumber is moved and left dead stacked for a day or so. Then it is sticked and dried. Sometimes when cutting 8 ft 2 x 4, I will stick it horizontally and vertically as it comes off the mill in a stack 3 wide by 4 high (1/2 inch stickers) and band it. Then treat the bundle as a unit. Less handling that way.   

Here are some photos of my facility.

Hi Guys,   I have used Timbore for a number of years and have done real well with it.   I started 10 years ago with massive powder post infestation in my shop racks of air dried English Walnut.  The ppb will crawl a mile to find the English Walnut sap wood.   I unloaded the whole shop of all the wood and sprayed with 10% Timbore powder in hot water.   

The way it works is killing the bettle as it is going in.  The holes are caused by the larve or hatched larve coming out.  Its too late to kill after you see the holes for that generation.   I quarentined all the wood for several months before restacking in the shop.  I had to retreat one or two boards again but no big deal.   The 10% solution is supposed to be a permanent treatment and it has done just that.  After the first bad several generation infestation I now treat any new wood going into an adjacent storage area and have had no bugs in that wood.....ever (knock on wood  :) )

If it is ppb you are after, the Timbore has worked real well in my case.

Question - if one goes the "antifreeze" route, what are the downsides to using standard green Ethylene Glycol based antifreeze instead of the special low toxicity Propylene Glycol antifreeze?

Other than being careful about animals licking the wood while it's wet, I would presume that the low amount of antifreeze absorbed by the wood is insufficient to be harmful to humans when working the wood.

@Den Socling , I know it has been a day or two since you wrote in reply #43 above:

"And the polypropylene glycol in antifreeze is not what you want as a wood preservative."

I have searched to answer "why?" this is so, but to no avail. Would you tell me why this is true? I happened to buy some borax, boric acid, and rv antifreeze; but, don't want to waste my time if this is a poor performer. Thank you. -Mike

Den hasn't been on in a couple years.
Glycols are not wood preservatives their purpose is to hold a wet edge for the borate to move on. Either glycol will work for this purpose. For borating dry wood what you're wanting is a solution that dries slowly. As I mentioned in another thread a day or two ago borate only diffuses into or out of a cell when it is above fiber saturation point, when you can see the wet in the wood. That is what the glycol is doing. So your RV antifreeze is fine, often cheaper. I watch the drying conditions and doctor the mix with glycol based on how much I need to keep it wet, I'm stingy and cheap. BoraCare runs about 50/50, I typically run 5-10% glycol with dry wood unless it is very bright and dry. This isn't French perfume, hit it hard and multiple times if possible. I prefer a dip tray if possible.

BTW a few drops of dishwashing soap, not foamy just a few drops, will help break the surface tension and let the liquid wet out better.
