Woodworking Experience:
Found product to be very easy to use, wish there were instructions for application of the product.
The PEG product is quite easy to use, I used a 50%solution which was a little above the 40% recommended by information I was able to find. Will use the product again if needed

Great stuff....
Great product. Just mix it with hot water and stir to dissolve. Then insert wood to soak. Use an old waste basket. It takes some patience, but it works well.

Woodworking Experience:
Walnut Round
I used PEG to treat a 2 ft walnut round that was 3" thick. I just let it sit submerged (weighted down) on painting blocks in a large container for 6 months, then I dried it and planed it flat. Best looking round table now.

I work at a museum and we will be getting a large cross section from the trunk of an American elm. The trunk was over five feet in diameter and the section will probably end up being about 4-5 inches thick. I want to use the method that will provide the best stabilization possible. I used PEG on a bitternut hickory cross section about 3 feet across and 3 inches thick in the past and had good results. More recently I used wood juice in an attempt to stabilize a white oak cross section about 40 inches across by about 3 inches thick. After much work and a couple of years of waiting the piece checked very badly. Is this because white oak has very dense wood or is PEG a better wood stabilizer?

Mark R on Sep 6, 2016
BEST ANSWER: My only experience is with peg I had good results.
I would like to make coasters from cedar rounds 4 inches across and 3/8 of an inch thick. How long would I have to soak them in PEG to keep them from splitting?
Carl F on Jul 7, 2016
BEST ANSWER: I would soak them a few weeks at most. I have treated green cedar of this size and it doesn't take long.
how long do you leave green wood in the solution before it is ready to be used for turning etc?
Carroll P on Aug 15, 2015
BEST ANSWER: The time a piece requires for treatment is determined by four factors. The density of the wood, the depth of diffusion you require, the strength of the PEG solution and the temperature of the solution. Patrick Spielman has a book, "Working Green Wood with PEG" ( ISBN 0-8069-8924-6) that includes tables compiled by the Forest Products Laboratory for typical values with one and two inch slabs of end grain walnut.

Personally, I found the tables to not be very relevant. The PEG solution is expensive to mix in any volume so I rough turn the pieces to 2-3" wall thickness and place the piece in a poly bag with a 25% to 30% solution. Silver maple, mimosa, red oak and hackberry have taken several weeks. Plan on at least a couple of months. the treated wood is great to turn but it is messy. I wear goggles and rain gear.
Can PEG be used on chainsaw wood sculptures?
Orrin M on May 30, 2015
BEST ANSWER: It can but there are limitations. If you want to stabilize found or freshly felled wood that is not exactly "green", PEG works well. If you want to stabilize chainsaw sculptures that are dry or are drying, immersing the piece in a 25% solution of PEG for several months will keep the wood from developing cracks after it dries.

The limitation, from my experience, is that the PEG solution will only penetrate a few inches. The wood inside the PEG absorbed layer is wet but not stabilized. It could develop cracks. I treat large blanks for turning by placing the rough turned pieces in a 20-25% PEG 1000 solution for 10 - 14 months. When I remove the piece from the solution, it is very easy to work. It takes a few weeks to dry. Since I remove the interior wood, the limited penetration is not a problem.
I have a ash log 12' long 46in. across would like to make table tops 4in thick. Is it better to treat or kiln dry.Whats the best way to prevent cracks? Marv
marvin k on Oct 3, 2016
BEST ANSWER: This stuff should work great! Make your cuts first though, soak the slabs for at least a month or more before you set them out to dry. Then let it dry for a year even if you can
Does the PEG add Any color to the wood?
Sonny on Dec 2, 2016
BEST ANSWER: I carved a 6 foot wizard from a butternut log, then soaked it in this for 30 days in a special tank I made from fiberglass to minimize the amount of PEG I would need. Turned the wood virtually black. Had to carve off about another 1/16" over the entire piece to get the butternut color back, but that DID work.

Can wood treated with PEG 1000 be kiln dried?
Ronnie on Aug 10, 2016
BEST ANSWER: Yes. PEG treated wood can be dried quicker than normal wood, but make sure you get full PEG saturation before kiln drying.
I have a log 3 feet in diameter and 8 feet long how would I treat it's also White Oak also is going to face off one side to make a sign out of it?
Paul M on May 2, 2017
BEST ANSWER: Seal the end grain with AnchorSeal. The log will forever be wet inside until you cut it. Then you might consider PET or air or kiln drying.

I don't believe there is much you can /should do to a log other than treat the end grains
I want to know how much PEG1000 is penetrated into the wood. (ex. exposed end grain 2 inches)

Is there a way to test this? Maybe use some kind of chemical substance for testing or some kind of machine.

Thank you
Kuladej L on Feb 19, 2016
BEST ANSWER: Need to try and cut pieces longer. Soak for 30 days
I bought this product in April 2016 and did not have occasion to use it until recently. Imagine my surprise when I took off the lid for the first time and found a solid plastic-like block. The self life according to the MSDS that you have on your site says the shelf life is 36 months. Not so. This is especially surprising since the lid was actually sealed with tape because of a recent move. What happens now?
Skip T on Jan 19, 2019
BEST ANSWER: My husband purchased this and told me that it does come as a solid,. He chips it with a chisel into small pieces and dissolves it in hot water. Once dissolved, it stays that way. I don't know how hard your product is, but it is a little harder than candle wax (some places sell it as a hard pellet). Good luck!
All reviews are saying to SOAK the wood. But I have 3 8' long, 2" thick, 18" wide pieces of magnolia. How do I use PEG?
Benjamin Z on Jul 10, 2017
BEST ANSWER: You build an eight foot long, 20 inch wide and 6 inch deep trough out of 3/4" marine plywood. Reinforce all seams with 2x4 framing since full of water it will be very heavy. Either fiberglass the interior of the trough or lay in a layer of 6 mil plastic sheeting at a big box building supply. It will take a lot of PEG. A recommended 30% solution will take maybe 50 pounds of PEG. The result will be check or crack free, the wood will be gorgeous but a little darker from the PEG solution. You will need to soak the wood, as in submerge it in the PEG solution for maybe 2-3 weeks at temperatures above 80 degrees F. which is the melting point of PEG. In other words build your trough outside in the Summer in a sunny place. The process is a diffusion process in which the molecules of PEG slowly move through the wood cell walls and replace the sap water inside each cell. It really works. For table tops, I use a children's wading pool with a plywood lid.
Do I have to use PEG immediately after cutting ends of Ponderosa Pine for side tables? (2-3 inches thickness.)
Jan P on Apr 7, 2016
BEST ANSWER: The greener the wood the better I think. This product is replacing water molecules with a kind of plastic almost that won't evaporate, therefore keeping the wood from shrinking and cracking. Adding peg to a dried and cracked piece of wood won't do anything
Oak table 2’ dia 1” thick. How long do I soak?
Mike T on Mar 7, 2020
BEST ANSWER: My guess is 3-4 months. I haven't treated anything this large. I usually soak my wood in water for a week first. Oak is very hard to stabilize. Drying time is also 3+ months.
What is the rough conversion of this 10lb container into gallons?
D R on Dec 22, 2019
BEST ANSWER: The product comes with mixing instructions, or you can look it up online. I think I mixed 10 pounds of PEG with 11 quarts of water, but You should not trust an old man’s memory. It makes enough to fill a Home Depot bucket about a third to a half full. When I add wood to treat, the wood displaces enough liquid that the bucket is full.
Can you use this for fresh cut live edge pieces?
Grayson W on May 1, 2017
BEST ANSWER: Yes, this, in time replaces the water in the wood with PEG. Do not put dark colored wood in same tank with light colored wood. The dark will stain the light colored wood. This allows a wood turner to work the wood as it were green, without the splits, checks, or shakes. Personally, I like using the PEG. For what it is worth, this is pure PEG, not the same as antifreeze which is poison.
What can I use to glue slabs treated with PEG? Since PVA glues don’t bond well, would the tire on polyurethane glue work well?
Eamon C on Jan 10, 2020
BEST ANSWER: I use PEG primarily with large and small chunks of wood before I turn them on a lathe. I’m not familiar with PVA glue. However, I have had good results using exterior grade wood glue in all types of wood work.
I have two large pieces of fresh cut pine. About 3.5' long and 2.5 feet wide. They are between 3.5" and 4 inches thick. What percent solution should I use and how long do I soak it for? Can I put the solution in a plastic kiddie pool? Can I stack them on top on each other when soaking?
Angela R on Jul 21, 2018
BEST ANSWER: i think the info sheet with the product is probably on line as well. It deals with %, something I didn't have to deal with given the small pieces I was using. I was just winging it. The pool idea seems fine, although I have found in the past that making a trough just large enough and lining it with polyethylene allows me to be more efficient with the amount of solution. It seems to me that the time to soak is based on days per inch thickness of the wood. Pine will be faster than hardwood for sure. And you may need to replenish the solution with more PEG as it is exchanged for the moisture in the wood. Hope that is at least part of your answer.

BEST ANSWER: i really dont know
how to check obtained solution is PEG or not / valid or expired?
Naveen K on Jan 16, 2020
BEST ANSWER: This brand comes in a powder form and does not expire. Once you have turned it to liquid you can store it in a sealed container for later use. If it starts to solidify you can simply stir warm water with it to regain the consistency needed to soak into wood.
how long do I leave the tree slices soaked in Green Wood and how long after can I use the wood?
