Worked as advertised
I had some small cherry rounds that I did not want to split, I put them in plastic ziplock bags with some of this (so it would soak in good without using too much product). Left them for about two weeks, flipping the bag every day to redistribute the product. and none of the wood split.

So far, so good
Easy brush application on freshly cut wood cookies, the size of dinner plates. Applied product several times after drying on subsequent days. Little, if any fumes. Used a disposable brush. It's been 2 weeks since final application and no cracking or checking.

Pentacryl use on log cookies
The product worked well. I applied it with a brush, and did multiple applications over several days. It was a little difficult to tell if the wood was saturated with the product. Brush clean-up with soap and water between applications worked well.

The cookies are now drying, so the effectiveness (or lack of) will be evident in the next few months.

What is the difference between PEG and Pentacryl? I am trying to make tables from green cut disks of oak, maple and popular.
pat on Aug 2, 2016
BEST ANSWER: Look up polyethylene glycol in Wikipedia (registered TM). There is some information about elements being toxic, but a lot has to do with the percentage by volume. The article also discusses its properties include effective displacement of water and does go into detail about the underwater wooden vessels that have been preserved using PEG.

Besides the chemical make-up, there may not be much difference in the effectiveness of either product. However, before you lay out your cash, you may want to contact the manufacturer(s) directly.

Hope this helped.

Does this product change the color of the wood?
Edwin on Jan 25, 2019
BEST ANSWER: From my experience on a few items it does not change the color appreciably. There is a slight muting of the natural wood color.
im new to this stuff i have a fireplace mantel im making the blackwalnut is still semi green if i put a few coats on the wood after it dries could i put a coat of poly or epoxy to make it really shine? or will this make it shine? thank you
michael s on Jul 25, 2019
BEST ANSWER: Pentacryl is a stabilizer used to prevent green wood from cracking or splitting during the drying process. It is not a finish. It will not shine or polish. When it is dry, it can be stained and finished with water based or oil based finishes.
I have a 6'x3' oak slab that I plan to make into a picnic table. It has been curing in my shed since December. How much pentacryl do I need and is it too late to apply it now (June)? There are also a couple of cracks developing--any advice?
Kate M on Jun 9, 2019
BEST ANSWER: I would use approx two quarts. Use one initially, wait a couple of days and reapply again, but less. You are going to apply the product on both sides. I would use cauls to keep things flat at first. Good luck.
We have wooden fence posts that we'd like to preserve from the Sun would this work to help from future sun damage?

BEST ANSWER: No. This is to preserve green wood. There are much less expensive ways to preserve fence posts. Look for a wood sealer
