this type of chemical replaces the water. i will vacuum the next pieces in my chamber, and no it doesn't coat the end grain it soaks up through the entire piece! so far so good i have another sample of their product i am also going to try in my chamber. i have stabilized wood that was around 15 percent moisture content!! it depends on how long you run it and how good of a pump you have, getting the pressure down low enough to suck the moisture out and replace it with such chemicals.
read what this product is about i am still in the testing procedure with this and i am very impressed without putting it into my chamber!!! they have a video on their site, not to mention its food safe and great for the environment! i will be giving it a run tomorrow with the chamber, with both chemicals!! also i went from 30 percent or higher on the red maple burl to down to 15 percent as of now!
