Jtmedic. I have not understood this issue. If the advantech is so good, and doesn't even swell while sitting in water, why bother to paint them?
What JC said is true. This stuff is suppose to be the trick, but the following is just my my opinion, once you cut the stuff, leaving the newly cut edges exposed without the outside treatment which is placed on the original sheet and it?s edges from the manufacturer, I am thinking it is a good Idea to paint, at least the edges generously. This may not be necessary but as the old saying, an ounce of prevention. advantec, diamond, and the newer gorilla glue flooring is made specifically for sub flooring and has an impressive testing performance track record. I noticed the gorilla went up from 25 to 28 a sheet at my local Home Depot. So far, I have only used advantec but fully intend to try the gorilla 🦍 which is made in my neighboring state of Alabama for comparison.
I will add,, Good job on the nucs. So far I have only used the advantec as tops and bottoms for the no warpage advantage and I love the stuff. It is made with a polyurethane glue, use a good mask when cutting.
