You should be able to buy the treatment and brush it on the exposed side.

I thought the point of "pressure treated" was that solved that penetration issue. I have yet to see much of a color difference with viewing a cross section of cut to length PT board.
Are we talking about "new" eco friendly treated wood?

The green brush on copper/arsenic treatments I believe are no longer available for sale to the public, or very restricted.

My thinking was, the OP had no real concerns to be worried about.


Based on my experience, the pressure treatment penetrates the surface just enough so that it looks good from the outside. But once a cut is made, you'll see the untreated inner section.

All I can say is, if you cut a pressure treated board, you might want to seal that cut with similar treatment to hold off the rot as long as possible.
