Paint ought to stabilize water absorbsion but you would have to cover both
sides and all cut ends. I suppose that you could just begin by painting
all surfaces with the paint you are going to use as your dirt color.
I have a 10' by 13' and only painted as I went along. I eventually had
problems with the sandwich unlaminating, but that, I think was only
because I relied on weights to hold the homosote to the glue. I should
have both glued and screwed the homosote to the plywood.

I don't think so, but we sure had fun on an N-scale layout we finished
which already had Homasote. This is Great Lakes climate at its best.
BTW, this stuff was screwed down and just contracted and expanded
"beautifully".
Now interestingly, on our own home layout ( HOm Swiss Metre Gauge ) we
havent had any such problems. But of course it's 1/2" ply, 1/8' Lau-an
and handlayed track on woodties.

Personally, I don't see any advantages to the use of Homasote and
several major disadvantages. The sponge behaviour being one.
There are other methods to eliminate noise that have none of the
disadvantages of "Achoo sote ".
