Re-enforcing water damaged plywood?

Late last year a seal by the antenna in a 1992 18' Scout Nomad allowed some water to come in on the front right corner of the trailer. The plywood in the wall feels like it might have absorbed some water and dried out. I noticed it due to a small amount of the wallpaper peeling right up in the corner. The board still feels intact but tapping on it it seems to 'feel' less dense in the portion where the water came down. The board itself still seems quite intact, however.

What I'm wondering if there is anything to treat a water effected piece of plywood such as that to add more strength to it and seal it up in the event of future problems with the antenna seal. Perhaps something that would absorb into the wood? (I'm assuming the reason it feels less dense is that it is now a bit more porous)

Any suggestions are appreciated. I want to try avoid replacing that section as I have no idea how involved that might be!
  • You might be thinking of "Get Rot". Have a look at the damage, and at the product and see whether you think it could help.

    There are lots of videos showing the use of products like "Get Rot" available.
  • Your basic options are to (a) live with it how it is now (and keep an eye on things, making sure it's sealed against further water intrusion) or (b) take it apart and replace whatever water damaged material is there. There isn't any treatment you can apply to strengthen it, at least not without taking everything apart.

    Based on what you've written I would probably go for option (a) personally as it doesn't sound like a large area of damage, nor a serious structural problem at this stage. I will, however, say that quite often water damage proves to be somewhat more extensive than it at first appears.
