Several months ago we had to take down the paneling in some sections of the den wall because of water damage on the outside wall.

We pulled all of the walls inside skins down and replaced it with paneling.

Now to the finger pointing. I suggested to my son that the paneling he purchased was to thin and that he should either glue it on a backer board or at the very least put Liquid Nails on the studs for additional support. Both vetoed because, "I had no idea what I was talking about."

Well here we are now with the paneling buckling on the wall giving a ripple effect.

So, do we pull the stuff down and purchase thicker paneling (8' ceiling) or should we try to save the paneling and glue it to some thin wood to add strength to the paneling?

In general, what would be the minimum thickness for paneling that will be nailed to wall studs?

If u can get paneling down without damage, would recommend 3/8'' S/R as a backer. Then glue and nail paneling.

A good quality paneling will not have much flexibility when handled, but still recommend a backer.

Agree with creahands but also recommend that the SR be installed horizontally, backwards. That way, the seams don't run the same way as the panels and you don't have to worry about filling in the joint. Another approach, a bit too rustic for some people, is to use T-111 plywood, 3/8 "

You feed them, cloth them and put them through school only to find out they think you are nuts, nice Don. I agree with the guys but think you'd be better off with new , thicker paneling but cost does always play a role
