My house is a little over a hundred years old and i have started removing the old walls in my back bedroom. After removing the beyond repairable drywall, i found tongue and groove panneling. Underneath that is a layer of paper, and then more tongue and groove. Underneath that is 2 layers of paper, and then horizontal boards, like 1x4s, and beyond that the walls, unbeknown to me were dense packed with celluse.

What should my plan of attack be. Should i remove all the beadboard and drywall over the horizontal boards, or should i just drywall over the 2 layers of beadboard?

 

You usually need to consider the depth of your window and door jambs. So for instance, if you've removed your window trim, and there is 1" of jamb sticking out past the studs, you will either need to double rock the walls, or fur them out 1/2", then apply the 1/2" drywall.

It sounds like at the least, it would be desirable to leave that last layer of wood on the wall (to keep in the cellulose) and then apply the drywall. But IMO, it would all depend on the thickness that leaves to the face of your door and window jambs.

 

As you take off the trim, make sure label it so you'll know where it goes back. This may sound silly, but once it's all in a heap, it's hard to tell.
