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 get what you pay for.....I've always preached it and now I'm falling victim to my own warning. I paid someone to finish my basement, and they did a decent job through the framing, rough-ins, and hanging the drywall. But then my guy's idea of quality really started to show. I had asked for a wall texture to match my upstairs (which I consider a knock-down orange peel). What I got instead was a messy version....he just shot mud on kinda randomly with no knock-down/troweling process. It doesn't look horrible, but it's enough to bother me. So I wasn't man enough to pull the plug on the operation right after he applied the texture. I let him finish the job thinking that maybe after a few coats of paint things would look better. Turns out his painting skills are about as good as his mudding skills. What's my best option for cleaning this up now? I've been reading and I think that maybe a coat of Gardz, followed by some sanding, followed by a complete skim coat and then paint might be a good option. But I'm not sure how this will work over the existing texture. Any advice from the pros would be very helpful. By the way, I luckily asked for a plaster ceiling and he sub'd that out to someone who did a good job.
