I needed to replace my 40 year old tub faucets. Seeing as the fixtures back to the chimney (IE no rear access) I had to go through the wall. My wife decided that since I was doing this anyway, we should get rid of the tile and replace with a 5 piece tub surround.
Plumbing is done. Tile removed. Now I have the walls. The paper on the walls (was green board) is pretty much gone. There is still alot of glue on the walls as well. I need to replace drywall where the faucets are. I also have a few smaller holes where my prybar went through while removing the tile (these are sporatic). Do I need to replace all of the wall board? Can I just seal it and skim coat it? I am hoping to get this done soon but if I don't HAVE to replace the wall board, I'm thinking that would be best. As I said, I will be putting up a 5-piece surround over the walls (Some 8x12 tile around the top as well).
The greenboard should not be used at all. I would remove it. Especially since you will not want to install any tile on this stuff. And a five piece tub surround means it is a cheap one which will leak at some point.
according to your desire....you should need to replace all of the wall board. and just seal it.
Does this advice have any experience behind it or is it just some spouted verbiage ?
Please state your past experience in remodeling and why you would use wallboard and what do you consider , "sealing".
