Might be best if I start from the beggining. The basement when we bought the house was finished. Definition of finished varies from room to room. Back side of the house not underground where the living room is they had attached brown paneling via small nails and looks like liquid nail directly to the block, and no sealer. Room in the basement on the front side of the house which is under ground they only painted the block with some type of sealer.
So I guess you say that the the walls are bare block walls with the exception of some type of white paint sealer. Paint may not be the right word, however the walls have been painted with something. Can't really say if it is sealer or paint tough.
"They" being who ever built the house 30 years ago. The wiring is ran inside the block. So if I add the 1 1/2" stud and 1/2" drywall I am adding 2" thickness to the wall. When I extend the electricsl box to be flush with the drywall I hope whomever ran the wiring originally left enough slack for me to extend. While writing this I thought about the possibility of pulling the wire back out of the top of the block and then straight down between the drywall and block wall. Wouldn't that make up for the thickness. A friend of mine tells me that I run the risk of shaving the insulatioin off and exposing the wire. Maybe I just have to be extra carefull and check it thoroughly. Anyway just a thought. Also I plan on leaving the electrical outlets where they are so I won't have to worry about putting a whole in the block to get them to fit. They are metal though, should I replace with plastic while I am in there?
Hope this isn't asking to much, I really appreciate your advice. I consider myself a capable guy, and like doing this type of work. So to save a buck or two for labor is always a plus. More for my wife and kids to have, RIGHT?!
