I recently bought a bunch of slatwall on CL for $30, this included a 4x8 sheet, several 2x8 sheets, a few 2x6 and 4x4 sheets. I'm happy I found them on CL for this price as buying new is really expensive. Anyhow, I want to use the material to cover one wall in my garage. About 1/3 of the wall already has Drywall covering on it since it's the part of the garage wall that is common with the inside of the house. I'd like to cover the entire wall, about 14 feet from end to end. My question is can I just span over the top of that drywall and then go to the open studs or would it be better to add some 5/8 furring strips to the tops of the studs so that it's all even across the wall? and what about Vapor barrier? Do I need to add plastic behind the Slatwall before hanging it up? This is my first time covering a garage wall so I don't really know the best practices
