Hi Everyone,
Been working on my basement, and I wanted to get some info and feedback from the pros. I had an old post "here" but I have a new direction I want to take and I think that topic is closed.
Current Basement Floor: Rubber backed carpet (gross), glued to some old vinyl tile (assuming asbestos). The vinyl is attached to the slab with black cutback (also assuming asbestos).
Plan to fix Floor: Rip up the carpet, lay down 6 mil poly vapor barrier on top of the old vinyl tile\glue. Overlap and tape the seams to form sealed floor. Run poly 12" up the walls. Lay down 1" XPS foam insulation and tape\seal\spray foam edges, seams, etc. On top lay 5/8 T&G plywood that is countersunk tapcon'd to the floor. On top of that, rubber\pvc interlocking tiles. 6mm? Hopefully that will keep my ceiling at about 6"5.
Current Walls: Somewhat moldy sheet rock screwed to some old 1970's retro paneling, nailed to some random 1x2s which are nailed into the painted cinder block walls. The cinder block has a pink colored paint (I hope it is paint and not mold...) which is flaking off due to some old water damage. The black\gray on the wall is not mold, it is where the pink paint is peeling\flaking off, and the original cinder block is showing. What I find interesting is that the flaking paint is about as wide as a front door, which happens to be pretty much above that spot. Guess I will find out when I open the ceiling under the door!
Plan to fix walls: Remove everything from walls and go back down to painted cinder block. Steel brush walls and wipe clean. Poly foam board\spray foam the rimjoist. 6 mil poly plastic the walls (Dexter style) then put 2" XPS foam board on the walls. Do I build a 2x4 wall (with trex below sil) here and sheetrock? I saw a 1.5" XPS foam board that has furring strips which I could tapcon to the foundation wall, and then attach the sheet rock to the furring strips. I don't need the walls to be structural, the basement is for cats and storage.
Moisture Situation: The basement is usually a little musty. We have also had very minimal water on the carpet when it rains\floods. The house is pretty well graded and my gutters are clear. I think it may have been the window well and over by one corner, which I am going to need to seal up as well. It could also be behind another wall\corner. I still have 2 more major walls to rip down. I also have some hydraulic cement which I can apply if I find a really leaky spot.
Thanks for the help - looking forward to sealing this basement up for good. I will feel much better about my family's health.
