Thanks for the tips Gary.
The adhesive coverage seems about what I figured. But the sealant is not what I expected. They recommended the 531, which apparently gives 400 sq ft coverage for a 1 gallon container. Is this the one you had in mind? (They mentioned it was 2-part, mix them before pouring out.) If so, the sealant cost would be much less.
Actually I liked the plastic sheeting and tapcon screws approach (not looking forward to messing with glue), and I think it would be more economical, in the $0.75 per sq ft range. But when it seemed the sealant+adhesive was more like $1 instead of $2 (e.g. Bostik) I began to lean towards that as a "safer" approach. Questions/concerns I had about tapcons: (1) damage to the concrete (2) holes in the moisture barrier (have you heard of / tried dipping the tacons into calk?) (3) what tool would I need to drive the tapcons, regular Black & Decker drill/screw driver OK?
I left more than 1/2" in some rooms upstairs, hence the extra shoe base (actually a flexible polymer thing called a bead from HD)
. I had a couple of questions on that: If the floor level goes up and down, should I stick the flexible bead slightly curved in places to hide the gap to the floor, or just keep it flat and parallel to the bottom of the baseboard? This polymer bead stuff only comes in 8' lengths, so I'd have to make joints in the middle of the wall which I don't really like, not sure there are any options? Also wonder what kind of adhesive to use, to attach polymer to MDF?
I'm using Insulayment to provide some thermal and sound insulation. Current floor seems cold under the carpet. Used it upstairs and it cut the sound down compared to felt paper (even though it adds about $0.50 per sq ft).
Any other reasonably priced recommendations for concrete and wood moisture meter?
