Can I use liquid nails to attach toe plate/sill plate to concrete floor?
I wouldn't recommend bonding sill plates directly to a concrete floor. Any wood in direct contact with basement concrete is asking for trouble. Concrete is porous and will wick moisture to anything placed on top of it. In order to prevent moisture wicking into the sill plate and consequent danger of mould, mildew, and rot, it's better to lay a 12" wide sheet of 6 mil polyethylene vapour barrier between the concrete and wood sill plate, then fasten sill plate to concrete with tapcon screws. Wrap the poly up on the inside of the drywall (if you're finishing the walls again) to also protect the drywall from wicking moisture from the concrete.
