Thanks for the reply. At this point, my wife and I are at our wit's end, and want to finish this (*&%$ floor once and for all, and are tempted to go with overkill. I want to use the best cement or compound possible, put in a good aggregate (pea gravel maybe?) put in a heavy wire mesh for reinforcement and screw it into the existing concrete floor and...anything else I can think of.
My question is this: a) is there a better type of concrete I could be using than Level Quick for strength and ability to adhere to existing concrete? b)if I pour in thin layers as you suggested, how much time should I allow between layers (the bag suggests a couple of hours - which I did in the last pour (although I was still going deeper every layer than you recommended). Longer?
