Im am going to put a new wood floor in our bedroom. It is the type where you lay and underlayment and then the floor fits on top. We have concrete under. I am going to find someone who knows how to do it to help me with it. As I prepare it I have some questions. While pulling up the wood strips that holds down the carpet there are some nails in the concrete. How do I deal with them? A couple came out but left little chips or nicks. I am assuming that wont be a problem, but how do I deal with all those little nail heads sticking up? Second, some parts of the concrete are cracked. Not giant cracks but some are about 1/8th inch. Should I fill them with a filler and what kind of filler? I think ants may come in those cracks but I may be wrong. Thanks for any help.
