I would like to put hardwood flooring rather than a laminate flooring in my home. I am on concrete slab. Can I go with hardwood and how do I put it down? Does it have to be glued? Everytime I go to a store to ask a question I never get the same answer and I am confused about what I should do. Can you please help me and recommend what type of flooring I should use? If you say that I have to use laminate, then I will, but I would rather have finished hardwood; i.e., Bruce's flooring and others I have seen in different showrooms.
