There are multiple questions that I would like answers to about finishing my basement. First question is drop ceiling. I am OK with installation and understanding the grid pattern. I want know what recessed lights can be used, how many are needed per sq. footage and bracing requirements for support. What problems have come up with heat from the recessed canisters. I don't want to burn the house down! I like the fact of being able to access my gas, water and electrical lines without having to rip out drywall. Other questions are about flooring. I have ideas about hard wood flooring. I would think that it would not be a good idea to put this type of flooring directly on concrete but I am also concerned with cost. What would be the easiest way to moisture barrier the floor for this application? Also what is a good sealant to use for a concrete floor? I also have one other question, has anyone ever finished a basement with superior walls as the basement walls? I am going to be insulating the pockets and would like to know if anyone has run into any problems with these walls.
