Help! I am a first time homeowner. I currently have linolium in my kitchen and want to repalce it with tile. I thought all I needed to was pull up the linolium and put down the tile. Reading some other postings on this board it doesn't sound that simple. Once of the postings talks about the floor being strong enought to support tile. How do I figure that out? Is there a book, website or software program that anyone could recommend. Obviously there is more to this than I thought. Thank you.
