We had a sheet vinyl floor installed over concrete last fall in our partial basement....installer first put a skim coat of concrete down - let "cure" about 2 hours, then laid the floor using manufacturer's recommended adhesive. At that time he told me that I may see some "bubbles" in the floor over the next few days...that was normal (?). That never happened, but 6 months later a large area of the floor..toward the middle bubbled up!! note: we haven't had any water down there. He was here and cut that area to check for moisture....there wasn't any..rather, the floor beneath was tried and flaky!! What causes this and what are my options now for a replacement floor. I appreciate any help/info.....please!! :)

I am planning to install a vinyl floor in our kitchen in our 80 year old home. There is currently a vinyl floor on top of a wooden subfloor. Since the wooden subfloor is a bit raised from adjoining rooms, I believe it was layed down on some previous flooring. (By the way, the previous owner installed the vinyl sheet in 1995 , so asbestos is not an issue) I realize I can lay down vinyl flooring on top of the previous vinyl flooring, but how many times can I do this? In a few years we are planning to move and keep the house as a rental, and I anticipate having to replace the vinyl periodically. At what point do you have to stop layering the floors and actually tear them out? Secondly, the current vinyl floor is curling in places and is torn in others. What kind of product do I need to make these repairs before installing the new vinyl? Thirdly, we have though about installing vinyl tile instead of vinyl sheet because it appears easier. However, it would seem to me that the tile would not last as long- especially in a kitchen that gets a lot of use and needs to be cleaned often. Any thoughts? Thanks.
