I need to tile over some really crappy, 30yo, worn-down sheet linoleum. The house itself is ~1890 and while my father did a lot of work on it, he went with sheet lino in the dining room and kitchen due to uneven flooring that he didn't want to make a huge project out of. I want to avoid rolls of lino. What is the best way to deal with the uneven floor?
Originally, we'd bought a treatment for the floor that would allow us to tile over the top of what's already there. However, it's been suggested that vinyl tiles will just pop up regardless because the floor is not completely level. At the dining room to living room doorway there is even a 12 inch, 9 degree slope instead of a step.
Pulling up the floor and replacing it is beyond the scope of what we're willing to do. We just want a new floor surface, that will stick, that isn't sheet linoleum.
Suggestions and ideas?
