I am helping to spruce up a kitchen. The house was built in 1970. It has the original vinyl sheet flooring with a newer vinyl sheet on top. My mom wants the allure planks that look like tile. I think we have to take up the newer vinyl sheet which I think is a bit foamy/squishy. Is 2 layers if vinyl too much to go under the allure? I'm worried with the thickness of the allure the resulting flooring may seem too high although it will be fine meeting up with the carpet at one door and hardwood at the other door.
