I was wondering what peoples opinions are on the subject of replacing an above ground vinyl liner, while leaving the original bottom layer intact and not removing...? Considering there is no issues with the original bottom having zero wrinkles, bumps or footprints while installing new liner over top, would there be any reason not to leave original bottom in place? Some say they find it easier to spread the new liner flooring out while filling due to it having less friction than sand. While also adding, leaving the underlaying sand layer intact, eliminates the need to smooth out for new install.
Has anyone ever done this? Is there any issues that would arrise with vinyl to vinyl conatact over time causing degration or wrinkles?
