I want to buy clear vinyl floor covering which i can put on carpet that i recently had professional cleaned?
Most stores like Walmart, Meijer, Kmart sell clear floor runners that are made of a heavy duty rubber. These are picky on the bottom to prevent slipping. From the sounds of things, you are looking for something clear that will cover the whole floor and not just the high traffic areas. Most people just cover the high traffic areas. Otherwise, my suggestion is to get floor runners that are like pieces of carpet. These can also be purchased from the above mentioned stores or your local carpet store may have scraps you can use.
If you have FRED’S, they have it really cheap. Also, Check with a FABRIC or SEWING store that carries upholstery fabric or coverings. Sometimes they have clear vinyl, sold by the yard just as fabric, used to make upholstery covers. Actually bigger than a simple runner. So, depending on how much you need, this may be your source to try.
