It is extremely important, no matter how smooth your floor may appear to be, to always place a suitable padding between the floor and your rug. Ideally, a pad should:
- Keep the rug from slipping
- Absorb the pounding that all rugs receive underfoot
- Allow for air circulation, which will prolong the life of your rug
- Be cut one inch smaller in length and width than the rug itself
There are a number of underlays on the market today. The two most widely used are those made from porous sponge rubber and those made from a combination of fibers with a self–adhering coating that looks like a compressed sheet of cotton. The rubber underlay is used on hard surfaces like hardwood, tile, stone or concrete. The self–adhering underlay is mostly used when placing an Oriental rug on wall–to&ndwall carpeting.
Zin Home does not recommend placing rugs on wall–to–wall carpeting, as rugs of all construction have a tendency to float or crawl, stretch and wrinkle in these situations, especially when heavy furniture is being placed on them. If you do wish to place a rug on top of wall–to–wall carpeting, it is best to lay it on carpeting that has a short pile. The low–pile commercial broadloom carpeting that banks and department stores use is ideal.
Note of caution: Do not use sheets of plain foam rubber on a polished floor. They tend to collect moisture that will cause stickiness. The dampness will also cause deterioration of your rug.
