When you walk on your antique rug, it encounters a lot of stress against the hard floor. The back of the rug, or the knots, as well as the foundation, need to be protected as best as possible. There are rug pads with holes in them and solid rug pads. In this case, the solid on is best. Moving a step ahead, a solid pad with some sort of texture on the surface is even better. This texture can safely grab your antique rug and keep it from crawling, hence reducing wear.
For finding a rug pad that provides cushioned support, we need to look at thicker pad products that are available. There are thicker open mesh PVC products from China that provide some cushion support. But there is a limit to how thick these products can be due to the way they are made. The core material that is coated with the PVC is a polyester yarn that is knitted into a wide continuous roll. The roll is then fed into a big oven where it is dipped into the PVC material and allowed to cure in an oven. When PVC cures, it expands and has the texture of a sponge thus giving it good gripping properties. But the overall thickness of this pad is controlled by making the knitted material differently so that it can absorb more of the PVC when coated. So the polyester material is a limiting factor to how thick the PVC mesh can be. 1/8" is the approximate maximum thickness we found for this product. Another product that provides cushion support is the rubber backed felt rug pads that are approximately 1/4" thick. We also found felt pads that are approximately 1/2" thick with no rubber backing that provide exceptional cushion support properties. The felt pad types are made with recycled carpet yarns and are fed into a needlepunch machine that creates a specified thickness, 12' wide felt material which is very dense and durable.
Another important function of a rug pad is to find one that will work on top of carpet flooring. Putting a rug on top of carpet is very common. But rugs tend to move and buckle a lot when over carpet. We looked at all of the rug pad types and found the best rug pad for using over carpet is the rubber backed felt rug pads. The installation needs to be the reversed from when using with hard surface flooring. To properly install over carpet, put the felt side to the carpet and rubber side of the pad against the rug. It is amazing how effective this product is for using over carpet.
