Our Outdoor Patio Rug Pad cushions outdoor rugs from abrasive surfaces like stone, concrete, tile, brick and wood. The coated polyester fibers won't break down from exposure to heat or water, and increases breathability to allow for quicker drying. Naturally antimicrobial, mold and mildew resistant. And as you can expect only from Con-Tact Brand® brand products, our high quality rug pads lead the industry in superiority and value. Con-Tact Brand is the only patented (pending) rug pad that replaces petroleum based oils with plant based oils, while maintaining the integrity and design of the product. Our commitment to the research and development of innovative new products helps to ensure that we continue to be the industry leaders. We stand behind our products to be superior and sustainable. One-year limited warranty.
