Stay Put Rug Grips are the inexpensive way of keeping your rugs from curling, lifting, and shifting for good! Each package comes with 8 grips that adhere to the back of a rug and become permanent. Our package has a diagram to show you where to place the rug grips on the back of your rug so that you get the optimum placement for the best bond. Directions for floor and rug backing: 1. Floor and rug backing must be clean and dry. 2. Position the rug where you'd like to place it. 3. Hold tab and peel liner from grip, then place side that was peeled on the back of rug, will become permanent. (See diagram for placement) Do not extend tab beyond rug edge. 4. Peel liner off opposite side and press rug firmly to clean floor or carpet. Our grips will not damage your existing flooring, will not raise the height and cause a tripping hazard, and will not leave debris. If using Rug Grips on a rug over existing carpet, the carpet must be in "like new'' condition. This is referring to the surface fibers being free of any accumulated contaminants; IE floor cleaning residues from carpet and hard surfaces in the home. If residue is present, at a minimum, clean area where Rug Grips will be touching carpet with a neutral ph cleaning agent.
