Make sure to get a rug pad made of vinyl; materials like plastic or rubber might discolor wooden floors. [3] X Research source
Make sure the rug is upside down for this, with the bottom of the rug facing upwards. [4] X Research source
You can keep the rug pad trimmings for future projects, but likely you’ll just want to throw them away. [5] X Research source
While sticking tape on the perimeter of the rug is sufficient, you can cut a few extra strips for the center of the rug if you want a better grip on the rug pad. [6] X Research source
If the rug still moves, you may need to reapply the rug pad. It’s also possible you need a rug pad of a different material, depending on your floors finish. Ask a home improvement professional for guidance. [9] X Research source
Acrylic-latex caulk is best for this purpose. Alternatively, you can use a hot glue gun to lay out grippy strips; the process will be essentially the same. [10] X Research source
Make sure to wait until the caulk (or glue) is completely dry. Placing the rug on the floor before everything’s dried will cause the rug to stick to the floor and damage it. [11] X Research source
