Peel off the old overgrip completely. If you're replacing the base grip (the thick one), remove that too. Ensure the handle surface is clean and dry.
Remove the plastic backing. Place the tapered end of the grip at the bottom of the handle. Hold it firmly with your thumb and begin wrapping tightly.
As you wrap up the handle, overlap the previous layer by about 1/8 inch (or slightly less). Keep tension on the grip tape as you turn the racket.
When you verify the top, trim any excess with scissors (at an angle). Secure the end with the finishing tape provided in the pack.
