Select a leather recoloring kit. Most kits come with multiple color selections, a leather prep solution, finishing sprays, a spray unit, gloves and sponge applicators. Make sure your kit has the color you desire. The kits usually come with small portions of colors meant to match the existing color of leather. If you are changing the color, you might need enough for multiple layers of color. If so, select your color and purchase an additional bottle of that shade.
Cover your work area. Use newspaper, a sheet or plastic covering to protect other furniture and items from exposure to chemicals.
Remove your leather furniture's existing color. Using the sponge, apply the prep solution on the leather and rub it in with an abrasive pad. The leather prep cleaner removes the manufacturer's finish as well as dirt; it degreases the leather so the new color can fully penetrate. Not prepping your leather will cause adhesion problems. Continue this process until you start to see the color lifting from the leather, exposing the color beneath. You will see excess color on your abrasive pad.
Add a thin layer of color to your leather with a different application sponge. Apply it in smooth, even strokes. Applying the color too thickly will cause bubbles and runs. If you notice this, take a cloth and immediately smooth the surface. Allow the layer to dry. Repeat this step by applying additional layers until you achieve the desired color.
Attach the spray unit to the color pick-up tube. Hold the spray unit 6 to 8 inches away from the surface of the furniture. Apply a thin, even layer of color. Allow to dry.
Apply a thin layer of finishing spray. Allow the spray to dry. Wait approximately 48 hours before disturbing your furniture.
